Paragliding above Interlaken is one of the great visual experiences in European aviation. The Eiger's north face, the Jungfrau snowfields, the lakes of Thun and Brienz spread below — it is the kind of backdrop that earns a destination its worldwide reputation. The tandem flights booked in their thousands every summer are, for most passengers, genuinely life-changing. But for a licensed paragliding pilot asking a different question — where can I go to actually improve as a pilot? — Interlaken tells a more complicated story. This is that story, and an honest comparison with what a coaching week in Portugal offers instead.
Why Interlaken Is World-Famous — and Rightfully So
The Berner Oberland is arguably the most dramatic Alpine scenery accessible to a paraglider. Launch from Beatenberg above Lake Thun and the view encompasses three 4,000-metre peaks, two glacier-fed lakes, and the distinctive green valley floor of the Aare. In good conditions the flight is smooth, the thermal cycle predictable in the morning, and the sense of scale genuinely unlike anything available in lowland Europe.
Interlaken is also exceptionally well-connected for a Swiss destination. Zurich airport is 1.5 hours by train or car; Bern is 45 minutes. The town has excellent tourist infrastructure — hotels at every price point, good restaurants, reliable public transport. For a non-pilot partner accompanying a flying pilot, Interlaken offers hiking, the Jungfraujoch railway, kayaking, and the full slate of Swiss adventure tourism. It is one of the best places in Europe to spend a week if flying is one of several activities rather than the only focus.
The Reality for Licensed Pilots — What Interlaken Offers and What It Doesn't
The paragliding at Interlaken is dominated by tandem operations. This is not a criticism — the demand is genuine and the operators are professional. But it shapes the entire flying environment in a way that solo pilots planning a coaching week often underestimate before they arrive.
The main launch at Beatenberg above Lake Thun sees dozens of tandem flights per day in peak season. Slots are allocated, the air is busy, and the culture is oriented around maximum passenger throughput rather than pilot development. Finding a guide willing to fly XC with a visiting licensed pilot, provide radio coaching, and debrief track logs over dinner is not impossible — but it is not the infrastructure that exists here. The few free-flight pilots who do visit typically arrive self-sufficient, knowing the site and needing no hand-holding.
Visiting licensed pilots at Interlaken most commonly report: limited XC routing due to crowded valley airspace and frequent traffic from Bern-Belp airport; a short thermal window before valley winds arrive in the afternoon; no coaching infrastructure; and a cost structure that makes Portugal or the French Alps significantly better value. The scenery is exceptional. The pilot development environment is not.
Season and Conditions
The reliable flying window at Interlaken for thermal XC is June through September — four months. Outside this window, Alpine weather makes conditions unpredictable and the thermal cycle unreliable. Even within the season, Swiss weather can be changeable; a week in July or August may include two or three non-flying days due to afternoon storms or unstable Atlantic systems pushing in from the west.
The thermal cycle on good days is cleanest in the morning — launches from Beatenberg from around 10 am, with thermals triggering off the south-facing slopes as the sun hits them. By early to mid-afternoon the valley wind from the west can arrive, creating turbulent mixing on the lower ridges. The XC window is therefore often shorter than pilots expect. Experienced Alpine pilots know to be on launch early; visitors sometimes miss the best of the day waiting for conditions to develop.
Airspace and XC Potential
The airspace situation around Interlaken is more constraining than it appears on a first look at the map. Bern-Belp airport's CTR extends over much of the valley floor to the west. Lauterbrunnen valley, while visually spectacular, is a dead-end XC route — pilots fly in and must turn back. The routing east toward Grindelwald and the Grindelwald Fieschertal opens terrain options but the airspace around Innsbruck TMA and various military zones requires careful planning.
Typical XC distances from Interlaken for a competent intermediate pilot on a good day run 30 to 60 km before airspace, terrain, or the weather window closes the route. Exceptional days produce longer flights, but these require skill, local knowledge, and timing that visiting pilots rarely have on a first trip.
The Cost of a Week in Interlaken
Switzerland is one of the most expensive countries in Europe to visit. A realistic budget for a week's paragliding holiday in Interlaken — flights from the UK or Germany, modest accommodation, food, and a day's guided flying — runs to €1,600 to €2,400 per person. Hotels in Interlaken town in July and August start at €100 per night for anything decent. Restaurant meals are 40 to 60% more expensive than equivalent meals in Portugal or Spain. Even grocery shopping is expensive by European standards.
Zurich flights are generally well-served but not the cheapest routes from Northern Europe — budget airlines serve Zurich and Geneva, but fares are typically higher than routes to Lisbon. The overall cost comparison with a coaching week in Sesimbra is substantial.
Interlaken vs Sesimbra — Side by Side
| Factor | Interlaken, Switzerland | Sesimbra, Portugal |
|---|---|---|
| Flying season | June–September (4 months) | Year-round (10+ months) |
| Primary focus | Tandem tourism; self-guided free flight | Coached flying; XC and coastal |
| Radio coaching available | Rare; not standard | Standard on every flying day |
| Typical XC distance | 30–60 km | 60–150+ km (Alentejo) |
| Accommodation cost | €100–180/night peak season | €50–90/night year-round |
| Nearest airport | Zurich (1.5 hr) or Bern (45 min) | Lisbon (30 min drive) |
| Flight cost (UK) | £120–250 return typical | £60–150 return typical |
| Airspace freedom | CTR constraints; valley routing limited | Open; unrestricted below 1,500 m |

| Group size (coaching) | Not applicable (self-guided) | Max 5–8 pilots |
Who Should Go to Interlaken
Interlaken earns its place on every pilot's bucket list — but for specific reasons. If you want the Alpine experience, the Eiger backdrop, and the unique character of Swiss mountain flying, Interlaken is the correct destination. It is also the right choice if you are travelling with a non-pilot partner for whom the Swiss adventure tourism infrastructure matters. A tandem flight above Interlaken is a genuinely spectacular gift or shared experience.
It also suits experienced self-guided pilots who know the site and are coming for the specific terrain — the Lauterbrunnen soaring, the morning thermal cycle on the Beatenberg south face, the occasional exceptional XC day when conditions align. These pilots arrive with local knowledge, their own kit, and no need for coaching infrastructure.
Who Should Come to Portugal Instead
Pilots whose primary goal is to return home a better pilot — more XC confidence, improved thermalling technique, better weather reading, longer flights — will almost always achieve more in a week in Sesimbra than a week in Interlaken. The coaching infrastructure is purpose-built for exactly that outcome: small groups, daily radio coaching, track log debriefs, and a flying environment that operates for ten months of the year rather than four.
Budget-conscious pilots who want to maximise flying time per euro get substantially better value in Portugal. The same week that costs €2,000 in Interlaken can be done in Sesimbra for €900 to €1,200 — with more flyable days and more hours in the air. And the coastal soaring on Portugal's Atlantic ridge has no Alpine equivalent: it is a completely different type of flying that Interlaken simply cannot offer.
