Amed & Tulamben Snorkeling

The USAT Liberty lies thirty meters offshore in fifteen meters of water, her bow encrusted with soft coral forests that predate most visitors by two decades. The American cargo ship ran aground on Tulamben's volcanic sand in 1942 after a Japanese torpedo struck her hull east of Lombok Strait. Local salvagers stripped her fittings until Mount Agung's 1963 eruption shoved the wreck off the beach and into the shallows, where she settled on her starboard side and became East Bali's most accessible dive site. Snorkelers who arrive early see jackfish and barracuda patrol her superstructure while the surface remains glassy. Amed's seven-kilometer coastline runs north from Jemeluk Bay to Lipah Beach, each cove rimmed by black volcanic sand and shallow reef platforms that drop into blue water within fifty meters of shore. Traditional jukung outriggers ferry snorkelers to sites unreachable by foot: the Japanese Shipwreck at Banyuning, the submerged temple ruins at Jemeluk, and the coral bommies off Bunutan where humphead parrotfish graze on algae. The reefs here escaped dynamite fishing that scarred southern Bali in the 1980s, and water clarity routinely exceeds thirty meters during the dry season. Visibility declines between December and March when northwest monsoon swells stir sediment, but the underwater topography remains navigable year-round. Karangasem Regency's volcanic geology shapes the diving. Mount Agung's 1963 lava flows created the black sand beaches, while mineral-rich freshwater springs bubble through the reef at Jemeluk Bay, attracting schools of fusiliers and triggering algae blooms that feed herbivorous fish populations. The cold-water upwellings that surge through Lombok Strait bring nutrients and pelagic species uncommon elsewhere on Bali's coasts. Reef composition tilts toward hard corals — table corals, staghorns, brain corals — rather than the soft coral gardens that dominate southern Bali's walls. Snorkeling Amed and Tulamben requires no certification, but surface currents strengthen after midday as thermal winds accelerate down Agung's slopes, and tour operators schedule morning departures to avoid the chop.
