We took hired a taxi van for the day in Dominica ($30 each). It was a GREAT day! This was a fascinating tour of a beautiful rainforest island. It is another highlight of the trip. The lush vegetation, flowers, and fruit trees made this a spectacular trip. The driver was a great tour guide, and took us to a sulfur pond, Trafalgar Falls, Emerald Pool, and a black sand beach. (Note: some hiking up steep slopes and rocky loose terrain required) We made many stops at interesting places. Dominica is unspoiled, and not really set up for mass tourism. I love Dominica, and it was MY favorite port. People were the friendliest I have seen. Do not leave this island without trying the fresh fruit grown there. I never knew a banana could taste so different. There is a fruit stand where you can try all kinds of fresh fruits for free. (tips only) The man who runs it is entertaining and funny. Go see him.
