Aluth Gala

Aluth Gala, meaning New Rock in Sinhala, is a beginner-friendly dive site near Unawatuna on Sri Lanka's southern coast. This relatively recently discovered dive site features a rocky formation that supports a developing marine ecosystem, offering divers the opportunity to observe a reef community in its growth phase. The gala consists of a group of rock formations rising from a sandy bottom, with the structure providing the hard substrate necessary for coral and other marine organisms to establish. The rocks create overhangs, crevices, and small swim-throughs that add interest to the dive and provide shelter for a growing community of marine inhabitants. Coral colonisation at Aluth Gala is progressing well, with pioneer species establishing the foundation for future reef development. Fast-growing branching corals are among the first colonisers, their expanding branches creating additional structure for other organisms to settle on. Encrusting sponges and coralline algae coat the rock surfaces, gradually building the biological base layer from which more complex reef communities will develop. Despite the reef's relative youth, the rocky structure already supports a healthy fish community. Small groupers occupy the crevices, while schools of reef fish including damselfish, wrasses, and fusiliers have adopted the gala as their home reef. Moray eels have found the gaps between rocks to their liking, and octopuses use the formation's nooks as hunting bases. The sandy surroundings provide additional interest, with garden eels, burrowing gobies, and the occasional ray adding to the dive's species list. The combination of developing reef and open sand creates a diverse diving experience within a compact area. The beginner-friendly rating reflects the shallow depth, gentle current conditions, and easy navigation around the formation. Visibility ranges from 8 to 15 metres during the optimal northeast monsoon season from November to April. Water temperatures remain a comfortable 27 to 29 degrees year-round.
