More ways to explore the area's outdoor wonders
You step out of the minivan onto a cool, granite ridge and the wind from the Atlantic seems to follow you inland, tugging at the pines and the hem of your jacket. Serra D’Arga opens as a working mountain — slate terraces, craggy outcrops and a narrow track that slides down toward a green-cleared bowl where water collects into a bright, cold lagoon.

Footwear for wet stone
Wear sturdy shoes with good grip — the approach to the lagoon uses uneven, sometimes slippery rock and dirt tracks.
Bring a small towel and quick-dry swimwear
The lagoon is cold and the turnaround is swift; a compact towel and swimwear make a dip comfortable without extra baggage.
Timing for light and crowds
Start later in the afternoon if you want warmer air for a swim and quieter trails; mornings can be misty and cooler.
Cash-friendly dining
The mountain restaurant focuses on traditional service — carry a small amount of cash for tips or extras in case card service is limited.
