Grand Etang National Park
In the center of Grenada lies the Grand Etang National Park. You can drive directly to a lake and there are several trails through tropical jungle scenery. I hiked for about an hour to the Mount Qua Qua and I saw free-living monkeys.
In the capital St George is the Fort George on the mountain with a beautiful view of the harbor. The Grenada Museum was well laid out and I walked along the harbor.
