Alpine Adventure Playground
Interlaken sits on a narrow strip of land between two outrageously blue lakes, backed by the Eiger, Mönch, and Jungfrau. It's the kind of place that looks AI-generated but isn't. The town has spent more than a century turning the Swiss Oberland into an adventure-sports factory, and the infrastructure is world-class: trains that climb to 11,000 feet, paragliding launches with views of three countries, and gorges that feel like they belong on another planet. Here's how to do all of it in three days without blowing your life savings.
Fly into Zürich Airport (ZRH) from Chicago O'Hare (ORD). SWISS and United both run direct routes, and you can land Premium Economy seats for ~$1,195 roundtrip — verify when booking, as fares shift with season and demand. From ZRH, it's roughly 62 miles southeast to Interlaken. You could take the train (scenic, roughly two hours with a change in Bern), but a rental car gives you far more flexibility for reaching trailheads, waterfalls, and the Lauterbrunnen Valley on your own schedule. Pick one up at the airport and you're set.
Drive straight to Interlaken and check into your hotel. After dropping bags, head to Harder Kulm, the town's own panoramic balcony at 4,337 feet. You can hike up (about 1.5 hours on a steep, well-marked trail) or take the funicular (~$35–$40 roundtrip, verify when booking). The viewing platform juts out over the town and frames both Lake Thun and Lake Brienz — it's the single best orientation point in the region.
Come back down and spend the afternoon at Adventure Park Interlaken at Goldey 1. This is one of Switzerland's largest rope courses, with routes strung through the forest canopy ranging from kid-friendly to legitimately terrifying. Budget ~$40–$55 per person depending on the course level, verify when booking. Once your arms are Jell-O, walk next door to the Interlaken Alpine Coaster, a gravity-fed toboggan run on rails that drops through the trees. It's pure, stupid fun and costs ~$10–$15 per ride, verify when booking.
Dinner in town: Interlaken's Höheweg strip has everything from rösti joints to Thai food. Expect ~$25–$45 per person for a solid sit-down meal.
Start early and drive about 20 minutes into the Lauterbrunnen Valley to Trümmelbach Falls. These are ten glacier-fed waterfalls crashing inside the mountain, accessible via tunnel lifts and carved walkways. The sound alone is worth the ~$12–$15 entry fee, verify when booking. Wear a layer — it's cold and wet inside, even in July.
From there, continue to Aabach Gorge near Sundlauenen. This slot-canyon hike follows wooden walkways pinned to sheer rock walls above emerald water. It's shorter and less crowded than the more famous Aare Gorge, and the entry is ~$8–$10, verify when booking. Allow about an hour.
Return to Interlaken for the headliner: Interlaken Tandem Paragliding. You'll launch from a hillside above town and spend 10–20 minutes soaring over the lakes with the Jungfrau massif filling the horizon. Expect ~$180–$220 for a tandem flight with photos and video, verify when booking. If you'd rather go bigger, Interlaken Skydiving operates from Unterseen Airfield — a tandem jump from 14,000 feet runs ~$380–$450, verify when booking. You only need one, and paragliding offers the better scenery-per-dollar ratio. Skydiving is the move if pure freefall is the point.
This is the big-ticket day. Jungfraujoch – Top of Europe is the highest railway station in Europe at 11,332 feet, and the journey there — through tunnels bored into the Eiger — is engineering theater. Tickets run ~$220–$250 roundtrip from Interlaken, verify when booking. Book the earliest departure to beat the crowds and get the clearest skies. Budget four to five hours for the full roundtrip plus time at the top.
In the afternoon, you have a choice. If it's summer (June through October), take the Brienz Rothorn Railway from the village of Brienz on the eastern lakeshore. This steam-powered cog railway climbs to 7,700 feet through wildflower meadows, and tickets are ~$70–$90 roundtrip, verify when booking. Alternatively, the Schynige Platte hike from Wilderswil offers a ridgeline walk with panoramic views of the Jungfrau trio and an alpine botanical garden at the top — the cog train to the trailhead is ~$55–$70 roundtrip, verify when booking.
For a completely different kind of rush, Swiss Raft operates out of Hauptstrasse 10 in Meiringen and runs whitewater trips on the Lütschine and Aare rivers. A half-day rafting outing runs ~$100–$130, verify when booking — a great way to burn off any remaining energy before dinner.
Three tiers, one town. Essential by Dorint Interlaken is the practical pick: modern, clean, centrally located, with rooms starting around ~$150–$200/night, verify when booking. Hotel Beausite offers more character and slightly better views in a mid-range package (~$200–$300/night, verify when booking). And if you want the full grand-hotel experience, Victoria Jungfrau is one of the most iconic properties in Switzerland — expect ~$500–$800/night, verify when booking. For the adventure-focused trip outlined here, the Dorint is the sweet spot: you won't spend much time in the room anyway.
Rent a car at ZRH. Swiss roads are immaculate, parking in Interlaken is manageable, and you'll need wheels to reach Trümmelbach Falls, Aabach Gorge, and Brienz without being hostage to bus schedules. Don't forget the motorway vignette (~$42, required for highway driving in Switzerland) — you can buy it at the border or at the airport. Budget ~$50–$80/day for the rental, verify when booking.
Skip Paragliding Interlaken if you've already booked Interlaken Tandem Paragliding — they're similar experiences offered by different operators, and one flight is plenty. Don't try to add a fourth day of activities; three days is the right density. You'll be tired.
Best window: mid-June through mid-September. The Brienz Rothorn Railway and Schynige Platte train are seasonal, and weather above 10,000 feet is unpredictable outside summer. Shoulder weeks (early June, late September) mean thinner crowds and slightly lower hotel rates. Winter is a different trip entirely — ski-focused, and many of these experiences shut down.
