It's fantastic that you want to come and ride in Ainsa. Unfortunately, as of June 1st, 2024, I am no longer a mountain bike guide because I am pursuing my dream of building the Life-Centered Design School, my other business. Below, you'll find my recommendations for riding in Zona Zero Pirineos.
I highly recommend Martin Campoy as a guide. If you need a rental bike, visit Cinca Riders for top-spec e-bikes. If you need help climbing the mountains, call Trail Hunters for shuttles to the best trails.
If you are looking for a place to sleep, consider Bed & Breakfast Dos Arcos in Usana. If you want a local experience in a small village just outside of Ainsa, they make fantastic breakfasts with homemade cakes from Emma, and Yiftach runs his bike repair shop from the bed and breakfast. If you want all the comfort of a modern hotel, stay at Hotel Dos Rios in downtown Aínsa.
Enjoy your stay in Zona Zero!
