Had a cruise stop at Tobago, Trinidad and Tobago a couple of weeks ago. We took an independent trip up to the Argyle Waterfall, a famous waterfall near Tobago with a 3-level drop of 54m into a series of pools surrounded by jungle.
It was a fabulous walk through the jungle up to the waterfall, then a climb up the different stages of the falls and a swim in the top two pools.
Definitely one of a Top Ten Tobago must do. It was $10 US entry without a guide and a minibus cost approximately $120 US return. between ten of us.
