Aguas Blancas runs one rafting session on the Esera River, priced at 42 € per person, rated 5/5 across 18 reviews. The trip runs up to a half day and is open to everyone, no experience required. Book early in summer: the Esera runs highest between May and July when snowmelt from the Pyrenees pushes the current hardest. Meet the group outside the 'Cotiella' restaurant in Campo, Huesca, and show up ready to paddle.
The Esera is a Pyrenean glacial river fed by snowmelt, which means fast, cold water and technical rapids, especially in May and June. It's accessible to all fitness levels, but expect a genuine physical workout with real whitewater.
The biggest rapids hit when the current is at its strongest, typically after heavy snowmelt in late spring. Your guide from Aguas Blancas will brief you on each rapid before you hit it.
No prior experience is required. The session is open to everybody, and you'll wear a helmet and buoyancy aid throughout. That said, the Esera is a real mountain river, not a theme park ride.
42 € is the listed price per person for the full session. Confirm any extras such as photos or transport directly with Aguas Blancas at the time of booking.
