Crystal Bay Beach in Nusa Penida, Bali, is renowned for its clear turquoise waters, vibrant coral reefs, and iconic offshore islet, making it a prime spot for snorkeling and diving. Accessibility can be challenging due to uneven paths and steps leading to the beach; therefore, those with mobility issues may find it difficult. While solo visits are possible, guided tours are recommended for snorkeling or diving excursions to ensure safety and access to the best spots. The dry season (April to October) offers the best visibility for underwater activities, while the rainy season (November to March) can bring rougher seas and reduced visibility. Expect to spend approximately $20-$50 per person, depending on activities and transportation. A typical visit lasts 2-4 hours, but longer stays are common for those enjoying water sports or relaxing on the beach. Be aware of strong currents and tides when swimming or snorkeling.
