There is room for 3 boats to anchor just to the left of the 2 green markers as you come in the channel to customs. I did it twice this week. Then dinghy to the natl park dock and walk over. We tried the roam app but had a glitch and had to go in person. The folks there were very nice and no charge.

Coming back to the bvi at west end we got hit with the harbor fee of $1 per foot. Also charged $30 fo some type immigration fees that I really didn't understand and haven't paid before. Just depends on the day and the person.
