Islas Marietas National Park

Islas Marietas National Park sits roughly 45 minutes by boat from the Punta de Mita marina in Bahía de Banderas, Nayarit, and is reached only aboard a permitted tour operator's boat since independent access is prohibited to protect the reserve. A full day should be set aside: 6 to 8 hours covering the marina check-in, the crossing, time on the water, and the return. The islands, an uninhabited volcanic archipelago, are best known for the Playa del Amor (Hidden Beach), a sand-floored cavern beneath a collapsed rock ceiling reachable by a short swim or snorkel from a panga, plus snorkeling sites around Los Anegados and Las Monas where sea turtles, tropical reef fish, and manta rays are regularly spotted. Between December and March the surrounding waters are a migration corridor for humpback whales, and the islands host nesting seabirds such as blue-footed boobies year-round. A typical itinerary departs the marina by mid-morning (8-9am) for the crossing, snorkels or kayaks around the reserve through late morning, visits the Hidden Beach around midday when tour permits allow entry, and returns to Punta de Mita by mid-afternoon. Because the Mexican park authority (CONANP) caps daily visitor numbers and closes Hidden Beach access on rotating days, operators confirm entry the day before. Meals are typically included on tour boats as a light breakfast and a lunch stop, often ceviche or grilled fish served on board or at a beach stop near La Cruz de Huanacaxtle. The best season for calm seas and wildlife viewing runs November through May, with December to March offering the added draw of whale sightings; the rainy season from June through October brings rougher water and lower visibility for snorkeling.
