My pick
My tip“Car entry fee (2–7 euros) at Casas de Irati. The loop around the lake takes 2–3 hours.”
The second-largest beech and fir forest in Europe after Germany's Black Forest, stretching across the Pyrenees between Navarra and France. It reaches its peak of beauty in autumn colours around the Irati reservoir.
Moderate effort, needs a car
By car only, up to Orbaizeta and the Casas de Irati car park (fee 2–7 €). The loop around the lake takes 2–3 hours. Cold and humid. Weak signal. Only a small café.
