The municipal Playa de San Juan de la Canal–Arnía route follows a cliff path about 2.7 kilometres long and offers panoramic views of the beach and the Cantabrian Sea. The other paths each have a different focus: some follow the coast, while others run alongside the Arroyo Otero or explore the history and culture of Soto de la Marina.

Beach and Coastal Access

Playa de San Juan de la Canal is a semi-urban, sheltered beach with fine golden sand, strong winds and a wide promenade. It has been awarded Blue Flag status as a bathing beach; check the certification status for the relevant season in advance. Facilities include showers, toilets, a telephone, rubbish bins, a cleaning service, a kiosk and parking. During the season, from 1 June to 30 September, two lifeguards are on duty every day from 11:30 am to 7:30 pm. As facilities may change seasonally, it is a good idea to check shortly before your visit to the beach.

To reach Playa de San Juan de la Canal, take the CA-231 road to Soto de la Marina, then continue along Avenida San Juan de la Canal for another 1.5 kilometres. There is good pedestrian access and parking. A municipal notice dated 26 August 2026 lists 72 free parking spaces at San Juan de la Canal, including two for people with reduced mobility. Parking information may change, so check before setting out.

Coastal Paths and the Stream

The Paseo de Sancibrián runs alongside the Arroyo Otero and provides a safe connection between Sancibrián and Soto de la Marina. It runs from the Molino del Ronzón to the Molino de San Juan de la Canal. Another municipal route, San Juan de la Canal–Virgen del Mar, starts in the park beside the beach. It crosses the canal over a wooden bridge and leads to the opposite bank, from where you can see the Ermita de San Juan de la Canal and the old watermill.

The Arroyo Otero circular route also starts at the tourist information office in Soto de la Marina. It follows paths and footpaths along the stream; along the way, it explains local biodiversity, the medicinal uses of native plants, and how watermills work and their historical significance. The stream is therefore not only a landmark for the routes but also a subject of natural and mill history. The coastal routes and the paths along the Arroyo Otero offer different perspectives, without needing to combine them into one circular walk.

Another guided route is the “Senda de las criaturas encantadas”. It leads from the tourist information office to Playa de San Juan de la Canal. The guides explain Cantabrian mythological stories and the history of Noche de San Juan. The “Camino por la historia viva” circular route explores the history and culture of Soto de la Marina. On “En los albores del tiempo”, the stops include San Juan de la Canal II, El Rostrío and Cueva de La Peñona; the explanations offer insights into Cantabrian life up to the arrival of the Romans.

Mills, Chapel and Coastal Landscape

Soto de la Marina had five historic mills. Among the surviving remains is the 15th-century mill building, Molino de San Juan de la Canal. Its main structure, a masonry dam and a millrace have been preserved. The mill stands at the end of the estuary opposite the Ermita de San Juan de la Canal, at the foot of the cliff rock that extends down to the beach. The Ermita was built by order of Dña María del Pedrajo between 1656 and 1662.

The coastal stretch between San Juan de la Canal and the Marisma de Miengo is included in the Global Geosites catalogue under the name “Dunas de Liencres y litoral de Costa Quebrada”. Landscape and built heritage meet along this stretch of coast. The Torre Palacio de los Castillo - Rusoto y Pedrajo, known as the Liceo de San Juan de la Canal, can also be identified by its architectural details: it has two storeys, two round-arched openings on the ground floor, a balustrade on the upper floor and a family coat of arms. The Iglesia de San Salvador de Vivero stands on a hill; it has three naves, a tiled roof, ten buttresses, and ashlar stone around its doors and corners.

The San Juan Festival

The San Juan bonfire in San Juan de la Canal is recognised as a festival of regional tourist interest. On the night of 23 June, the programme includes a mass, live music, the traditional bonfire and a fireworks display. Programme details may vary. If you are planning your visit around the festival, check the dates and current programme in advance.
