In reply to Leo Woodfelder:
Your assessment is pretty accurate- not much exposed rock- I saw nothing climbable inland on Trini and no rock on Tobago. The islands West of Port-of-Spain will be your best bet and offer some some DWS potential. I found some really fun overhanging limestone walls with tufas and pockets over good landings on these islands, only accessible / climbable off of a boat though. I spent a few hours exploring and climbing and I think you could get a couple of days worth of climbing there. Have fun on T and T, it is a brilliant place.
