Trinidad cave tours

In Trinidad & Tobago, visitors can take a 3-hour guided tour of the Gasparee Caves on Gaspar Grande island, a 15-minute boat ride from Chaguaramas. The limestone cave system features stalactites and stalagmites and, in the largest cave, a tidal pool called the Blue Grotto, 100 feet underground and illuminated by natural light.

The cost is TTD120 (near $18), adult, or TTD90, child. Call +1 866 225 4232, ext. 191, or email Melissa Bernard-Patel (mppatel@chaguaramas.com).
