Playa San Juanillo
San Juanillo's double coves feel like a secret handshake—tucked north of the Ostional chaos, buffered by dry forest, and flanked by volcanic rock that turns rust-orange at sunset. The sand squeaks underfoot, and the snorkeling off the southern point rivals anything you'd pay for farther north.

Questions people actually ask about Playa San Juanillo.
Is Playa San Juanillo good for swimming and snorkeling?
Playa San Juanillo's twin bays typically offer calmer waters than many exposed Pacific beaches, making them suitable for swimming during favorable conditions. The white sand and turquoise water create an appealing setting for water activities. Snorkeling can be rewarding around the rocky areas between the bays and near the points, where you may see tropical fish and marine life. Conditions vary with tides and season, and there are no lifeguards, so swim cautiously. Bring your own snorkel gear as rental facilities are limited in this area.
When is the best time to visit Playa San Juanillo?
December through April offers the best weather with consistent sunshine, calm seas, and minimal rainfall, ideal for beach activities and snorkeling. Even during this high season, San Juanillo remains relatively uncrowded compared to more famous Guanacaste beaches. For maximum solitude, visit on weekdays or during shoulder months like November or May. The beach's white sand and turquoise water are most striking in bright sunlight. Green season from May to November brings occasional rain but also lush surroundings and even fewer visitors.
