Bali sits at the heart of the Coral Triangle the most biodiverse marine region on the planet. What this means in practice is that snorkeling in Bali is extraordinary: manta rays at Nusa Penida, an intact coral garden at Blue Lagoon, a World War II shipwreck at Tulamben you can reach by swimming from shore, and the rare ocean sunfish (mola mola) at Crystal Bay during September and October. The island has options for every ability level, every budget, and every schedule from a half-hour swim off Sanur’s beach to a full-day offshore expedition.
This guide covers the best snorkeling spots in Bali, what to expect at each, how much it costs, and how to reach them from Sanur. For day trip logistics, our guide to day trips from Sanur covers the full range of options including the island day trips where the best snorkeling happens.
