Sea Excursion to the White Cliffs of Iturup

From land, the White Cliffs of Iturup are already disorienting — a 28-kilometre rampart of blinding-white pumice tuff rising 80–120 metres above the tideline. From a boat running along the base of the cliff in the Sea of Okhotsk, the scale becomes fully legible, and the geology opens like a textbook held at arm's length.

What you'll see

Belye Skaly (White Cliffs) are the eroded edge of a Pleistocene pyroclastic flow — welded pumice and zeolite-rich tuff erupted from northern Iturup's ancestral calderas. The rock is almost pure white, shading to cream and lemon yellow where iron oxides leach through, and so soft you can score it with a fingernail. Wind, rain and Sea of Okhotsk swell have cut it over tens of millennia into organ-pipe fluting, amphitheatre collapses and the slot canyons that are Belye Skaly's signature — dark vertical corridors in a white wall, visible only as the boat passes directly before them.

The boat voyage from Kurilsk takes approximately 90 minutes to reach the southern end of the cliff. We then run north at low speed for 60–90 minutes along the cliff face, giving guests time to photograph and absorb the changing geometry. In coves where lava tongues interrupt the tuff, the beach is a black-and-white mosaic: white pumice ground from the cliff above, black obsidian and magnetite sand from the island's volcanic spine. On clear days the cone of Bogdan Khmelnitsky Volcano appears inland. Steller sea lions occupy rock shelves at the cliff base; Kuril cormorants nest above.

What makes it AMIST

The sea approach to Belye Skaly is the perspective the cliffs were made for. Most land visits require a four-wheel-drive transfer of two or more hours from Kurilsk, timed strictly to low tide, then a walk along the beach with the cliff at your shoulder — spectacular, but foreshortened by proximity. The sea crossing gives you distance, which gives you scale. Our Kurilsk-based launch operators have worked the Okhotsk coastal route since 2014 and read its moods accurately; departures are confirmed on the morning of the excursion based on swell and visibility forecast. We carry the same forecast discipline to the cliff section: we do not run within unsafe proximity to falling rock zones near active erosion faces.

Groups are held to six guests so the boat deck is uncrowded and everyone can reach the rail. We bring telephoto-capable binoculars on loan for the sea-lion shelves and the nest colonies above.

Practical notes

• Duration: 6–7 hours total including transit from Kurilsk: ~90 min outbound boat, ~60–90 min cliff passage, ~90 min return. Departure from Kurilsk harbour 9:00 am; return by ~4 pm depending on conditions.
• Vessel: covered motor launch with open aft deck, capacity 8–10, AMIST operates at 6 guests maximum for this tour.
• Group size: max 6.
• Included: harbour-to-harbour boat charter, experienced local skipper, English-speaking guide on request, field lunch on board, binoculars, border-permit filing for foreign nationals.
• To bring: windproof and waterproof jacket (Sea of Okhotsk spray), non-slip deck shoes, polarising sunglasses (white cliff reflection is intense), a 70–200 mm zoom lens, motion-sickness tablets if prone at sea.
• Season: late June to mid-September. Swell and fog windows are most reliable in July and August. Departure is confirmed same morning; weather cancellation is rescheduled at no additional cost.
• Iturup access: border-zone permit required for foreign nationals (AMIST files 30 working days in advance; passport details at booking). Yasny Airport (BVV), 90 min from Yuzhno-Sakhalinsk.
• Note on land vs. sea visit: AMIST also offers the 4WD land access to Belye Skaly as a separate excursion. Guests wishing both perspectives can combine sea and land on consecutive days.

Why we offer this route

Belye Skaly from the sea is the image that makes travellers return to the Kurils. White rock, grey Okhotsk water, offshore sea stacks and, on clear days, volcanic smoke inland — the combination produces a photograph that looks implausible, which is characteristic of the Kurils. AMIST has offered marine Iturup programmes since the Yasny civilian runway opened in 2014. We limit the group to six so the deck stays quiet and the cliffs stay empty in the frame.
