Aldmeta Diveshop Lembeh is a dive shop in Madidir Unet, Bitung, on the shore of the Lembeh Strait in North Sulawesi, an easy drive from Manado airport.

The team runs guided multi dive day trips by boat, with meals and refreshments served on board between dives so groups can stay out all day. Trips focus on the strait's black sand muck sites, including Nudi Falls and Hairball, where guides find frogfish, nudibranchs, octopus and other rare critters.
