There are many caves along the coastline from Agia Napa to Cape Greko National Park. Many people come here to snorkel and the locals come here before the crack of dawn to fish. The Palace caves and the Smugglers caves are deep passages in to the cliffs which are only accessible from the sea. Some extend as deep as 240 feet in to the rock. During calm seas and at low tide it is possible to swim and even walk in to most of them. Although they have a rock-strewn environment the waters are wonderfully clear. Boat trips regularly pass by daily. There are spots of deep water amongst the rocks where spirited folks engage in the extreme sports of cliff diving/jumping.
