Dunns river is great if you are physically able to "climb" the falls it is a must.

The most treacherous part of going there are the vendors in the gift area. they are very shrewd and charming. you should be able to get a t shirt for 10 us. however watch for the wood carvers and thier free gift "for the lady". they also use a trick..."follow him he will get you a bag" that leads you to the next shop.
