Karpata was my favorite site of the week! The entry is a little less easy than some of the southern sites but it makes up for it. It was spectacular with its "mountainous" underwater terrain and hugely abundant life. We found a sleeping 7 foot Nurse Shark in-between a couple coral heads. It was awesome to look down the slope and know it just keeps going, almost bottomless. I agree with the "must dive" analogy!
