Santander is a compact, easily walkable city built along its bay and the Sardinero peninsula. Most attractions are reachable on foot; for longer trips, the urban bus network (TUS) accepts small dogs in carriers, the FEVE narrow-gauge line connects to Bilbao and Oviedo, the Renfe Alvia reaches Madrid in around 4h30, and Brittany Ferries sails to Plymouth and Portsmouth from the Estación Marítima.
| Mode | Policy | Tip |
|---|---|---|
| TUS (City Bus) | Small dogs in a closed carrier are permitted. Assistance dogs travel free. Large dogs uncontained are not allowed; drivers can refuse. | 💡 |
| FEVE (Narrow-Gauge Rail) | Small dogs in a closed carrier (max 60×35×35 cm) travel free. Larger dogs must wear a muzzle and remain on a short lead; a child's ticket may be required. Useful for the scenic Santander–Bilbao and Santander–Oviedo coastal lines. | 💡 |
| Renfe Alvia (National Rail) | Small dogs under 10 kg in a closed carrier (max 60×35×35 cm) travel for around €25 on Alvia long-distance trains. Larger dogs require advance authorisation and must be muzzled and leashed. Guide dogs travel free. The Alvia Santander–Madrid takes about 4h30. | 💡 |
| Brittany Ferries (Plymouth & Portsmouth) | Brittany Ferries operates two routes from the Santander Estación Marítima to the UK: Plymouth (around 20 hours) and Portsmouth (around 28–32 hours). Pets must travel in a booked pet-friendly cabin, in an on-board kennel, or remain in the vehicle on the car deck (vehicle access during the crossing is limited and pre-scheduled). EU pet passport plus AHC or Great Britain pet entry rules apply. | 💡 |
| Taxi & Ride-hailing | Local taxis are plentiful and most drivers accept small dogs; for larger dogs confirm before boarding. Cabify operates in the city. | 💡 |
Santander's seafront promenade runs almost uninterrupted from the Estación Marítima through the Paseo Pereda, the Jardines de Pereda, around the Península de la Magdalena and along the Playa del Sardinero up to the Faro de Cabo Mayor, around 8 km in total. It is flat, wide, fully dog-friendly on lead, and is the most rewarding way to see the city with a dog.
