Glad you people liked it, as I said I have seen quite a lot (by means not all, of DR, and quite a lot of other beaches Tahiti, Australia, Brazil) and this is one of the most beautiful. This is his website:
Harleys Heaven.
He had some problems with his previous site, but I guess he fixed this one now. By the way he has INTERNET there as well. :-) (satellite)
As to what can you do there? Well it is not really for snorkeling, as there are waves. The excursion (driving your self) to the Montaņa redonda is worht the trouble. You can also get horses and go horse riding (cannot remember the prices, but Andy will know), or go for a boat trip to the Laguna Redonda (I brought my own inflatable kayak, so that was not a problem). But the best is to explore the beaches with 4x4, and getting coconuts and making coco loco :-). bring your own machete, rum and ice. Be warned, not all is paradise, there are mosquitoes and sand flies, in the afternoon. So take repellent. Not much hiking, as it is too hot anyway. I did not go there during summer, as I guess it would be too hot without air. But it was OK all the way to may.
Andy is real helpful, and if you can mention that David send you. He is also on skype his nick is "harleysheaven".
Oh I guess you can also arange excursion to see the whales, but that would be from Mitches I guess, ask Andy about it, he has some friends who do that.
