Aldmeta Diveshop Lembeh is a dive shop in Madidir Unet, Bitung, on the shore of the Lembeh Strait in North Sulawesi. The team runs guided multi-dive day trips by boat, with meals and refreshments served on board between dives so groups can stay out on the water all day.

Trips focus on the strait's famous black-sand muck sites, including Nudi Falls and Hairball, where sharp-eyed guides search out frogfish, nudibranchs, octopus and other rare critters. The shop holds a 5.0 Google rating from more than 60 divers, and sits an easy drive from Manado airport via Bitung.
