Sierra de Bernia is the kind of place that shows how wild and beautiful our inland landscape can be. This rugged ridge rises sharply inland from the Mediterranean and stretches across the border between Marina Alta and Marina Baixa, with peaks that soar over 1,100 meters, creating dramatic panoramic views.

The walk to the famous Forat, a natural tunnel carved through rock, is a true “wow” moment. Step through and suddenly you’re greeted by a sweeping window onto the sea. Nearby, you’ll encounter the ruins of the 16th-century Fort de Bernia, built under Felipe II as a lookout and now serving as a silent guardian of the coast below.

What I love most is the contrast, you go from shaded forest trails to barren limestone peaks in minutes. Along the way, you’ll spot wildlife like foxes and birds of prey and the landscape tells stories of centuries past through terraced fields, hidden paths and microclimates full of unique vegetation. Whether you're up for a full-day hike or a quick adventure, Sierra de Bernia always delivers a mix of history, nature and a spectacular sense of place.
