Outdoor Activities in Biscay

Biscay’s landscape is incredibly varied, making it an ideal destination for a wide range of activities. From ocean sports to forest hikes, there’s no shortage of things to do in Biscay for nature lovers and thrill-seekers alike.

Surfing the Basque Coast

The rugged Biscayan coast is known for its powerful waves and stunning surf beaches. Sopela, Bakio, and Mundaka are world-renowned surf spots that attract both beginners and experienced surfers. Mundaka, in particular, is famous for its legendary left-hand river mouth wave, considered one of the best in Europe.

For those new to the sport, surf schools in Sopela and Bakio offer lessons and equipment rentals. On calmer days, these beaches are also perfect for stand-up paddleboarding.

Hiking and Nature Walks

Biscay is home to some of the most scenic hikes in northern Spain. The Urkiola Natural Park, located in the interior, offers limestone peaks, lush forests, and panoramic viewpoints across the Basque hills. Popular trails include routes to Anboto Peak or Atxarte Valley, with options suitable for all fitness levels.

Closer to the coast, the walk to San Juan de Gaztelugatxe is a must-do. This dramatic islet, connected to the mainland by a winding stone bridge, provides a short yet steep hike with unforgettable ocean views. The area around Barrika and Getxo also offers excellent cliff walks and coastal trails.

Sea Kayaking and Coastal Exploration

Explore Biscay’s coastline by sea kayak for a unique perspective of its cliffs, caves, and fishing villages. Kayaking around Gaztelugatxe or along the Urdaibai Biosphere Reserve lets you discover Biscay’s natural beauty in a peaceful, eco-friendly way.

The Urdaibai estuary, a protected UNESCO Biosphere Reserve, is ideal for paddling and birdwatching, especially during migratory seasons. The calm waters are also great for beginners and families.

Climbing and Via Ferrata

The limestone formations in the interior of Biscay, especially near Atxarte and Otxandio, are popular with climbers. There are well-maintained sport climbing routes for all levels, and some areas offer via ferrata for a mix of hiking and vertical adventure with the added safety of fixed cables.

Paragliding and Aerial Adventures

Biscay's coastal cliffs offer excellent paragliding opportunities. Sopelana is the main launch point for tandem paragliding flights, where you can soar above golden beaches and turquoise waves. Inland launch sites offer flights over green valleys and mountain ranges, one of the most original things to do in Biscay for a bird’s-eye view of its wild terrain.

Local Tips for Outdoor Adventures in Biscay

Biscay's maritime climate means it stays green year-round but can change quickly, pack layers, waterproofs, and sun protection. For surf and kayak activities, wetsuits are usually included in rentals, but always check in advance.

Public transport in Biscay is excellent. You can reach Sopela, Bakio, and Mundaka by metro or bus from Bilbao, making it easy to enjoy coastal adventures without a car. However, renting a vehicle offers more flexibility, especially for exploring the mountains or natural parks.

After your adventure, don’t miss the local food. Biscay’s cuisine is rooted in the sea and land, think grilled fish, bacalao a la vizcaína (salt cod in red pepper sauce), marmitako (tuna stew), and of course, Basque cider or txakoli wine.

Best Time to Visit Biscay

Outdoor activities in Biscay can be enjoyed throughout the year, though each season brings a unique flavour.

Spring (April to June) is perfect for hiking, cycling, and kayaking. The countryside is lush and full of life, and trails are quiet. This is also a great time to spot migratory birds in the Urdaibai Reserve.

Summer (July to September) is the best time for surfing, beach days, and paragliding. The weather is warm and dry, and coastal towns like Bermeo and Lekeitio are lively with cultural events and local festivals.

Autumn (October to November) is a peaceful season for hiking and inland excursions. Forests turn golden, and the weather remains mild. The sea is still warm enough for surfing, and the waves begin to pick up.

Winter (December to March) sees fewer visitors, but the coast remains active with bigger surf and empty line-ups. Inland areas offer moody, atmospheric hikes, and it’s a great time to discover Biscay’s culinary and cultural side.
