Bareyo has the sea, marshes, and the Camino del Norte running through the municipality — but it's also perfect terrain to explore on two wheels. Between Ribamontán al Mar, Ribamontán al Monte and the villages of Trasmiera, rural tracks, dirt paths and quiet secondary roads add up to several mountain bike routes without straying far from the villas.
We've gathered four real routes from the area, from easiest to hardest on a scale of 1 to 5 — none in this radius reaches a 5, the toughest tops out at a 4. Two coastal routes, one inland route with more elevation gain, and one loop that combines road and track. You can check trail conditions and more variants in Turismo de Cantabria's cycling route guide. At the end, which routes work best if you're travelling with children.
From Güemes to Bareyo via the Ermita de San Roque
Difficulty: 1/5. This route links Güemes with Bareyo along rural tracks and quiet secondary roads, passing the Monasterio de Nuestra Señora de Latas, the church of San Vicente Mártir in Güemes, and the 17th-century Ermita de San Roque — the same chapel that features in our Santa María de Bareyo hiking route. It's a little under 16 kilometres from Güemes to the chapel, with a final stretch that crosses the Campiezo river before entering Bareyo. The terrain is almost entirely flat with no technical difficulty, making it a good first ride for anyone new to mountain biking in the area, or for going out with kids who already handle a bike confidently.
The coastal path of Loredo, Langre and Galizano
Difficulty: 2/5. The path that skirts the cliffs between Loredo, Langre and Galizano is the most photogenic of the four: it starts at Loredo beach, crosses pine woods and meadows up to the cliff ridges overlooking Isla de Santa Marina, then drops down to Langre beach and the cove at Galizano. It's suitable for all levels except a couple of short stretches right at the edge, where it's best to get off the bike and walk. The climb is gentle but steady — nothing your gears can't handle — and the views make up for any short rise.
The Ribamontán al Mar and Ribamontán al Monte loop
Difficulty: 3/5. This 22-kilometre loop runs through both Ribamontán municipalities — al Mar and al Monte — on a route local cyclists describe as a leg-breaker: no big climbs, but short, repeated rises that add up in your legs by the end. It works on both a mountain bike and a road bike, since much of it runs along quiet asphalt. The real thing to watch for is traffic: in summer and on weekends the area fills up with cars, so it's worth riding with lights and a reflective vest even in daylight.
From San Mamés de Meruelo to the Alto de San Martín
Difficulty: 4/5. The toughest of the four starts in San Mamés de Meruelo, climbs to the Fuente de los Tejeros and the Alto de San Martín, and descends into Güemes — the stretch with the most accumulated elevation gain in this whole radius. There are dirt tracks with the odd technical section and consecutive climbs that call for trained legs; in return, the summit gives you a view over much of the Trasmiera coast in one glance. It's not a route to start out on a mountain bike, but it doesn't take a competitive level either — with a mountain bike in good condition and some prior riding experience, it's manageable without undue suffering.
Cycling with kids near Bareyo
For riding with the youngest ones, the Güemes-to-Bareyo route via San Roque is the safest choice: flat, short, and along low-traffic tracks. The first stretch of the Loredo, Langre and Galizano path — up to the cliff ridges, before the technical descent — also works well if the kids already handle a bike on uneven ground, always with an adult leading the pace ahead. We'd leave the Ribamontán loop, because of the car traffic, and the climb to San Martín, because of the elevation gain, for when the kids are a bit older.
What you need to know
Best season: April to October, with less mud on the dirt tracks and longer daylight to finish the longest route. Bike: MTB or gravel for all four routes; the Güemes-to-Bareyo route and the Ribamontán loop can also be done on a road bike if you avoid the dirt stretches. Water and shade: none of the four has water sources along the way, and the coastal ones have barely any shade. Traffic: on the Ribamontán loop, wear a helmet and use lights even in daylight on the road sections. Tides: they don't affect these routes, unlike the area's hiking trails, which run inland or along the top of the cliff.
You don't need to be a competitive cyclist to discover Trasmiera by bike. With a decent mountain bike and a willingness to take it slow, the scenery does the rest.
Four routes, four paces, none more than half an hour's drive from the villas — the same Trasmiera we covered on foot in our hiking routes near Bareyo guide, this time on two wheels.
Bareyo Residences sits at the heart of this district, with Ribamontán al Mar and the rest of Trasmiera just a pedal away. The villas will be available to book from September 2027.
