Blue Lagoon

Blue Lagoon looks like a postcard and dives like a treasure hunt. It’s a compact white-sand bay a five-minute boat hop from Padang Bai’s jetty, sheltered from most weather, shallow enough for a first-ever dive — and absolutely crawling with the strange small stuff that makes divers grin into their regulators.

What you’ll find

The bay is a patchwork of coral bommies, rubble, and sand from 3 down to about 22 metres, and every patch hides something: broadclub cuttlefish hovering like hovercraft, blue-spotted stingrays under the ledges, moray eels of half a dozen species, lionfish, leaf scorpionfish in their favourite corals (your guide will know the current residents personally), octopus, and a steady parade of nudibranchs. Night dives here are superb — Spanish dancers, hunting morays, and shrimp everywhere.

It’s not just macro: turtles pass through, schools of convict surgeonfish sweep the bommies, and the sheltered eastern corner holds dense, healthy hard coral. But the honest pitch is critters — this is one of the best places in Bali to learn how to look.

Who it suits

Everyone, genuinely. Dive schools use Blue Lagoon for courses and refreshers because it’s calm and shallow; photographers burn entire cards here; snorkelers can float over the shallow bommies straight off the beach. Currents are usually gentle, though the outer corner can move when the channel is running — stay with your guide and it’s a non-issue.

Practical

• Getting there: Padang Bai is about 1.5 hours from Canggu/Seminyak, 45 minutes from Sanur. Dive boats (traditional jukungs, mostly) load at the harbour and you’re at the site in minutes. The neighbouring sites — Jetty (a brilliant muck dive under the pier’s pylons), Shark Point, and the Ferry Channel — combine into an easy, varied two- or three-dive day.
• Conditions: visibility 10–20 m, water 26–29°C, occasionally cooler when the channel pushes clear water in — which is when it’s at its sparkling best.
• Combine it: Padang Bai is also the fast-boat port for Nusa Penida and the Gilis, so it slots naturally into almost any east-coast itinerary.
