I can't speak to the villa or it's path as I don't know which villa it is. Trunk bay is still very beautiful and one of my favorites. The beach is probably better than before with more sand and a much more gradual entry to the water.

The road was lost either in Irma or the August Monday flood in 2017 and has not been restored. After you make the last left turn to head down to the beach parking lot, the road is washed out about 30 yards down. You can walk from there to the old parking area and still hike thru to the beach but it's a much longer walk. It almost requires shoes. I have done it recently in flip flops but I don't recommend it. It's a bit treacherous and requires good balance. Don't plan to carry much other than a small cooler or back pack.
