Tropical Islands Rainforest... Deep in St Lucia's mountainous, tropical islands interior almost 1,800 feet above sea level, lies 19,000 acres of rainforest and the 29 miles of trails that run through it.
The rainforest is respected as a habitat for rare birds and plants, a world where lushness is overpowering, where elusive parrots squawk overhead, orchids scent the air, hummingbird buzz near brilliant heliconia and climbing palms encircle tall trees like lovers in a parting embrace. It has taken centuries for St Lucia's tropical island rainforest to become its current well-developed refuge. Nonetheless, two thousand years ago, Arawak tribes associated the dark woods with evil spirits and for centuries the forest remained untouched and the spirits the Amerindians feared evolved into island folklore.
