While the Togeans are popular with beach lovers and snorkellers, it is the diving here that gets the best reports.
As with snorkelling, some of the reefs are in quite poor condition thanks to cyanide and dynamite fishing, but the more isolated and deeper sites do serve up good conditions.
Particularly noteworthy is the wreck of a B24 Liberator bomber that ditched on the south coast of Pulau Togean (about a 30 minute speedboat ride from Kadidiri Paradise). The wreck's highest point is at around the 17-metre mark so this is unfortunately too deep for snorkellers and Open Water Divers, but it can dived by Advanced Open Water divers or as an Adventure Dive. Note that the waters that the B24 lie in can suffer from low visibility, but when clear it is apparently a very enjoyable site.
To the west of the archipelago it's all about steep drop off dives -- some of the walls off Taupan apparently plunge more than 200 metres -- with numerous atolls and shallows well worth exploring. This is the area we learned to dive in and highly recommend it -- not just for the scenery and aquatic life (a highlight included an eagle ray and devil ray at the atoll) but also for their isolation. You're almost guaranteed to have whichever site you visit to your group alone.
