Isaac Bay is a lovely, secluded beach like many on St. Croix but the hike down through the tall (sometimes over your head!) guinea grass on a small trail with thorny bushes right beside and over the trail was a bit much for us. We left our rental car at the trailhead with windows down and doors unlocked as suggested. We took plenty of water but for the condition of the trail, we should have worn long pants. It was very hot and humid, though, so we hoped we could make it in shorts. It was indeed a rough hike because of the overgrown trail. We didn't visit this beach again even though we were staying nearby.
