The northern coast of Zante is littered with caves and sea eroded cliffs and the Blue Caves at Cape Skinari and are one of the best-known sights on the island. The largest cave is called the Blue Grotto and the colour here really is spectacular.
Best is the Kianoun Cave which bathes in a light of shimmering blue and best viewed in the early morning. Readers recommend arriving early and taking one of the smaller boats that sail inside the caves.
The area is popular for snorkelling, not only because of the intense blue hues reflecting off the white limestone but also because of the wide range of marine life.
Boat trips sail from all over the island but the nearest harbour is at Agios Nikolaos, near Volimes. Many visitors drive to Agios Nikolaos then take a short boat trip as sailing from the south can take a long time.
Daily trippers can also take in the caves at Sklavou and the hot sulphur springs at Xigia. The small beach, also called Sulphur Beach, is a narrow strip of sand beneath a stark sheer cliff.
