Rules in force · 9Non-EU visitors get 90 days in any rolling 180-day window…
- Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
- Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
- Iberia ↗Plan meals on the Iberian clock: Spanish kitchens serve lunch from about 13:30–14:00 and dinner from 20:30–21:00; Portugal eats an hour or so earlier. Early evenings are for tapas or petiscos, not full meals.
- Iberia ↗Inland Spain and Portugal (Seville, Córdoba, Madrid, the Alentejo) pass 40 °C in heatwaves from late June to August: sightsee before 11:00 and after 18:00, and keep July–August for the coasts and the green north.
- Iberia ↗Andorra and Gibraltar have their own border and customs rules and are reached only through Spain (or France for Andorra); read their pages before adding them, especially if you hold a limited Schengen visa.
- Spain ↗Spain is in the Schengen area. Check the entry rules for your passport on official sources; the EU's Entry/Exit System registers non-EU visitors at the first Schengen border, and further pre-travel authorisation rules are being introduced.
- Spain ↗High-speed trains have airport-style baggage screening at the station and boarding gates that close a few minutes before departure: arrive early.
- Spain ↗Carry your passport or ID: police may ask for it, and hotels must register every guest's document.
- Spain ↗The Alhambra in Granada and the Sagrada Família in Barcelona sell timed tickets that sell out weeks ahead in season; book on the official sites before you fix your dates.

Aigüestortes i Estany de Sant Maurici is Catalonia's only national park and the core of the Pyrenees' glacial lake country: nearly 200 lakes, granite and slate peaks up to 3,017 m at Besiberri Sud, and U-shaped valleys left by ice. It has two classic gateways — the flat, meandering Aigüestortes plain above Boí in the west, and Sant Maurici lake below the twin Encantats peaks above Espot in the east — plus quieter approaches from the Vall Fosca in the south and the Val d'Aran in the north. There is no entrance fee and no permit for day visits; what you pay for is transport, because cars stay in the entrance car parks and you continue on foot or by 4x4 taxi. That single rule shapes every plan: pick your side, get up early, and walk.

Accessibility

- Sant Maurici lake is reached by 4x4 taxi, reducing the climb; the lakeside path is gentle.
- High refuge routes and the Colomers cirque are rough and steep; not suitable for limited mobility.
Visiting lightly

- Carry out all rubbish; camping and fires are forbidden in the park.
- Book refuge beds and stay in valley villages so the local economy benefits from the park.
Questions people ask
How much does it cost to enter Aigüestortes i Estany de Sant Maurici National Park?
There is no entrance fee for the national park itself (check). You pay only for transport: the 4x4 taxi from Boí to the Aigüestortes plain or from Espot to Sant Maurici lake starts at €5.75 per adult, the seasonal park bus (June–September) charges by boarding and alighting point, and the Vall Fosca cable car runs July–September.
What are the best hikes in Aigüestortes i Estany de Sant Maurici National Park?
For an easy day, the flat Aigüestortes plain above Boí and the lakeside path at Sant Maurici below the Encantats. For something harder, the Colomers cirque from Banhs de Tredòs or the Cavallers dam and Besiberri valley. All start from car parks; cars stay outside the park.
When is the best time to visit Aigüestortes i Estany de Sant Maurici National Park?
Mid-June to September for open high trails and the park bus, or late September to mid-October for clear, cooler days and golden larches with fewer people. Avoid August midday crowds and afternoon storms, and expect snow and ice from November to May.
Can I drive into the park?
No. Cars must be left in the entrance car parks, such as La Farga for the Boí side or Prat de Pierró for Espot. From there you walk or take a 4x4 taxi up to the Aigüestortes plain or Sant Maurici lake.
Do I need a permit to visit?
No permit is needed for day visits. You do need to book beds at the mountain refuges for multi-day routes, especially in July and August.
How do I get to the park without a car?
Alsa bus lines link Barcelona, Lleida and Puigcerdà with towns around the park. From June to September the park bus runs twice daily between Boí and Espot via the Val d'Aran, timed to connect with the 4x4 taxis and refuges.
