Costa Rica is famous for having "nice" beaches on both its Pacific and Caribbean coasts, but the Guanacaste province on the North Pacific side is the most popular for traditional sun-and-sand vacations. This region, often called the "Gold Coast," features world-class spots like Playa Conchal (famous for its crushed shell "sand") and Playa Tamarindo. For those seeking lush, jungle-backed scenery, the Central Pacific near Manuel Antonio National Park offers stunning white sand and turquoise water. If you prefer a "Caribbean vibe" with turquoise waters and a laid-back Afro-Caribbean culture, the Southern Caribbean coast—specifically Puerto Viejo and Cahuita—is the place to go. In 2026, a high-value peer recommendation is Playa Samara on the Nicoya Peninsula, which is protected by a coral reef, making the water exceptionally calm and perfect for swimming. Whether you want the rugged surf of the Pacific or the tropical mist of the Caribbean, Costa Rica's 800 miles of coastline ensure there is a perfect "blue zone" for every type of traveler.
