( The Dominican Republic and Dominica are two different islands entirely )
Slim, Dominica is a very beautiful island. Lush, green and unspoiled. It's not overly developed as are so many of the islands. If you like nature then you will love Dominica.
There is a large population of Caribe Indians who make beautiful baskets, carvings, etc. You can take a tour back into the interior through the mountains and through the Caribe reservation. Get out and see some of the island and it's people.
Here is the official website for Dominica.
