On 4x4s, explore the rough countryside of Mirambello and visit the historic island of Spinalonga - the "island of tears" - by paddling two-seated sea-kayaks.

Begin with a 4x4 jeep tour to explore the unique Mirabellos area. Leave the highway behind and drive to Milatos village, to visit its historic cave. Then continue until you reach Skinias village, for a stop for coffee and refreshments.
Cross the Aforesmenos cape, driving either on coastal areas or on dirt roads that offer breathtaking views of the bays of Elounda and Spinalonga Island. You will end up at Plaka village, where your sea adventure starts.

At the water sports base you will have some free time to rest and swim, and enjoy your BBQ picnic lunch (vegetarians lunches can also be provided). You will also get some instruction on how to paddle the two-seated sea-kayaks that you will soon take out. Board the kayaks, beginning with a gentle slow row to the island of Spinalonga. After a swim break at Spinalonga's beach, explore the historic island that was a massive fortress for the Venetians and was later used as a leper colony. When you are done, paddle back to the base, where you will board your transfer back to Heraklion.
