If you like walking, bring your boots. Castell de Castells is one of those places where you don't have to drive an hour to find the mountains: the Serrella and Aixorta ranges rise straight from the village, the marked trails start from the streets themselves, and the paths are waymarked in white and yellow. A walking holiday on the Costa Blanca doesn't have to mean staying on the coast; from here you walk straight out into the hills, from gentle half-days to serious mountain routes.
Walks from the village

Els Arcs, the stone arches
The walk everyone should do first. Els Arcs are two enormous natural arches of limestone, formed by erosion over thousands of years on the northern face of the Serra de l'Aixorta, and protected as a Municipal Natural Park since 2005; the surrounding area holds prehistoric rock art too. The signed PR-CV 151 circular starts at the Pla d'Aialt on the CV-752 towards Tarbena, with parking and an information panel. Go early in summer; there's little shade up there.

El Castellet, the old castle
This one climbs to the ruins of the old castle of El Castellet, perched above the village, with long views over the rooftops and down the valley. The official PR-CV 149 circular starts at the El Castellet recreation area, and you can walk up from the village and link into it. Steady rather than steep.

Font Nova and Font de la Retura
A quieter walk through the old water routes above the village, passing the Font de la Retura and Font Nova before looping back through the mountain landscape. Parts of the route follow the PR-CV 168, with old paths, springs and traces of the village's agricultural past. Lovely in spring when the terraces are green.

Pla de Petracos, the rock art sanctuary
Walk from the village museum down the old valley route to the Pla de Petracos sanctuary, where prehistoric paintings survive in a series of rock shelters beneath the limestone cliffs, explained on interpretive panels. The art dates back around 8,000 years and forms part of the UNESCO World Heritage listing for the Rock Art of the Mediterranean Basin. It feels a world away from the coast, particularly outside the main summer season. Drivers can shortcut it: the sanctuary sits 5 km from the village with parking nearby.
Big mountain days

Morro Blau and the Aixorta
The big local route: the PR-CV 150 traces the high ground of the Aixorta above the village, a genuine full day out with the best ridge views in the area. Save it for settled weather and fresh legs.

Malla del Llop, the Serrella summit
The highest summit of the Serrella at 1,361 m, and a proper mountain day rather than a long walk. The route from Castell de Castells climbs through the Castellet country towards Malla del Llop, with rough and in places exposed ground near the summit. Good weather, proper boots and a head for heights are essential; from the top the whole Marina Alta is at your feet, sea included on a clear day.

The Vall de Laguar 6,000 steps
The famous one: the PR-CV 147, thousands of old stone steps zigzagging into the Barranc de l'Infern gorge and out again. They call it the cathedral of hiking on the Costa Blanca, and your knees will call it other things. Utterly worth it, best outside high summer, about half an hour's drive from the village, and a packed lunch from our kitchen goes down very well at the bottom.
