Ringed by mountains and situated in an ancient volcano crater, Kurilskoye Lake is one of Kamchatka's most special destinations. Stay in a quaint, wooden lodge on the lake's shores and take part in some of the best bear viewing on the peninsula. Watch the massive pink salmon run and take walking excursions on the lake to view Stellar sea eagle's nesting.
After the bears of Kurilskoye Lake, you'll continue the trip on geology and volcanology on the plateau of Mutnovsky Volcano. At the end you can take a spectacular helicopter flight north of peninsula visit the famous Valley of Geysers and caldera Uzon volcano.
Day 1
Arrival in Petropavlovsk-Kamchatsky. Transfer from the airport to a hotel. Prepare for the trip. Welcome dinner in a city restaurant.
Day 2
Flight by MI-8 helicopter to Ksudach Volcano (1hr). Make an excursion to the crater lake of Schtubelya (situated inside Ksudach Volcano) and visit a lovely waterfall where water cascades out of the crater. Visit hot springs that create a "hot beach" on the lake's shore. Short flight to Kamchatka's famed Kurilskoye Lake.
Accommodation in a small cozy wooden lodge on Grassy Point. The lodge is two stories with 2 bunk rooms of 5 people each on the second floor. One, 5 person bunk room and a dining room are situated on the first floor. A "wrap around" deck affords a gorgeous view of Kurilskoye Lake and surrounding mountains. Often it is possible to watch bears fishing along the lakeshore without even leaving the territory of the lodge. Make an excursions along the lake's pumice rock beach. In-camp instruction.
Days 3-4
Watch Kamchatka brown bears, Stellar sea eagles, salmon spawning places.
Take motor boat excursion and walking excursions with local wardens to a nearby bear view platform (250 meters from the lodge) that is located at the mouth of the many rivers that drain into Kurilskoye Lake.
Here you'll have a good chance of taking great, close-up shots of bears fishing for migrating salmon. The salmon pause briefly in the lake and then make their way from the lake into the streams where they spawn. Take longer walking excursions to a large meadow where bears feed on wild berries and visit other spawning streams farther from the lodge. Along these streams you'll see spawning salmon and many signs of the large number of bears in the area. There's a good chance you'll see bears fishing just a few yards away as you walk along the banks of streams.
Take walking excursions with local wardens to a nearby bear view platform (250 meters from the lodge).
Evening helicopter MI-8 flight to stop for a bathe in the thermal hot water of the Khodutka River. This is the largest wild hot springs on Kamchatka. The water bubbles out on a section of tundra located just under Khodutka Volcano and forms a small stream. Farther from the source the water slowly cools and you can find the location where the temperature is right for you to take a swim.
Helicopter lands near tent camp on Mutnovsky Volcano plateau, where our 4 or 6WD truck and Russian team will wait for you. Accommodate in tent camp.

Breakfast. Have an anorak, extra sweater and woolly hat on, or in a day bag. Food is not needed. A water bottle is useful for your own drinking supply. Leave everything else in your tent and set out for Mutnovsky volcano trek.
The volcano walk is on a single trail there and back, and everyone should walk into the caldera. Wandering off alone is seriously discouraged, as snow bridges, ice falls and unstable ground on geothermal crusts all provide hazardous environments.
• From the Osvystannye campsite, the walk is nearly 7 km, with a rise of less than 600 m, into the main caldera. A gentle stroll soon starts to climb steadily on the bedded pyroclastics of the Mutnovsky slopes beside a stream which emerges from the caldera exit gorge ahead.
• Beyond the track, a foot-trail climbs past more old bore holes spouting steam, to the pass between Mutnovsky and Dvugorby, from where Asacha (left), Opala and Gorely (right) are seen ahead.
• The route then makes a long traverse of the hillside, on a mix of rough tundra, blocky andesite lava and banks of airfall ash and pumice reworked by the wind; it crosses three broad snow-fields, before a final rise to the mouth of the caldera exit gorge.
• The two routes meet above a short descent into the gorge. Above the steep wall to the south, the steam plume can be seen rising above the active crater of the volcano. Seen away to the east, there are cinder cones and tuff rings over flank vents on the Gorely slopes.
The Mutnovsky 3 caldera

• The walk up the gorge is largely on banks of hard snow and firn ice, that has accumulated in winter avalanches off the gorge walls.
• A steep scramble aided by rope handlines leads up coarse welded pyroclastics to a knife-edge ridge between the caldera and the active crater. The steam plume from the active crater rises far above, but when the wind blows it around, the vigorous fumaroles and solfataras that are its source can be seen on the crater floor. The crater is about 350 m across, and its walls drop nearly vertically for over 100 m to its flat floor of scree and inwashed ash.
Return to the campsite back along the outward route. Dinner at camp. Accommodate in tent camp.
Breakfast. Pack your overnight bag and sleeping bag, and roll up your camp-mat, and put them all in the vehicle before setting out for the day's walk. Have an anorak, extra sweater and woolly hat on, or in a day bag. Food is not needed. A water bottle is useful for your own drinking supply.
Gorely volcano trek
Again the volcano walk is on a single trail there and back, where members can walk as far as they wish and then return down the same trail. Avoid walking alone; in case of accidents as trivial as a sprained ankle, it is best to be in groups of at least three.
From either campsite, the 6WD bus head north to the track round the edge of the large lake that lies in the unfilled eastern crescent of the Gorely caldera.

• From the lake flats, the walk up the volcano is about 5 km, climbing steadily to gain 750 m in height. The walk up the huge shield volcano is over a mixture of rough grassy tundra with very low dwarf willow and bare stripes of basaltic a lava. Some lava flow structures are recognizable, and there are also patches of volcanic ash redistributed by the wind.
• Aim up the slope for the saddle between the two low summits which are the raised rims of separate craters. Higher up, long gently graded snow-fields provide the easiest route up (and certainly the best way to come back down). The southwest crater, to the left, is dead and rather featureless.
• Continue beyond it to a broad shelf that extends inside the very large old central crater. Picnic lunch on the shelf. Just ahead, there is a sudden, unguarded, vertical descent into the active crater.
• Over 100 m down, a hot acidic lake has active fumaroles and solfataras around its margin and beneath the surface. The recent eruptions of Gorely have been largely steam events produced when these vents heat up and therefore increase their output.
• Return back along the outward route to the bus by the lake. The bus head back out of the Gorely caldera, and then return to a hotel in the Paratunka Valley. Rest and swim in pool with thermal hot water.

Breakfast in hotel. Leave in a conventional bus, for the journey back to Petropavlovsk. Bring all your baggage with you.
• Have a boat excursion in Avacha Bay, which will be a very relaxing way of gaining an alternative view of the splendid setting of Petropavlovsk and its dramatic volcanoes. Departing from a pier near the center of town, the expanse of the hilly city soon falls into perspective. Further toward the middle of the bay, both Koryaksky and Avacha volcanoes come into view behind the city.
Avacha Bay is geographically as perfect a bay as a city could hope for. It is large and deep, with a narrow opening which keeps out foul weather and ice. . The cliffs around the bay house many colonies of seabirds in their natural habitats, and puffins are commonly seen among many other types of seabird.
• Hot lunch is aboard. Visit the Volcanology Institute.
A visit includes a short video and presentation by one of the volcanologist to outline the volcanic features of the Kamchatka peninsula. There is opportunity to see the small museum, with its spectacular photographs of most of the volcanoes.

Optional helicopter excursion to the Geysers Valley and caldera Uzon volcano.
Breakfast in hotel. Leave your things in your room, as we return in the evening. Wear boots and outdoor gear. Have rain gear and a spare sweater in a day bag; no food is needed; keep clutter to a minimum as it will only be a pain in the helicopters. Leave in our own conventional bus, for the 45 minutes drive to the heliport, at Yelisovo, close to the main airport.
The helicopter flight to the Valley of Geysers takes about 75 minutes.
The Valley of Geysers
The cluster of geysers, fumaroles and hot springs in this valley were only discovered in 1941. The valley's geysers include a few with large but brief periodic eruptions, and many more which produce hot water spouts frequently or almost continuously.
The helicopters land in front of the timber lodge that is the access point for all visitors to the trails into The Valley of Geysers (Dolina Geyserov), within the Kronotsky Nature Reserve. Walkabouts in the valley are not allowed, so we will stay in a group.
The boardwalk leads to the lip of the valley for a fine overall view. The upper slopes of the valley expose cliffs of pumaceous tuffs, some eroded into earth pillars.
A branch to the left ends at the Bolshoi (Big) and Maly (Small) Geysers. An eruption of Bolshoi, on the left, throws water about 10 m high amid clouds of steam, for about 10 minutes; it erupts on a cycle of about 75 minute. Maly Geyser throws water out at 45° for about 8 m, in eruptions lasting 5 minutes on a 35 minute cycle.
The main path descends to a bridge over the Geysernaya River a little further upstream. The river reaches a temperature of 26°C with its geothermal input in the summer; winter snow-melt reduces it to about 16°C. Water from the springs and geysers varies from 35°C to 100°C. Just upstream of the bridge, the Schell (Crack) Geyser erupts briefly every 35 minutes; it was heavily eroded during a typhoon flood in 1981.
The boardwalk ends before another old bridge. Velikan (Giant) Geyser is on the far bank, inside the bend of the river; it erupts with a cascade of water to heights of about 25 m, but only for about a minute, before sending steam jets to far greater heights for another few minutes; its cycle is around 8 hours. Lunch is scheduled at the Valley of Geysers lodge.Weather permitting, continue the helicopter flight to the caldera of Uzon.
The Uzon Caldera
The Uzon depression is bordered to the north and west by steep caldera walls that have survived into the modern landscape. These are essentially features of the second in the series of three caldera collapses; the third (minor) collapse merely deepened the depression west of the heli pad that is now largely marsh ground and lake remnants on a floor of lacustrine sediments. Immediately west of the heli pad, Bannoe Lake has a steam vent beneath it; this erupted in 1989, but is now quiet. The lake is about 30m deep, and its bottom 7m are a pool of liquid sulphur at a temperature of 140°C; large blocks of glassy black sulphur have been extracted by volcanologists. It appears that the sulphur vent is similar to the black smokers of ocean floors.
Return by helicopter to Yelisovo, and by bus to the Petropavlovsk Hotel. Dinner in hotel.
Breakfast and departure from Kamchatka.
