13 Night Cruise sailing from Petropavlovsk to Anadyr aboard Spirit of Enderby.

Run as a co-operative venture with BirdLife International, this unique expedition follows in the footsteps of the Danish Explorer Commander Vitus Bering whose instructions from Tsar Peter the Great were to "sail north by north-east... chart the coast and collect information"

Our journey starts in Petropavlovsk-Kamchatskiy, the city which is named after two of Bering's ships, and we will also travel north by north-east, along what is still one of the remotest coastlines on earth.

Our voyage is dedicated to looking for birds and wildlife and we can expect to have some truly spectacular experiences, however, there is one bird which makes this trip very special and that is the Spoon-billed Sandpiper. This species is classified as 'critically endangered' and it is believed there are now less than 200 pairs which make the annual migration to Northern Kamchatka and Chukotka to breed.

Very few people have had the privilege of visiting this region to see this species and we hope to repeat the success of our previous expeditions when we not only saw birds at Meinypil'gyno, the only monitored breeding site, but also made ornithological history by finding a new population further south

Day 1: Petropavlovsk-Kamchatskiy
Arrive into Petropavlovsk-Kamchatskiy the capital and administrative centre of the Kamchatka Region and board the Spirit of Enderby.

Day 2: Zhupanova River
We plan to spend the morning Zodiac cruising on the Zhupanova River. Our main target here is the Steller's Sea Eagle and there are usually at least three occupied nests close to the river.

Days 3 to 4: Commander Islands
The wildlife-rich Commander Islands were first discovered by the Commander Vitus Bering when his ship was wrecked here in 1741. We intend to explore the islands through a combination of landings and Zodiac cruises and our first stop will be the village of Nikolskoye, where there is an interesting museum.

Day 5: Karaginskiy Island
Our proposed landing site is a patchwork of boggy tundra, ponds and shingle spits and an interesting range of waders can be found here including Pacific Golden Plover, Red-necked Stint and Red-necked Phalarope.

Day 6: Verkhoturova Island and Govena Peninsula
Verkhoturova Island has some huge seabird colonies and by following a short trail to the cliff top we should be able to enjoy some fantastic views of Tufted Puffins, Brunnich's Guillemots, Pelagic Cormorants and Black-legged Kittiwakes.

Later in the day, there will be either a Zodiac cruise or landing on the Govena Peninsula. Good numbers of Brown Bears can often be found here.

Day 7: Tintikun Lagoon and Olyutorskiy Bay
Tintikun Lagoon is one of the most scenic places in the Russian Far East and the lake is surrounded by jagged mountains, glaciers and forested slopes. A shallow river allows us to drive the Zodiacs onto the lake and we intend to make several landings.

Days 8 to 9: Chukotka Coast
We plan to spend two days with members of the Spoon-billed Sandpiper Taskforce searching remote bays looking for unknown populations of this critically endangered species. In 2011 we made ornithological history by locating three territories at a location which had not been previously surveyed. We will be assisting the Taskforce again and hope to repeat our success elsewhere.

Day 10: Bukhta Petra and Bogoslova Island
Another beautiful fiord possessed of a dramatic allure in the low sun of the Subarctic. A walrus haul-out guards the entrance and we make a landing to explore the hinterland, surrounded by imposing mountain landscapes and verdant tundra.

Days 11 to 12: Meinypil'gyno
Meinypil'gyno is located on a 40 kilometre long shingle spit and is the most important site in the world for breeding Spoon-billed Sandpiper, as there are about ten pairs which are monitored by members of the Spoon-billed Sandpiper Recovery Taskforce.

Day 13: Cape Navarin
This coastline is rich in marine mammals and one creature we will be looking for, in particular, is the walrus, as there is a known haul-out. The animals do regularly move between locations, so finding them is always very much a matter of luck, although we have had success here in the past.

Day 14: Port of Anadyr
As we cruise into Anadyr Bay, there is an excellent chance of seeing more Belugas and after a final breakfast on board the Spirit of Enderby, it will be time to disembark.
