Huge numbers of the resorts lease or loan snorkeling gear and have beginner classes at their pools.
The ocean preserve encompassing Los Arcos, a rock formation off Playa Mismaloya, is a famous spot for jumping and snorkeling. The bay at Quimixto, something like 32 km (20 mi) south of Puerto Vallarta and available just by pontoon, is a great snorkeling spot. Pangeros situated in Boca, Mismaloya, Yelapa and others can take you to spots less touristy.
On the north side, Punta de Mita has the Marietas Islands, with lava tubes . . .
