The dive center is located on the other side of the road from the Lumba Resort, so you have to cross the busy Trans-Sulawesi Highway. But the security staff take care of this.
The base has everything you need. Two boats are available: a smaller, faster one travels the 22 km to Bunaken in about 1 hour. The larger catamaran is slower and is used more for the dive sites on the coast north/south of the resort.
Bunaken is mainly wall diving, with lots of shoals, sometimes huge turtles, but also macro. On the coast there is mostly macro, and a wreck worth seeing ("Molas Wreck").
You set off from the resort at around 8.30 am and return after 2 dives, for example at 2 pm. A night dive near the resort can be organized.
