The gentle clatter of smooth, water-worn pebbles greets you as you step ashore at Polonskogo Island Beach, a secluded gem nestled within Russia's remote Lesser Kuril chain. This Tier 1 beach, boasting an OnlyBeaches Index (OBI) score of 9.5+, is not for the casual tourist but for the intrepid explorer, the nature photographer, and anyone yearning for an authentic, untouched wilderness experience. Polonskogo Island Beach stands out as a vital representation of the northern Lesser Kuril group, offering a glimpse into a truly pristine environment.

The beach itself is a magnificent expanse of polished pebbles, ranging in color from deep grey to muted ochre. These smooth stones make for a unique walking experience and contribute to the water's exceptional clarity. While the waters of the Okhotsk Sea are invigoratingly cool, especially outside peak summer, they are remarkably clean and inviting for a bracing dip. There are no crashing waves here; instead, the sea offers a tranquil, almost meditative calm, perfect for quiet contemplation or a refreshing swim. The surrounding landscape is rugged and dramatic, with verdant slopes meeting the pebble shore, creating a truly scenic backdrop.
