1) We are hoping to visit Mosquito Bay on Vieques to see the bioluminescence. There seems to be surprisingly little info from cruisers who have also done so. I am curious if most anchor off Esperanza and use a tour group or try to anchor in Sun Bay and dinghy around on their own? I suppose one could anchor just outside of mosquito bay entrance but it looks like a relatively unprotected place to spend the night.
We did Mosquito Bay in April. It was something of a disappointment. We got a ball off Esperanza for a couple of nights. (Call Glenn Kranig 340-227-4288 or Christina 787-930-0831). Glenn is also a good source of advice re restaurants, dinghy tie-up, etc.
We used one of the tour services. They meet you with a van near the El Blok Hotel, drive you to the launch site, and take you out on two person kayaks in a group. Our guides were excellent. There were two problems: we were locked into a single date, with about a half moon, and the hurricane effect. Even with a half moon, it was very bright. And the guides explained that the bay had not yet recovered from the effects of the hurricanes 7 months earlier. The guides tried their best, by providing parachute cloth for covering in an attempt to block the moonlight. We could see a faint green glow, but nothing close to the luminescence seen in on-line photos and videos. In short, a worthwhile experience for $50, but not what we hoped for.
