Northern Onekotan beach stretch with remote volcanic-island character and low-density discovery value.
Onekotan South Beach
Southern Onekotan shoreline with remote landing-beach value and strong volcanic scenery.
Onekotan West Cove Beach
Small west-facing cove beach on Onekotan, useful for expedition landing and scenic discovery coverage.
