Lembeh is one of the world's muck diving havens. Lembeh's volcanic sands are home to an amazing variety of strange macro creatures. This includes all kinds of small fish, seahorses, cephalopods, sea slugs, crustaceans, etc. It is a great place for macro photography, where you can observe marine life and animal behavior up close.

The dive sites generally have either black sandy bottoms or coral reefs. Because the dive sites are all within a sheltered strait, the surface conditions are very easy and travel time to get to the sites is short. This makes the diving very easy and not strenuous. Most sites are relatively shallow, allowing you plenty of bottom time.

Overcrowding has become an issue in recent years. The dive operators have done quite a good job of self-regulation, with a maximum of 3 boats allowed at any one dive site (if you are the 4th boat to arrive, you have to head elsewhere). Also, the mandarinfish dives are highly regulated with a maximum number of divers allowed at any one site.

There are plenty of resorts in Lembeh to suit all tastes and budgets, from high end villa/spa resorts to family friendly and budget offerings.

What Lembeh is not so good for:
- Large animal life. Most of the marine life in Lembeh is quite small and best suited to macro photography.
- Topside activities. There is not a lot to do for non-divers.
- While the area is quite picturesque, the waters are filled with litter such as plastic bags, snack wrappers, plastic bottles, metal cans, etc.
