Thanks for the valuable information about this park. It really seems to have the 50 shades of green. It looks like a vast area, Did you explore all of this in one day or did you have overnight sleep in a tent or a hut or something (even though you said no man's land).
Greetings from Cape Town :)
mostly i took 2 or 3 days for visit the area, cause the distances are very fare from the capital Santo Domingo (5-7 hours drive). I spent often times in smaller hotels.
