Board our charter flight to Petropavlovsk-Kamchatskiy to embark the Sylvia Earle. After boarding, there is time to settle into your cabin before our important safety briefings. This evening, meet your expedition team and crew at the Captain’s Welcome Dinner.

Wake to the wild beauty of Kamchatka’s east coast. Remnant snow fields dot surrounding mountains as we watch for harbour seals in Morzhovaya Bay. We Zodiac cruise the salmon-rich Zhupanova River, dodging rippling shallows to look for brown bears and magnificent Steller’s sea eagles.

Kronotskiy Biosphere Reserve offers stunning (active) volcanoes and Eurasia’s greatest concentration of brown bears, Steller sea lions, fur seals and a range of whales. Keep your binocular focussed for geese, loons and perhaps the spoon-billed sandpiper. Soak in soothing hot springs of Kamenistaya Bay and trek lowlands covered in cottongrass, aspens and birch. As we turn towards the Commander Islands, our team of experts share enthusiastic, informative talks on the adventures that await us.

Spectacular bird cliffs, arches and stacks signal our arrival to the Commander Islands. Pay tribute to explorer Vitus Bering at his grave and memorial. On both land and sea, the wildlife abundance is staggering. At Peregegrebnaya Bay we visit red-legged and black-legged kittiwake rookeries; spot albatross and whales at Cape Monati, and at Ariy Kamen be surrounded by thousands of guillemots. Tufted Puffin Rock speaks for itself. At Nikolskoye village, the Aleut community entertains us with lively performances and a fascinating museum.

We land on the terraced, uplifted coastline of Soldatskaya Bay, and search out endangered seabirds like the long-billed murrelet. At Tymlat village, Koryak reindeer herders and marine mammal hunters warmly greet us with an amazing cultural performance of dance and game that ultimately includes those of us who wish to take part. Time permitting, we get a glimpse of life in one of Kamchatka’s more remote coastal villages.

A Zodiac cruise along Govena Peninsula reveals the broad fjord of Lavrova Bay and the narrower Yuzhnaya Glubokaya where bears often visit the abandoned herring factory. Orcas and Bryde’s whales frequent surrounding waters and an afternoon walk reveals succulent roseroot, magenta-coloured pixie eyes, and cheery purple-blue of Jacob’s ladder and chance sightings of arctic hare. Continue past waterfalls to a glacial moraine and a spectacular vista of the rugged Pylginsky Range.

Wake to spectacular mountains rising above Natalia Bay. Zodiac cruise beneath Bogoslov Island’s cliffs where puffins, kittiwakes, guillemots and cormorants breed and climbing bears raid their nests, while walrus haul out nearby. Hike to hidden alpine lakes and gaze upon the dramatic glacier-carved valleys of Peter and Glybokaya bays. Golden rhododendron and dwarf azaleas carpet the tundra and if you listen carefully, you might hear the song of bluethroat.

Encounter a walrus haulout in Anastasia Bay, also a great spot for birdlife, including bluethroat and Siberian rubythroat. Dezhneva Bay offers a coastal lagoon that’s heaven for birders. Keep your binoculars ready to spot white-fronted bean geese and nesting whooper swans. Other wildlife that you may encounter here include gray whales, walrus, reindeer, and brown bears.
