The four hiking trails described below can only be done on Ons Island as the entire island of Onza—except its beaches—is classified as a nature reserve. All trails set out from the information booth in As Dornas—beside the pier—, from where you can get information on the routes and other interesting aspects.
The existing paths have made the circular format of all the trails possible and they’re a great way for visitors to get a better appreciation of the natural and cultural values of the island. It is important to heed the signs and all instructions given by the Park’s staff.
