.......yes, but St. John’s is a tiny island. You can ride from one end to the other in less than 30 minutes. The extreme eastern end has a neat bar on a cove with lots of sailboats. We pulled in there after getting caught out in 25’ waves in Hurricane Maria in Sept 2011.
Also, you can ride a free bus from one end to the other. Hold on! The drivers are crazy. On the western end it’s got lots of nice shops and a small boat rental business right on the water. Restaurants are good to very good and during the daytime there are hundreds of people out so you will be safe. You will see though that very few are out very long after dark. After midnight is practically unheard of anymore for thinking tourists.
As you get off the ferry on St. Johns, walk straight ahead across the little shaded public plaza and at the back is a Texas Restaurant owned by a Texan. He’s cool and has good food and prices.
And, yes, St. John has the big park that I think Rockefeller or someone like him gave to the government. I never went in it. You need to say where the people are. Indeed, you need to “be aware of your surroundings at all times”.
Whatever you do, don’t go to Fredericksted on St. Croix even for a visit. Ok to go escorted by Locals but only in the daytime. Go to Christiansted in the center of the island. Lots and lots of shops and bars and generally safe in daylight hours. The old 300 year old Fort is interesting. I spent a lot of hours there.
I have a buddy who will take you out on his boat (with a group of about 8-10 others) and he is completely reliable!!! He will take you to Buck Island which is the largest underwater National Park in the US. That little day trip is really worth the effort. I think his normal charge for the day including some drinks is 75 bucks.
I also have a buddy on St. Maarten that would take you out as well. Probably for free. He’s cool.
Even St John is unsafe at night! I have an acquaintance who bought a condo there. I was under the impression that it was a paradise.
