Riumar and the Ebro river mouth (Deltebre)
ViewpointRiumar is the beach settlement of Deltebre at the mouth of the Ebro, about 10 km from Deltebre town, where the river reaches the Mediterranean. From the free car park by the riverside walk, a flat bike and foot path leads to the Mirador del Zigurat, a wooden tower about 12 m high with views over the river mouth, the Illa de Buda, the Illa de Sant Antoni and the Garxal lagoon. Riumar adds a long sandy beach with a promenade, and the river cruise boats leave from piers on the road in. It suits families, cyclists and birdwatchers; skip it if you want an old town or nightlife.

Access and parking
By car: from Deltebre, follow the road towards Riumar (the T-340 in the park’s birding guide) through the rice fields, about 10 km. The Deltebre town guide covers the town itself. From La Ràpita it is 25.5 km in a straight line, but by road you have to go round by Amposta or cross the river at Sant Jaume d’Enveja.
Parking: route 5 starts at a large, free dirt car park next to the Riumar riverside walk (park leaflet). OpenStreetMap also marks two free car parks by the cruise piers on the way in.
By bus: OpenStreetMap shows five stops in Riumar, including the shopping centre and three along the seafront. We could not confirm the lines or timetables.
By bike: the park’s Ecomuseu–Desembocadura route is a flat 31.4 km circuit from the park’s Ecomuseu in Deltebre to the river mouth, about 5 hours.
What to expect
The park’s route 5 takes in the whole area:
- Mirador del Zigurat: a wooden tower about 12 m high at the river mouth, and one of the most popular stops in the delta. It looks over the mouth, the Illa de Buda, the Illa de Sant Antoni and the Garxal.
- Far del Garxal: a 12 m automatic, solar-powered light at the tip of the Garxal.
- Garxal lagoon: two wildlife hides on a dirt track; the second is larger and adapted, for up to 10 people. The park’s birding guide lists terns and waders, often including marsh sandpiper and spotted redshank, and Kentish plovers in the salt marsh.
- Riumar seafront: a promenade with a bike lane and wooden walkways onto the beach.
- Port de Deltebre, home of the Club Nàutic Riumar, a little over 2 km from the mouth, and the Muntell de les Verges, a 4 m river dune with a monument of seven columns.
Illa de Buda: the island across the river, about 1,100 ha of lagoons, reed beds and rice, is one of the richest bird areas of the delta, but access is restricted. You see it from the Zigurat or from the river. On the far bank, in Sant Jaume d’Enveja, the park’s tower over the Migjorn channel gives the best view of Buda.
Boat trips: catalunya.com suggests a boat trip across the river mouth, the Garxal and the Illa de Sant Antoni. OpenStreetMap shows the Las Golondrinas cruise pier and a boat rental, D’Nautik, on the riverbank at the entrance to Riumar. We could not confirm 2026 timetables or prices.
Practical details
- Beach: Platja de Riumar is sandy. OpenStreetMap shows free showers, toilets, beach bars and a picnic area along the seafront.
- Information: OpenStreetMap shows a tourist office in Riumar. The park staffs information huts at the Garxal and the access to Buda at weekends from April to August.
- Camping: Camping l’Aube, east of Riumar, opens April to October according to OpenStreetMap. Wild camping and overnight stays are not allowed on beaches or in the park.

- Drones: hobby flights are not authorised in the delta.
- Events: catalunya.com lists Riumar’s summer festivals on Saturdays in July.
Accessibility and safety
The whole area is flat. We could not confirm step-free access to the Zigurat tower, but the second Garxal hide is adapted, and the promenade has a bike lane and walkways to the sand. The park warns about strong winds for cyclists and advises water, sun protection and mosquito repellent; there is little shade. Keep to the paths around the Garxal, where birds nest on the ground. We could not confirm lifeguard dates on Riumar beach, because the Deltebre and Terres de l’Ebre websites could not be reached.
Best time to visit
For birds, the park recommends early morning and dusk, and the migration seasons. catalunya.com names summer as the best time for the beach and the rice fields; the delta’s gastronomic days run through November. Riumar itself is mostly holiday homes and is quiet outside summer.
