I took my kids to rio seco waterfall in matura/salybia couple of weeks ago with the guy who owns naturetrekkers. he is a boss. one of the best most professional guides in trini. He real cool also. He placed a rope from one end of the bathing pool to the other end so u could pull yourself across the waterfall. Needless to say a few weeks alter it was stolen.
I been to quite a few places on that list. RIO SECO IS THE BEST WATERFALL IN TRINIDAD. hands down!!
It has the best bathing pool(although very friggin deep its about 15feet ) and the trek is relatively easy and very scenic and beautiful I would recommend that hike and that guide to anyone any day.
Wish i could have posted pics but i cant cause my students in all of them. But trust me, walking through that mora forest real nice.
I have contact info for him if anyone wants to go on any hike or excursion with him whether trinidad or tobago he does both.
