We booked a great excursion on St Kitts, independent of the cruise ship. Greg's Safaris - where we were driven with 6 others to the rain forest where we were able to do a 2 hour hike. Greg was extremely knowledgable about the plants and wildlife. He personally maintains the trail, and is the only one who does such a tour. He cares deeply about the island and protecting the rain forest. At the end he provided fresh fruit, sugar cane, and other island specialties for us to enjoy. Well worth the money ($60pp).
