A pretty nice bivouac spot with a view of the Black Sea, mostly sheltered from the sun by the trees. There's a sort of large wooden cabin, but without a roof, so it's not a "shelter," but it adds to the charm of the place. There's no spring, but there's a cemetery in the nearby town (Primorsko).
The place seems very popular with campers and vans because it appears on Park4night, but there are spaces that are only accessible for tents, hehehe.
