Dominica

The tiny, steep village of Wotten Waven has a stunning natural setting and is well known for its natural hot sulfur springs that are said to have medicinal qualities and help cure everything from rheumatism to foot fungus. After a hard day on the trail, taking off those boots and soothing sore muscles in the naturally muddy water is a delight. Enterprising villagers have created several spas where relaxation-seekers can wallow in open-air pools surrounded by lovely gardens. All stay open after sunset, allowing you to chill under the stars, Kubuli in hand while being serenaded by tree frogs.

The water looks 'dirty' but is actually naturally orange. Clean water is piped into the pools so that there's circulation, though you'll want to rinse your swimwear after bathing.

Just beyond the visitor center here you'll find a viewing platform with full-on views of the two side-by-side falls: the 125ft 'Father' fall and 75ft 'Mother' fall. Following the narrow rocky trail beyond the platform means negotiating slippery boulders, so wear sturdy shoes and watch your step. You can cool off in the swimming hole below Mother fall. If you want to hike to the hot springs below Father fall, a guide is recommended.

One of Dominica’s most popular underwater playgrounds has you snorkeling amid volcanic bubbles emerging from vents beneath the sea floor and rising up as drops of liquid crystal, making it feel like you’re swimming in a giant glass of champagne. Best of all, you can snorkel right off the (rocky) beach. Technicolor fish and coral abound.
