Blue Lagoon is a small, sheltered cove of about 100 metres tucked beside Padang Bai harbour in East Bali, and one of the easiest snorkelling spots to reach on the Bali mainland. A gentle white-sand bottom slopes into coral-covered walls, and the water is usually calm, which makes it ideal for beginners and families. Its resident blue-spotted stingrays are the signature sighting, alongside clownfish, angelfish, butterflyfish and Moorish idols, with the occasional turtle, cuttlefish or moray eel. As of 2026 it remains a free public beach, and visibility is best in the morning and at high tide.

Can be paired with nearby Tanjung Jepun on a boat tour to cover two snorkel sites in one trip
Good to know
SafetyThe path down to the beach is a steep, rocky set of stone steps that can be slippery. Wear reef shoes or sturdy sandals and watch for rocks and sea urchins when entering and exiting the water.
SafetyIt is usually calm, but the cove opens onto the Badung Strait and currents and chop can pick up, especially in the afternoon. Go in the morning at high tide, stay near shore, carry a float, don't snorkel alone, and if the water looks rough, don't go in — this is a real risk, not a formality even for beginners.
SafetyPadang Bai is a working harbour right next door, so there is boat traffic. Stay inside the marked snorkel zone and keep watching for approaching boats at the surface.
SafetySea urchins, lionfish/scorpionfish and the blue-spotted stingray all carry venomous spines. Look but never touch, and don't stand on the bottom or grab the reef. Even in calm water, defog your mask and breathe steadily to avoid panic.
RulesDon't touch or stand on the coral and don't take any marine life. Use reef-safe sunscreen, and follow your guide's instructions if you join a tour.
MannersKeep your distance from turtles and rays and never feed them. Don't touch or chase wildlife.
SeasonSnorkelling is possible year-round, but the April–October dry season is clearest. During the wet season (Nov–Mar) or after heavy rain the water gets murky, so aim for morning and high tide.
Practical info
Blue Lagoon is roughly a 1.5-hour drive from Kuta or about an hour from Sanur; park in Padang Bai and walk about two minutes down a rocky path to the beach. There is no entrance fee, only local parking and a tip. Boat snorkel tours (Blue Lagoon plus Tanjung Jepun) typically run 3–4 hours, but confirm current prices, times and availability locally, and check that the operator is properly licensed.
