The boulders are very cool. The only thing is that the plates are slippery when entering the sea from algae, you need to be extremely careful not to hurt your feet. The water is certainly dirty.. It is very warm in summer.. But this is a bay, so what to expect. If you want clean water, you need it on the Gene slide.. Or Strelkovoe, Shchastytsevo.. The further along the Arabat arrow, the better.
