The Channel of Trikeri separates Evia from Skiathos and the Mainland. In the middle the Lefteris Reef, a shallow and treacherous structure that has caused shipwrecks for centuries; in fact, some of the ships that have wrecked here include some of the Persian fleet Xerxes brought to conquer Greece in 480 BCE, as well as the Greek Submarine Lambros Katsonis, which was lost during the second World War. While the seas are normally calm in the channel, the winds can be strong. With clear blue water, and plentiful marine life, this is a lovely place to enjoy some wonderful diving.
Electra's Cave I / II
At Electra's Cave I, you may be fortunate enough to meet the resident Mediterranean Monk Seal, who has been nicknamed Helectra. Not only can you explore a fantastic cave located at a depth of 12 meters, but you can enjoy a swimthrough that features a giant overhead dome. In addition, a volcanic wall drops all the way to a depth of 40 meters, offering plenty of nooks and crannies where crustaceans and invertebrates are abundant. At Electra's Cave II, you'll begin at the same cave, but you'll head to the southeast, toward two massive monolithic rock formations located at 40-45 meters. Throughout the area, you'll encounter a multitude of fish and other marine life. Due to depth, this pair of dive sites is reserved for experts.
Lighthouse
Located right off the site of the Trikeri Lighthouse, which was built in 1864, the Lighthouse dive site features ancient amphorae so old that they have become one with the rocks scattered across the white sandy bottom. Watch for all the crustaceans and invertebrates that hide inside the amphorae and under the rocks.
Kali Tichi Wreck
The Kali Tichi was built in Holland in 1917. 114 feet long, the motorboat traveled all over until finally sinking in Agia Kriaki's harbor on July 25th of 1975, while carrying a load of steel. Featuring maximum depth at 17 meters, the wreck is a favorite with all divers, particularly since it has huge open cargo bays and is in excellent condition.
Agia Vaso
A lovely site that is easily accessible from shore, Agia Vaso features a wall that first slopes to a depth of 23 meters, where a ledge leads the way to a steeper drop to a depth of 35 meters. At the base of the wall, swim throughs and large holes beckon, along with some large rock formations that shelter a wealth of marine life. The remnants of an ancient shipwreck can be found here; the ship's timbers are long gone but the amphorae remain, having become one with the rocks and sand over hundreds of years.
At Agia Vaso Deep, which begins at a depth of 30 meters, you'll find a fantastic gorgonian forest. As you make your way back up to the shallows, you'll be amazed at the abundance of colorful nudibranchs that catch your eye. This pair of dive sites is a favorite with photographers.
Argyronissos
Translating to "Silver Island" in English, Argyronissos is a small uninhabited island surrounded by magnificent reefs where corals and sea fans create an astonishingly colorful backdrop for an abundance of marine life, and where the wreck of a German ship dating back to WWII adds even more interest.
Life is laid back in the Trikeri area, with peaceful beaches, small restaurants and cafes, and friendly locals. The dive shops are well equipped and the dive guides are knowledgeable, making this the perfect destination for a fantastic getaway.
