I'd start with a nature-led day rather than trying to tick off every beach. Official tourism information names Cerro del Mono, the Public Plaza, Sayulita Cemetery, Paisaje del Rey and beaches including Los Muertos, Kestos and Pátzcuarito among local points of interest. The Hike to Monkey Mountain experience adds a biocultural lens: a guide connects jungle trails, native plants and wildlife with the communities who have inhabited the territory. That combination-place, ecology and local knowledge-is the strongest expression of Sayulita's transition-minded side.
