Canyoning · Oviedo
How to choose
Both tours run through Asturias with Deporventura and meet at the same point near Las Agüeras, so the choice comes down to intensity and duration. The Cuasacas canyon (50 €, 3.5h to 5h) is rated "Everybody welcome", meaning no prior experience required and the descents stay manageable throughout. The Cascadas de Buanga route (60 €, 4.5h) steps up to "Occasionally sporty", which means more demanding sections, stronger water flows and jumps that require a bit of physical engagement. The 10 € gap directly reflects that added intensity. Pick Cuasacas for a first contact with canyoning in Proaza. Go for Buanga if you want a genuine physical challenge and are comfortable committing to sustained effort in cold mountain water.

Frequently asked questions
What's the most intense moment in these canyons?
On the Cascadas de Buanga route, the sporty sections involving jumps and faster water flows deliver the sharpest adrenaline hits. Cuasacas keeps the intensity more even throughout, which still includes rappels and natural slides in the gorge.
Do you need to know how to swim?
Yes, basic swimming ability is strongly recommended for both routes. Wetsuits and safety equipment are provided, but you will be in moving water for the full duration of the excursion.
How cold is the water?
The rivers in Asturias run through shaded limestone gorges and stay cold even in summer. Operators provide wetsuits precisely because water temperatures in these canyons can be bracing, even during the May-to-September season.
Which tour is right for a first-time canyoner?
The Cuasacas excursion is explicitly listed as "Everybody welcome" and costs 50 €. It runs 3.5h to 5h, giving you enough time to get comfortable with rappelling and sliding without being pushed into demanding physical sections.
Are the tours guided in English?
Yes. Both tours with Deporventura are guided in English and Spanish, so non-Spanish speakers can follow instructions on safety and technique without issues.
