Kudahrah Thila

Kudarah Thila is a small, steep-sided pinnacle, barely 100m across, ringed by overhangs, clefts and swim-throughs. Most dives drop fast and negative onto the rock so the current does not push you off before you reach the reef. From there the dive splits two ways. In slack water you circle the full perimeter, drifting under the overhangs and through the swim-throughs while soft corals and snapper schools slide past. When the channel runs, the dive concentrates on the corner where the current splits.

That corner is the reason most divers come. You tuck in with a reef hook and hold position, and the foreground fills with bluestripe snapper and fusiliers while grey reef sharks patrol the deeper blue. An eagle ray sometimes joins them. After ten minutes or so on the sharks, the back half of the dive is the soft-coral tour, working the overhangs with the fish unbothered by your presence, before lifting off into a drifting blue-water safety stop off the thila.

Among South Ari's thilas, Kudarah earns its name on three counts. The first is structure: clefts, caves, swim-throughs and an archway packed onto one compact pinnacle, varied topography in a single dive rather than a long reef swim. The second is colour. Pink and orange soft corals, black coral and large sea fans drape two big overhangs, which local operators rate the prettiest in the archipelago. The third is the shark corner, the part divers travel for. When the channel runs, you tether at the split point and the grey reef sharks hold in the blue while you watch.

The long protection underpins both halves of the dive. Designated in its own right since 1995, the rock has carried protected status across two regimes, and it shows. The corals are healthy and the fish are tame. One diver described them encircling the group as if the divers were part of the school, which is the rare gift of a site where the life has stopped fleeing.

Bring the wide-angle. The signature frame here is a soft-coral overhang, fans and black coral in the foreground with a wall of bluestripe snapper behind, and the compact pinnacle puts those elements close together. The two large overhangs are the obvious set pieces, draped in pink and orange and best shot looking up into the light.

The current shapes the shoot. On the running days the snapper bunch tight and the sharks come in at the corner, but you are working from a hook and holding position, so settle your trim before you raise the camera. On slack days you can move freely around the structure and take your time under the overhangs. Either way, hover and stay off the corals; the soft corals and sea fans are fragile and the whole point is that they have been left alone.

A reef hook is standard kit. The corner is the highlight and usually needs one, and negative entries are the norm when the current is incoming. Descend promptly so you are not carried off the small pinnacle before you reach the reef. Carry an SMB for the drifting blue-water safety stop, which often finishes off the thila rather than on a shallow shelf. The caves and swim-throughs are short overhead sections, so stay within your training and hold your buoyancy clear of the walls. The site is reached only by boat, about 20 minutes from Dhangethi, with local-island and resort operators running it. Plan it as the deeper first dive and keep an eye on air and no-deco time on the 30m perimeter.
