Heart Reef – Queensland, Australia

Located in the Great Barrier Reef of the Whitsundays, Heart Reef is 17 metres in diameter and one of nature’s best mysteries. The coral formed into the shape of a heart by itself over time and was discovered in 1975 by a pilot. Unfortunately, swimming, snorkelling and diving is prohibited on the island. The only way to see this lovely view is by plane or helicopter.

Galesnjak Island – Croatia

Also referred to as “Lover’s Island” and “the Island of Love,” Galesnjak Island’s shape was first discovered in the 19th century by one of Napoleon’s cartographers.

Since the heart-shaped island is privately owned and uninhabited, there are no amenities or man-made structures. The island only consists of wild plants and trees making for a true getaway for those who truly want to feel like part of nature.

Lake Ouler – Wicklow, Ireland

Lake Ouler is located in Wicklow Mountains National Park and it’s definitely a sight to see. That is, as long as you can hike the challenging 33rd highest mountain in Ireland. The lake’s creation dates back to the Ice Age, when it was formed by glaciers and now sits on the side of the Tonelagee Mountain. Tonelagee stands at an altitude of 2,680 feet.
