Marietas Islands
UNESCO Biosphere Reserve with famous Hidden Beach—strictly limited to 116 visitors daily, book 10+ days ahead
Overview
The Marietas Islands are a **UNESCO Biosphere Reserve** famous for the surreal "**Hidden Beach**" (Playa del Amor)—a secluded beach inside a volcanic crater, accessible only by swimming through a short tunnel when tide conditions allow. Located about 35km from Puerto Vallarta in Banderas Bay, these uninhabited islands were used as military bomb testing grounds in the 1900s (which may have created the Hidden Beach crater) before becoming a protected marine sanctuary. Access is **strictly limited to 116 visitors daily**, Wednesday through Sunday only—**the Hidden Beach sells out 10+ days ahead** during high season, so advance booking is essential. Beyond the famous beach, the islands offer exceptional **snorkeling** in crystal-clear waters, **Blue-footed Booby** colonies, and **humpback whale watching** from December through March (peak January-February). Tours cost **$100-200 USD** depending on departure point and inclusions. The **best departure is from Punta Mita** (20-30 minute boat ride) rather than Puerto Vallarta (1+ hour)—shorter ride means more island time and less seasickness risk. Tours also depart from Sayulita and La Cruz de Huanacaxtle. The islands close Mondays and Tuesdays for ecological recovery. Book through licensed operators only—unauthorized landings carry hefty fines.
