27 Charcos
I have to agree, the waterfalls are amazing!! The guides are excellant help and really work hard. If you also have a great guide like we did, they appreciate a tip.
The website for the waterfalls is
Sending you to the 27 Charcos!!!. Take a pair of comfortable shoes (IE running shoes) with socks. If you do not have suitable shoes, they rent shoes for 40 pesos a pair but they don't have socks. Also, they do not have lockers, so whatever you take, expect to carry with you through the waterfalls. Although we personally didn't take our camera, there are some awesome shots and we've been told the guides are awesome at carrying the cameras for you (if you feel comfortable to trust them not to get it in the water).
Oh yea- and from Sosua, it's approximately 1 hour if you drive straight without stopping.
Have fun, you're going to love it!
