Surf: Furthest north near San Isidro, is Pacifico, a long, hollow and consistent left that likes N in the swell to stop closing-out. Long walk over the weedy reef lagoon best done in booties. Environment: Pacifico is also a contest site, hosting the North Siargao Surfing Challenge. Up toward Burgos and Alegria is more fringing reef and potential waves and pristine beaches.
