The boat is the way into the Mont-rebei Gorge without paddling or walking the path hanging off the wall. It leaves from the Corçà nautical base, on the shore of the Canelles reservoir, goes up the water until it enters the gorge and returns to the same point: 14 km in an hour and a quarter. It is run by Montsec Activa, the same company that rents the kayaks.

From Corçà to the gorge and back

The boat goes up the Canelles reservoir and enters the gorge, the cut the Noguera Ribagorçana opened in the Montsec and which forms the border between Catalonia and Aragón. From the water you see from below the walls along which the path is carved. The company describes it as a route with no difficulty and suitable for people with reduced mobility.

Times, price and season

It leaves at 10:15. If that boat fills up, they add a second departure at 17:30. It costs €25 for an adult and €15 for children aged 3 to 10; up to age 2 they don't pay. The season runs from March to November: the 2026 one has already ended and, according to its website, it returns on 20 March 2027.

You book on Montsec Activa's website, choosing the date and places, on 636 56 12 04 or by WhatsApp. On the activity page there is a PDF with the route and the Google Maps itinerary to reach the base.

Getting to Corçà

The nautical base is in Corçà, in the municipality of Àger, on the shore of the reservoir; parking is free. On this side there is no road to the gorge: from Àger or Corçà, on foot, you can only enter by the GR-1. That is why the boat is the shortest way to see it if you are coming from the Montsec. If you want to walk the classic path, from the La Masieta car park, see the listing for the Mont-rebei Gorge on foot: it is on the other side and you reach it by car going round via Tremp.

A coat even if it's sunny

A coat, even if it's sunny: on the water and between the walls it gets cool, and the company asks for it expressly. A cap and sun cream too. The company publishes nothing about dogs on board; ask if you are going with one.

Paddle or go up to see the stars

If someone in the group wants to paddle, the kayak through the gorge leaves from the same base, and its trek version returns precisely by boat at 14:30. The 17:30 boat fits with a night of stars: from Corçà to the Parc Astronòmic it is about half an hour by car via Àger.

Tips

  • Go on the morning one The 17:30 only leaves if the 10:15 fills, so don't count on it when planning.
  • With small children It is the way to show them the gorge without the unrailed path: up to age 2 they don't pay.
