Easily accessible island walls in front of Hanko shores. Often deep water to dock your boat just in front of the boulders. The rock type is atleast good, sometimes amazing granite! The problems vary from low to highballs, mostly on 5th and 6th grade. Routes are usually clean by nature and will probably stay clean even without visitors. Remember the wave size can be big in front of Hanko and anchoring can get challenging so practise it well before heading out there!
Remember to check if there is any military practise going on in the sea before going offshore.
Also be careful not to touch any ammunition if you find some old practise material from the islands!!
