Again, both. Although, the Pacific Coast has the greatest diversity in beaches. The Northern Coast is the dryest- with beaches backed by dry forest and cacti. As you move south, the beaches get lusher and wilder – with more wildlife.

The "best" side of Costa Rica depends on what you want from a beach: the Pacific Coast is better for variety, surfing, and infrastructure, while the Caribbean Coast is better for "untouched" jungle vibes and snorkeling. The Pacific side (Guanacaste and Nicoya Peninsula) has a much longer coastline with hundreds of beaches ranging from white sand to volcanic black sand. It is drier and more developed, featuring luxury resorts and famous surf breaks like Tamarindo. On the other hand, the Caribbean side (Puerto Viejo and Tortuguero) is more humid and lush, with "boutique" eco-lodges and beaches where the jungle literally meets the sea. The Caribbean water is often calmer and clearer, making it superior for viewing coral reefs, but the Pacific side offers more reliable weather and easier access via the international airport in Liberia. In 2026, the Pacific remains the most popular choice for first-time visitors seeking the "classic" sun-and-surf vacation.
