there are lots of places
For example, everyone will tell you about the falls, the river rafting, the beautiful scenery. There is horseback riding, and golf, too.
You might enjoy Santiago with some history and a very typical, non- touristy style...good food, nice people, the ruins of the Old Santiago are located just a few minutes from the center of town...
San Jos? de las Matas is like Jarabacoa...
Up in San Juan de la Maguana there are the Indian Rock Circles, used before Columbus for religious(?) ceremonies.
Lots to see.
