Castil Point - Sulawesi

Four Buoy often gets pigeonholed as a beginner site, and yes, it’s a brilliant spot for those just getting their fins wet, but that’s selling it short. We think it’s one of Sodwana's most genuinely fun dives for *anyone* who appreciates a good explore. Dropping down to around 9 metres, you’re straight into a labyrinth of low ledges and sandy gullies. The real draw here is the topography – we love weaving through the swim-throughs and poking into the shallow caves. You'll often find shoals of sweepers tucked away, their scales shimmering in the shafts of light that pierce the gloom. Keep your eyes peeled for the smaller stuff too; we've spotted everything from frogfish camouflaged on the rocks to nudibranchs crawling along the coral. On one memorable dive, a huge loggerhead turtle cruised right over our heads, completely unbothered. It's a relaxed, easy dive, perfect for photographers or anyone who just wants to dawdle and discover.
