Packing for Interlaken is harder than it looks, because a single day can cover a lakeside café in the valley and a snowy platform thousands of meters higher. The town sits between Lake Thun and Lake Brienz, with trains, funiculars and cable cars climbing straight up from it, and the weather changes with every stop. When I plan a wardrobe for this region, I build it around layers that come off and go back on in a minute, and shoes that handle wet rock as well as town streets. Below are 25 complete outfits for every season, from paragliding and lake cruises to the Jungfraujoch in winter, each one matched to the activity it's meant for.
How the Weather Changes Between the Valley and the Peaks
Interlaken itself sits at around 570 meters, but most of what people come to see is far higher. As a rough rule, air cools by about six to seven degrees Celsius for every thousand meters you climb, and wind makes it feel colder still. So a warm summer afternoon in town can be close to freezing at the Jungfraujoch on the same day.
- Summer: warm, often humid afternoons in the valley with frequent thunderstorms building over the mountains. Pack a rain shell and a fleece even in July.
- Autumn and spring: wide swings between morning and afternoon. Merino and a light down jacket cover most of it.
- Winter: the valley is often cold and grey while the peaks are sunny above the cloud. You need insulated boots and sun protection on the same day.
The practical answer is layering. I plan every outfit here so the top layer can come off and go into a small bag, and the base layer is something you'd be happy to be seen in on its own.
1. Summer Interlaken Hiking Outfit with Moisture-Wicking Top and Trail Pants
For a bright July hike above town, I start with a moisture-wicking short-sleeve tee in a neutral and lightweight convertible hiking pants that zip off when the valley warms up. Trail runners with a grippy sole handle the steep, rocky switchbacks on routes like Harder Kulm and Schynige Platte; I'd only choose full boots if your ankles need the support. A wide-brimmed hat and wraparound sunglasses matter more at altitude, where the sun burns faster. A packable rain jacket lives in the daypack all day, because afternoon showers build quickly over the peaks. A hydration pack finishes it.
2. Paragliding Adventure Outfit with Leggings and Windproof Jacket
A tandem paragliding flight starts with a short run downhill, so the outfit has to let you move. High-waisted athletic leggings and a fitted long-sleeve thermal keep you warm without bulk, and a windproof softshell blocks the cold air at launch height. Closed sneakers with good ankle support are non-negotiable for take-off and landing. Tie hair in a low braid and wear close-fitting sunglasses that won't fly off. Thin gloves help on cool days. Skip loose scarves and dangling jewelry, which tangle in harness straps.
3. Jungfraujoch Excursion Outfit with Layered Puffer and Snow Boots
The Jungfraujoch sits at roughly 11,300 feet, and it's cold up there even in August, often around freezing with wind on top. I layer from the skin out: a merino base top and thermal tights, a fleece mid-layer, then a packable puffer that traps heat without bulk. Insulated waterproof boots with deep tread grip the icy terraces. A chunky beanie, thick scarf and touchscreen gloves keep you warm while you take photos. Snow reflects strong UV at that height, so UV-blocking sunglasses and high-SPF sunscreen are essential, even on cloudy days.
4. Lake Brienz Boat Cruise Outfit with Linen Dress and Sun Hat
A Lake Brienz cruise is the moment for a white linen midi. Linen stays cool in sun and dries fast if spray reaches the deck, and it moves in the breeze. Flat cushioned leather sandals keep you steady on stairs between decks; I'd avoid heels on boats. A wide-brimmed straw hat needs a chin cord or a firm hand on the open upper level. Oval sunglasses, a woven rattan crossbody and a light cotton cardigan over the shoulders for the cooler air on the water finish it.
5. Autumn Iseltwald Outfit with Cable-Knit Sweater and Ankle Boots
The lakeside path near Iseltwald in October is all gold leaves and damp ground, so I dress for both. A chunky cream cable-knit tucked into medium-wash high-waisted straight jeans gives warmth and texture. Waterproof leather ankle boots with lug soles are the important piece; leaf-covered paths get slippery after rain. A plaid wool scarf, a burgundy or forest-green quilted crossbody and a wool fedora complete it. Cable knits trap more air than flat knits, which is why they feel warmer at the same weight.
6. Höheweg Promenade Outfit with Cropped Jeans and White Sneakers
Walking the Höheweg, the long promenade with gardens and mountain views, is something you'll do daily, so it deserves a reliable outfit. A white button-down with sleeves rolled to the elbow, loosely tucked into cropped straight jeans that end above the ankle, works in most weather. Clean white leather sneakers are my first choice for a town where you walk everywhere; they look neat and go all day. A slim brown belt, a tan structured crossbody and a light knit across the shoulders for cooler hours finish it.
7. Interlaken Café Outfit with Slouchy Overalls and Striped Tee
For a slow coffee on a terrace along the Höheweg, slouchy medium-wash overalls over a Breton long-sleeve tee look relaxed and travel-ready. The stripe at the neck and cuffs keeps the denim from feeling plain. Platform canvas sneakers add a little height, and a roomy canvas tote holds a journal, sunglasses and souvenirs. Small gold hoops and a pendant are enough jewelry. One honest trade-off: overalls are slow to get out of in a café restroom, so choose a pair with side buttons.
8. Winter Interlaken Outfit with Down Jacket and Insulated Boots
Snowy Interlaken streets mean cold feet and slushy train platforms, so I start at the boots: insulated, waterproof and with a sole that grips ice. Above that, thermal base layers, a merino turtleneck and fleece-lined leggings under waterproof trousers. A longline down coat with a hood covers the hips, which matters far more on a long platform wait than a short jacket does. A chunky cream beanie, leather mittens and a thick scarf finish it, with a small backpack for gloves and a thermos.
9. Harder Kulm Viewpoint Outfit with Fleece Jacket and Hiking Shoes
The Harder Kulm funicular takes about ten minutes, and the top can feel noticeably cooler and windier than the valley. A light fleece pullover in oatmeal or slate over a quick-dry short-sleeve tee handles the change. Straight hiking pants with stretch let you explore the viewing deck and short trails nearby. Waterproof low hiking shoes with a solid lug sole grip the wooden platforms when they're damp. A cap and a small daypack with water and a spare windbreaker finish it. Neutral colors look natural against the Two Lakes Bridge backdrop.
10. Lake Thun Sunset Walk Outfit with Midi Dress and Cropped Cardigan
A sunset walk along Lake Thun calls for something softer. A silky floral midi in terracotta or mustard with a small slit moves easily, and a chunky cropped cardigan goes over the shoulders when the air cools after sunset, which it does quickly near water. Flat strappy sandals or low block-heel mules handle the shoreline path. Gold jewelry, a slim leather watch and a mini woven bag finish it. Silky dresses cling in wind, so a slip underneath helps. It goes straight from afternoon sightseeing to an early dinner.
11. Grindelwald First Cliff Walk Outfit with Cargo Pants and Sport Sneakers
The First Cliff Walk above Grindelwald runs along metal walkways bolted to the rock, with open grating underfoot and wind coming around the cliff. Olive or sand cotton-blend cargo pants give pockets for your phone and lip balm with free movement. A ribbed tank under a zip-up hoodie lets you adjust as you climb. Cushioned sport sneakers are comfortable on the metal, though avoid anything with a thin heel that could catch in the grating. Clip a small crossbody across your chest to keep your hands free for the railings, and tuck hair under a cap.
12. Rainy Day Interlaken Outfit with Waterproof Trench and Rain Boots
Rain is part of any Interlaken trip, especially in late spring and early autumn. A beige waterproof trench with a belted waist keeps you dry and still looks put-together in town. Slim black jeans tuck into glossy mid-calf rain boots with a small heel. A light cashmere-blend sweater in navy or charcoal adds warmth without bulk. A clear dome umbrella lets you see the misty mountains while you walk, and a water-resistant nylon crossbody protects your phone. Check the trench is actually waterproof, not just water-repellent; many fashion trenches soak through in an hour of steady rain.
13. Ski Trip Interlaken Outfit with Insulated Ski Suit and Snow Goggles
Skiing in the Jungfrau region means proper gear first and style second. A streamlined insulated ski jacket with matching slim ski pants keeps you warm and mobile. Underneath, a moisture-wicking thermal set and merino ski socks regulate temperature through the day; cotton socks hold sweat and leave feet cold. Waterproof gloves, a helmet and anti-fog goggles protect against wind and glare. White or pastel outerwear looks bright in photos, though bold colors are easier to spot on the slope. Clip your pass holder to a sleeve or zip pocket.
14. Après-Ski Chalet Outfit with Chunky Knit Sweater and Faux Fur Boots
After a day in stiff ski boots, it feels good to change into something cozy and chic for the chalet. An oversized ivory or charcoal chunky turtleneck over thermal leggings or slim base-layer pants keeps you warm by the fire. Faux fur-lined boots are pure comfort, though most aren't waterproof, so keep them for short walks on cleared paths. A double-faced cashmere scarf, a slouchy beanie and a leather backpack purse complete it. It works for fireside drinks or a casual dinner at a mountain restaurant.
15. Bönigen Beach Afternoon Outfit with Tank Top and Linen Shorts
On warm August afternoons, the pebbly shore at Bönigen on Lake Brienz is the place for a swim. A white ribbed tank and high-waisted sandy linen shorts go over your swimsuit, with a sheer cotton cover-up for walking between water and shore. Slides that can get wet are important on the pebbles; water shoes are even better if your feet are sensitive. A wide-brimmed straw hat and big sunglasses handle the sun, which is strong at this altitude even when the lake feels cold. A water-resistant drawstring bag holds a towel, sunscreen and a book.
16. Interlaken Airport Travel Outfit with Matching Knit Set and Sneakers
Getting to Interlaken usually means flying into Zurich or Geneva and taking the train, so the travel outfit has to handle a long day. A heathered gray knit set, crewneck and tapered joggers, looks coordinated and feels like loungewear. A longline wool-blend coat on top covers the plane and the brisk Swiss air on arrival. White platform sneakers support your feet through transfers. An oversized leather tote holds documents, a book and a scarf. Knit sets bag at the knee after hours of sitting, so pick a dense, firm knit rather than a loose one.
17. Swiss Fondue Dinner Outfit with Dark Jeans and Cashmere Turtleneck
A fondue dinner in a traditional Swiss restaurant means a warm room and a long meal. Slim dark jeans with a little stretch stay comfortable through several courses. A fitted cashmere turtleneck in crimson or forest green looks rich by candlelight, though fondue smells cling to knitwear, so air it outside overnight. Block-heel leather ankle boots handle cobbles with a dressy lift. Gold drop earrings, a leather watch and a tailored wool coat over your arm finish this polished evening outfit.
18. April in Interlaken Outfit with Trench Coat and Merino Sweater
April in Interlaken swings from crisp mornings to warm afternoons and back to showers. A light heather-blue merino crewneck tucked into high-waisted grey tailored trousers handles the range, since merino stays comfortable across wider temperatures than cotton. A khaki double-breasted trench covers the drizzle. White leather sneakers keep it walkable for the riverside paths along the Aare. A compact umbrella in a structured tote and oversized acetate sunglasses for the low spring light complete it.
19. Unterseen Old Town Outfit with Midi Skirt and Leather Ankle Boots
Unterseen, Interlaken's old-town neighbor, has cobbled lanes and old houses that suit a slightly dressier outfit. A flowy pleated midi skirt in emerald or sapphire with a tucked silky neutral blouse gives a romantic shape. Flat pointed leather ankle boots lengthen the line and won't pinch on uneven stone. I'd avoid thin heels here; cobbles catch them. A cropped leather moto jacket over the shoulders adds warmth, and a matching mini bag with sleek gold earrings finishes the look.
20. Lake Brienz Kayaking Outfit with Quick-Dry Shorts and Water Sneakers
Kayaking on Lake Brienz on a calm summer morning means you'll get wet, so everything should dry fast. An athletic bikini top or rash guard as the base, a loose quick-dry tank on top, and high-waisted quick-dry shorts with a soft elastic waist that won't dig in when you're seated. Water sneakers with drainage protect your feet on rocky launch spots. Clip a floating dry bag to the kayak for your phone and sunscreen, and add polarized sunglasses with a retainer strap. The lake water stays cold even in summer, so bring a dry layer for afterwards.
21. Winter Snowshoeing Outfit with Thermal Base Layers and Waterproof Pants
Snowshoeing is hard work, so the mistake I see most is over-dressing at the start. Begin with a merino base set and a fleece zip mid-layer, then waterproof snow pants with reinforced cuffs to keep powder out. A down jacket with a windproof shell goes on for breaks and comes off on climbs. Waterproof gloves, a fleece-lined beanie and insulated boots with ankle support handle the terrain. Gaiters stop snow getting into your boots, and a trekking pole helps on uneven ground. Start slightly cool; you'll warm up within ten minutes.
22. Schynige Platte Panorama Trail Outfit with Hiking Tights and Windbreaker
The ridge trail at Schynige Platte looks out over the Eiger, Mönch and Jungfrau, and the exposed ridge can be very windy. Full-length high-waisted hiking tights with side pockets hold your phone and snacks and move freely on narrow paths. A long-sleeve technical tee with thumbholes protects your arms from sun. A light windbreaker in a bright color packs into its own pocket when the sun comes out. Trail runners with aggressive tread grip rocky sections. A visor and UV arm sleeves help with the stronger sun at altitude.
23. Interlaken Evening Walk Outfit with Sweater Dress and Chelsea Boots
An evening walk along the Aare deserves a quiet, warm outfit. A ribbed sweater dress in charcoal or camel that skims rather than clings, with black semi-sheer tights, handles the cooler air after sunset. Leather Chelsea boots with a slight platform keep it modern and comfortable. A wool beret and a long wool-blend scarf add warmth, and a small leather crossbody holds the essentials. Ribbed sweater dresses can stretch at the seat over a trip, so hang them over a chair between wears rather than on a hanger.
24. Alpine Meadow Picnic Outfit with Floral Dress and Straw Tote Bag
A wildflower meadow with views of the Jungfrau is the obvious picnic spot. A light floral midi with puff sleeves and a square neck feels airy against the green. Flat espadrilles with ankle ribbons work on dry grass, but swap for sneakers if the meadow is wet, since jute soles soak through. A structured straw tote carries a blanket, cheese, bread and a bottle of wine. Tousled hair, pearl studs, coral lipstick and a delicate gold anklet finish it. Bring a light layer; meadows above the valley cool quickly when clouds come over.
25. Photography Tour Outfit with Neutral Cardigan and Comfortable Flats
A full day chasing photo spots, from the Jungfrau viewing platform to the lake shores, puts comfort first. An oatmeal or blush longline open cardigan over a simple tank or tee layers easily. Stretchy pull-on trousers in a neutral let you crouch and climb for the right angle. Pointed slip-on flats look neat in town, though I'd pack sneakers in the bag for any trail section. A soft leather backpack holds camera gear, a spare lens and water. Neutral clothing also keeps you from clashing with the scenery in your own photos.
Packing for Swiss Trains and Mountain Days in One Bag
Most visitors move around the Bernese Oberland by train, and that means lifting luggage onto carriages and up station steps. A smaller bag makes every transfer easier, and a well-planned capsule covers far more than it looks like it should.
- Two pairs of shoes plus one: trail runners or light hikers for paths, clean sneakers or ankle boots for town, and snow boots only if you're visiting in winter.
- One waterproof shell that fits over a fleece. It does more work than any other piece in the bag.
- Merino base layers that can be worn several days without smelling, which cuts down on laundry.
- One evening outfit built from a knit, dark jeans or a midi skirt, and the same boots you walk in.
- Accessories that pack flat: a beanie, a light scarf, sunglasses and a packable sun hat.
Keep every piece in two or three colors that mix, so any top works with any bottom. Wear the bulkiest items, like boots and the warmest jacket, on the travel day so they're not in your bag.
Pack for the Weather You'll Meet at Every Altitude
Interlaken rewards travelers who pack for change. From a Harder Kulm climb to a linen-dress cruise on Lake Brienz or a snowy day at the Jungfraujoch, a few good layers and the right shoes will carry you through every part of this stunning Swiss destination. Keep a waterproof layer within reach, respect the altitude sun and pack natural fibers like merino, wool and linen that cope with mountain weather. Start with the activities on your itinerary and choose outfits from this list to match them.
