We were just in Fredrickstad yesterday, Not easy to find a taxi unless you have 6-8 people. Finally others standing around us were asking the same. We ended up with 8 and the cost was $25 pp round trip to Christiansted. Our driver waited and we spent about an hour there.    Very disappointed in this St Croix port stop...we'll hopefully avoid this one in the future. Really nothing to do in either place....unless you're looking for a beach day....we weren't.
