A trek through the Grenadian rainforest is an adventurer's dream come true. So get ready for a hike that takes you through some of the island's most breathtaking landscapes to the Seven Sisters waterfalls (be sure to wear a bathing suit under your clothes if you decide to take a dip in its pool). From the pier, you'll journey through St. George's before heading inland and climb up the mountains to the Grand Etang Forest Reserve, a green paradise set 1,700 feet above sea level. Once at the trailhead your guide will lead you along a narrow, and at times, challenging trail. At the falls you'll notice that it's actually two, each with big rock pools suitable for swimming. You'll have ample time to take photos, cool off with a beverage, relax or swim before hiking back to meet your transportation and returning to the ship.
