I have never heard of the existence of a DETAILED street map of St. Thomas, either online or hard copy.

Here's one I found online: http://www.usvi-on-line.com/st/stmap.shtml

Thanks, that's the best I've seen yet.

Larry,

The link islandjoan provided is to an online copy of the map that is provided to tourists for free at the airport. You asked about a "detailed" map with street names and while this map shows some streets it does not include any street names. In my experience island addresses are vague generalities, just the estate where something is located, and specific places, like homes and businesses, are found using landmarks.
