Interlaken vs Sintra

Interlaken

Interlaken town sits at 568 m in a valley with a relatively mild alpine climate, but the mountain destinations it serves range from 1,000 m (Grindelwald) to 3,454 m (Jungfraujoch). Temperature drops roughly 6°C per 1,000 m gain — a pleasant 22°C day in town means 0°C at the Jungfraujoch. Clouds are a serious consideration: the Jungfraujoch can be socked in for days at a time even when Interlaken is sunny, so building flexibility into your itinerary for high-elevation excursions is genuinely important. Check the Jungfrau webcam the evening before any planned ascent.

Sintra

Sintra's microclimate is famously different from Lisbon just 28 km away — the Serra de Sintra intercepts Atlantic moisture, creating a cool, misty, perpetually green environment. Summer days are often clear and warm above 500m while the serra is in cloud. Winter is mild (rarely below 8°C) but wet and foggy.

Interlaken

Interlaken is a model of Swiss public transport connectivity. Two train stations — Interlaken West (trains to Bern and Thun) and Interlaken Ost (trains to Grindelwald, Lauterbrunnen, and the Jungfrau region) — sit at opposite ends of the Höheweg. The Swiss Travel Pass covers SBB intercity trains, most PostBus routes, the lake boats, and gives 25% off most mountain railways. It does NOT cover the Jungfraujoch surcharge (CHF 45 from the Eigergletscher junction). A car is unnecessary and often counterproductive — Grindelwald, Wengen, and Mürren have limited or no car access.

Walkability: Interlaken town itself is easily walkable — Interlaken West to Interlaken Ost along the Höheweg takes about 25 minutes on foot. The Höhematte meadow, main shops, restaurants, and the Aare river are all within a 10-15 minute walk of either station. Mountain villages like Grindelwald and Lauterbrunnen are reached entirely by rail and cable car from the valley.

Sintra

The historic village centre is walkable but steep. Between palaces, Bus 434 is the best-value option connecting the train station, Old Town, Moorish Castle, and Pena Palace. Bus 403 continues to Cabo da Roca and Cascais.

Walkability: Moderate in town centre; steep paths to palaces require fitness. Bus 434 essential for most visitors.
