A canoe descent on the Sella, rafting below Llavorsí and snorkeling in the Medes Islands reserve each give you a different reason to plan an active day in Spain. Match the activity to your swimming and paddling experience. Several of these outings rely on a provider for equipment, transport or authorized access.
Plan each outing separately. The table compares physical effort; technical difficulty and exposure can differ. Each mission on the map has its location and preparation details.

Choose your time on the water
The Sella is a recreational canoe descent; Llavorsí asks you to paddle as part of a rafting crew. Mont-rebei is a reservoir outing with a fixed return time. Medes snorkeling and Cabo de Gata kayaking depend on organized departures, while independent surfing at Mundaka suits experienced surfers.
Canoe the Sella to Llovio
Launch at Arriondas and take the full recreational descent to Llovio. The route has stopping points at 7, 11 and 16 kilometres and usually takes three to four hours at full length, so you can judge your energy as you go.
Taking the full Llovio option gives you the broadest experience of that valley corridor.
Reserve with an active-tourism provider. The canoe, paddle, buoyancy equipment and return transport are supplied, and swimming ability is required. Departures depend on river and weather conditions.
View in GoExploringRaft from Llavorsí to Rialp
Join a guide in Llavorsí for the classic descent to Rialp. The run includes wave trains, narrow passages and the class-IV La Lavadora rapid, so everyone in the raft needs to follow commands and paddle as a team.
This stretch packs a sequence of distinct rapids into one continuous river journey through Pallars Sobirà.
Use a qualified rafting operator. A guide and specialist rafting equipment are required; the operator supplies the raft, wetsuit, helmet, buoyancy aid and transport. Check current age, flow and departure conditions when arranging the trip.
View in GoExploringSnorkel the Medes Islands reserve
Travel from L’Estartit to the Medes Islands and snorkel inside the reserve with a monitor. The outing puts you directly in the protected marine environment, with the guide helping identify wildlife while you stay off the seabed and leave organisms untouched.
Here, conservation rules and guided interpretation are part of the activity itself.
Use an authorised guided-snorkelling operator. The guide, boat transfer and specialist snorkelling equipment are integral to the activity. Departures are seasonal and depend on sea conditions.
View in GoExploringKayak to Arrecife de las Sirenas
Join the guided sea-kayak route from La Fabriquilla around Cabo de Gata toward Arrecife de las Sirenas. The trip crosses exposed water around the cape and may include a snorkelling stop, so wind and swell determine whether it can run.
The kayak route passes the volcanic cape and offshore rock stacks within the marine reserve.
Arrange the activity with a qualified sea-kayak operator. A guide and specialist kayak and safety equipment are required; the described outing also includes support-boat cover and insurance. Follow the operator’s decision on sea conditions.
View in GoExploringKayak through Congost de Mont-rebei

Collect a kayak near La Masieta and follow the reservoir into the narrow Congost de Mont-rebei. The self-guided outing allows roughly six hours on the water, so you can paddle deep into the gorge and turn around according to your pace and conditions.
Mont-rebei has no road running through its main gorge. Kayaking puts you directly between the rock walls at water level, giving a perspective the cliffside walking path cannot.
Reserve the kayak in advance. The operator supplies the kayak, paddle, buoyancy aid, helmet and dry container, but the independent version has no guide. You need basic paddling judgement and must meet the stated return time.
View in GoExploringSurf Mundaka’s left-hand wave

Paddle out where the estuary meets the Bay of Biscay only when swell, tide, wind and your ability line up. Mundaka is a fast, powerful wave for advanced or expert surfers, with long tubular sections and serious consequences when conditions build.
Mundaka’s river-mouth sandbar shapes a long left-hand breaking wave inside the Urdaibai setting. Surfers come here for that wave.
Independent surfing needs no ticket, permit or guide, but a surfboard and suitable specialist surf equipment are required. Check the current swell, tide and wind before entering, and surf here only if you have advanced ability.
View in GoExploringBefore you set out
Check swimming requirements and included safety equipment before booking. For the Sella and Llavorsí, consider the conditions downstream; for the coastal trips, check wind and current beyond the launch. Keep clear of sensitive habitat and respect the guide or park’s decision to shorten or cancel an outing.
