The Avacha bay is one of the most beautiful and convenient sea ports. It is rated as the second largest harbor after Guanabara Bay in Rio de Janeiro and is capable of holding the world’s merchant fleet!

Not far from Three Brothers a small piece of land rises above the water. It is Starichkov Island. Its area is about 100 km2. This treeless rocky atoll is a seabird rookery. Every year over 50,000 tufted puffins, guillemots, kittiwakes, cormorants, and seagulls hatch there. This island also provides a nesting ground for a pair of unique Steller’s sea eagles – rare birds listed in the Red Book of Russia. Reefs around are popular among seals and sea otters. In 2003 Starichkov Island became a natural monument.
