Its sinuous coasts, 129km long, include other bays such as Tikhaya and Malaya Lagernaya bays. At the North West of the bay are the mouths of Rivers Avacha and Paratunka. At the entrance of the bay rise the “Three Brothers” rocks, a major landmark.
Avacha bay, with its major advantage of not freezing in winter, includes the ports of Petropavlovsk-Kamchatsky and Viluchinsk. It enables ships to take shelter during storms. The waters of the bay have a positive impact on the coast’s climate.
