Karpata was my favorite site of this trip, with the best visibility and reef. The topography is interesting and the fish and plant life together were excellent. The road to Karpata is narrow but quite passable. There is ample parking and the entry is accessible down a few stairs. At the bottom of the stairs there is a concrete platform where one can sit to don fins and masks. With snorkel or regulator in your mouth, roll on your belly with an outgoing wave and kick away from the entrance. Conditions were rough when we were there so we exited by kicking on to the platform with an incoming wave, then crawling a ways to remove fins. In better conditions, it likely would be possible to swim very close to the platform, remove your fins, and walk out.
