FREE things to do in Laredo, Spain

Laredo is one of those places that instantly wins you over. Tucked along the stunning Cantabrian coast, this medieval town has a quiet charm—and a surprisingly impressive claim to fame with the largest marina on the Cantabrian Sea. We spent two slow, sunny days wandering its streets, soaking up the atmosphere, and hunting down all the best things you can do here without spending a single euro!

Iglesia de Santa Maria – Church

Located at the top of the town is the beautifully restored Romanesque church dating back to the 11th century which was declared a National Historical Artistic Monument in 1931. The surrounding area is really unique surrounded by the fortified wall and Civil War monument. It isn’t large by Catholic church standards, but the details are exquisite and the altarpiece was one of our favourites throughout our Spanish trip. Entry is FREE but there is a donation box at the entrance if you wish to support the church.

La Puebla Vieja

The old town comprises of six main streets that are easily walkable. It’s one of those places that you don’t need an itinerary, we loved getting lost as we wandered through the streets.

Start with the medieval narrow stone streets, you will pass under old archways, stumble along tiny plazas, and catch a glimpse of the sea between rooftops. We enjoyed chatting to the shop owners and watching the locals go about their daily life.

Along the six medieval streets you’ll find Casonas (large noble houses), Palacios (palaces) and Casas-torre ( tower houses). Be sure to stop by Casa de los Peregrines which is a beautifully crafted historic residence and known as one of the most elegant civil buildings in Laredo.

El Tunel

Located at the eastern end of town is a 220m tunnel that connects the town area to the beach and features some amazing artwork by local artists. It was originally designed to reach a port that has since been destroyed but interestingly was used as a refuge during the Spanish Civil War. At the end of the tunnel, we were rewarded with stunning views of the coastline and some locals enjoying a spot of fishing. Part of the area has fenced railings, but you can also climb down onto the rocks on a calm day.

The tunnel is open from 7am-10pm daily.

Playa La Salve

This is a stunning beach with crystal clear waters and golden sand that spans 5km. We visited in September so it wasn’t warm enough for us to swim ( yes, we like it super-hot before getting into bathers!) however we did spot free showers near the grassed area. We enjoyed walking along the well maintained 5km promenade which is easily wide enough for both walkers and bike riders. There are also some interesting monuments including plaques and structures honouring the city’s maritime and Hanseatic history and a children’s playground.

Stunning views from the climb at Fuerte del Rastrillar

Fuerte del Rastrillar

After a short but uphill climb with some stairs we were rewarded with sweeping views of La Salve Beach and Santona Bay which make for a great photo opportunity. As for the fort, featured are three buildings which appear to be reconstructed but empty so not sure if future plans exist to turn this area into shops/ function centre etc. We also explored some military remains including trenches and batteries. The main access route to the cliff path is from behind the church with a one-way system so make sure you retrace your steps to get back to town (we did get lost a few times but that just added to the fun!).  We recommend accessing the path via the walkway to the east of the church as it’s much more scenic.

Exploring Laredo doesn’t have to cost a thing, and that’s part of it’s charm.
