Leru Cut, Solomon Islands, is one of my favourite divesites. It is an impressive underwater cave/ deep cut wall which goes under the island for about 100 m at a depth up to 23 m. At the end one can dive up in small pool in the island, surrounded by lush jungle. It really is a stunning site, especially when the sun is out and the sunrays break through the cracks like in the picture. Photography here is challenging because of the extreme light conditions and the deep shadows.
