The Sierra de Bèrnia hike should be high on your list if you’re looking for one of the best Costa Blanca hikes. This spectacular ridge walk offers some of the most panoramic views, stretching from the Mediterranean all the way to the inland mountains.
I’ve put together this detailed guide to help you tackle this fantastic hike safely and make the most of your day in the mountains. You’ll learn about the different route options, what to expect along the way, and all the practical details you need for a successful Sierra Bernia adventure.
Starting points
The most popular starting point for the Sierra Bernia hike is from Casas de Bèrnia or Font de Bèrnia, which are clearly marked trailheads located between Altea and Callosa d’En Sarrià. From Benissa, it’s about a 35-minute drive inland via the CV-715 road.
Parking: There’s a small car park near the trailhead at Casas de Bèrnia, but it fills up quickly at weekends. I’d recommend arriving early, especially during the cooler months when hiking is most popular.
If you’re staying in Calpe, Altea, or other nearby towns, you can also drive to the trailhead – it’s roughly 20-30 minutes from most places along this stretch of coast.
The main Sierra Bernia hiking routes
The classic ridge walk to Fort Bernia
- Duration: 4 hours
- Difficulty: Challenging
- Elevation gain: 450-850 metres
- Distance: 9-11km circular
This is the most popular Sierra Bernia hike and the one most people are referring to when they talk about hiking Sierra Bernia. The walk takes you along the dramatic ridge to the ruins of Fort Bernia, a 16th-century fortress built to defend against Barbary pirates.
The route starts from the trailhead and follows a well-marked path that climbs steadily through pine forests before emerging onto the exposed ridge. The views become more spectacular with each step – on clear days you can see from Valencia to Alicante!

The highlight is reaching the fort ruins, where you can rest and take in the incredible 360-degree views. The old stone walls make a perfect spot for photos, and there’s usually a lovely breeze up here even on hot days.
The tunnel route (Forat de Bernia)
- Total distance: 8.4 – 11km circular
- Duration: 2.5-4 hours
- Difficulty: Medium to challenging
You can extend your hike to include the famous Forat de Bernia – a natural tunnel carved through the rock ridge. This is typically included in the main circular route and is absolutely worth it for the unique experience.

The tunnel itself is about 15-20 metres long and is very narrow and low, requiring you to crouch or crawl through. While daylight is visible throughout, a torch or phone light is helpful for navigating safely. Coming out the other side feels like stepping into another world, with sky views of Altea and Benidorm in the distance.
What to expect on the Sierra Bernia hike
The first part of the walk takes you through lovely Mediterranean woodland with pine trees, wild rosemary, and thyme. You’ll probably hear goat bells in the distance – there are still traditional goat herders working in these mountains. As you climb higher, the path becomes rockier and more exposed.

This is where you’ll start getting those amazing views across the Costa Blanca. The Mediterranean stretches out below you, with spectacular panoramic views of the coastline and inland mountains.
The ridge section is the most dramatic part of the hike. You’re walking along a narrow rocky spine with steep drops on both sides – it’s not dangerous if you stick to the path, but it’s definitely not suitable for anyone with a fear of heights.
Essential kit for the Sierra Bernia hike
Given the exposed nature of this walk, proper preparation is crucial:
- Sturdy hiking boots – the rocky terrain can be slippery, especially if there’s been recent rain
- Plenty of water – at least 2 litres per person, more in summer
- Sun protection – hat, sunglasses, and high-factor sun cream
- Torch or headlamp – helpful if you’re planning to go through the tunnel
- Warm layer – it can be surprisingly cool and windy on the ridge
- Snacks – there are no facilities along the route
Best time to hike Sierra Bernia
I’d strongly recommend avoiding the summer months (July and August) for this hike. The exposed ridge offers little shade, and temperatures can be dangerously high. The best times are: Autumn (September to November): Perfect weather and clearer views Winter (December to February): Cool but comfortable, fewer crowds
Spring (March to May): Wildflowers bloom and the weather’s ideal Start early regardless of the season – not only will you avoid the heat, but the morning light on the mountains is absolutely stunning for photos.
Safety considerations
This isn’t a casual stroll – the Sierra Bernia hike requires a reasonable level of fitness and proper preparation. The ridge sections have steep drops, and the weather can change quickly in the mountains. Always tell someone your planned route and expected return time. Mobile phone coverage is patchy in places, so don’t rely on being able to call for help.

If clouds start rolling in, turn back immediately. The ridge becomes dangerous in poor visibility, and mountain weather can deteriorate rapidly.
Alternative shorter walks in the area
If the full Sierra Bernia hike sounds too challenging, there are some lovely shorter walks starting from the main trailheads at Casas de Bèrnia or Font de Bèrnia.
You can walk partway along the route to enjoy some of the spectacular mountain scenery without committing to the full circular hike.
Where to eat after your hike
After a challenging Sierra Bernia hike, you’ll definitely have worked up an appetite! I’d recommend driving to nearby Callosa d’En Sarrià where you’ll find several dining options.
Bar Refugi is a lovely restaurant near the mountain that serves excellent traditional Valencian food, including fantastic paella that’s perfect for refuelling after a mountain adventure – and exquisite views of Calpe in the distance!

You can find the map below:
If you fancy something closer to the coast, the drive back towards Altea takes you past several excellent restaurants with terraces where you can enjoy your meal while looking back at the mountains you’ve just conquered.
Local hiking tips
The Sierra Bernia area is home to several other fantastic walks if you get bitten by the hiking bug. The nearby Puig Campana is another challenging peak, while the Fonts de l’Algar waterfalls/algar-waterfalls/) offer a completely different but equally rewarding experience.
Local hiking shops in Altea and Calpe sell detailed topographic maps of the area – these are worth buying if you’re planning to do more mountain walking during your stay.
The Sierra Bernia hike is one of those experiences that reminds you why the Costa Blanca is about so much more than just beaches. Just make sure you check the weather forecast before you set off – mountain conditions can be very different from what you’re experiencing down by the sea!
