We recently spent a few days on Vieques during a trip to Puerto Rico and it was very relaxing. We stayed at Bravo Beach Hotel which was gorgeous and worth every penny (see my review), and we went on snorkel and biobay tours with Blue Caribe (near Sun Bay beach in Esperanza). Our experience with Blue Caribe was great. I had never kayaked before, but we had to kayak to a smaller island in order to snorkel. It was pretty easy. Our tour guide did not speak English, but he was very nice and we enjoyed our first time snorkeling very much. The cost was about $60 for the 2 of us. Plus it felf like a private tour since no one else had signed up for that time slot. That evening, a different tour guide drove us to a marshy area for the Biobay tour. Beware of the mosquitos! I think they were waiting for us as our van pulled up. We were clobbered as soon as we exited the van. I've never gotten so many bites (these were very small ones though). The tour guide placed a light on himself so we'd know what direction to kayak in if we fell behind (which I did). There were 5 couples all together, 4 of which chose double kayaks. We opted for single ones since we had double kayaked earlier that day. As we rowed through the water, the guide stopped periodically and gave bits of information. He was very charismatic and once back in the van, told us stories of the famous people he had given tours to including Oprah, Mariah Carey, Alicia Keys, etc. After kayaking for about 20 min we finally stopped and the guide anchored the boats together. He showed us how to jump out and how to jump back in. There was no concern about being able to swim because we all had life jackets on. So as soon as you jump in, your body automatically bouces upward. It's a very quick dip. The water was lukewarm, not shocking at all. And then you get to experience the glow. Wow! It was pretty amazing, especially since there was a full moon and I'd read that a full moon prevents a brilliant glow. Well that was pretty brilliant to me!. Our entire bodies glowed and when I lifted my hands out of the water, I could see the tiny animals all over me, spilling downward back into the water. It was an exciting experience, but calming at the same time. There is nothing around the bay but marsh. So everything was pretty much pitch black aside from the glow and the moonlight. All is quiet. You feel like you're miles away from civilization. And that's when the jellyfish sting occured. Not to me, but my husband. We notified the guide who had warned us about the risk ahead of time, and he gave us vinegar (i think) to apply to the sting. It wasn't a big deal and I wouldn't let it stop me from visiting the Biobay again. I think my husband had forgotten about it by the next day. The guide also informed us that jellyfish season ends around May, so we must have caught one of the stragglers. Next time I'll consider wearing a wetsuit and maybe some of those rubber socks for this tour. You have to treck through mucky mud a bit to be able to push off in the kayak, and it's cold when you get back to shore (I guess rowing kept us warm). And that would help prevent the crazy barrage of hungry mosquitos. The guide drove us back to Blue Caribe and called a Público that could take us to a restaurant in Isabel II (since Blue Karibe is in Esperanza). The Públicos are large capacity vans that pick passengers up and take you pretty much anywhere for $3 during the day, $5 at night. Generally I was grateful for the públicos because 3 bucks beats a $75 car rental anyday, and you can catch a público anytime. That particular driver drove WAY too fast though. We got off at Richard's Cafe, a 10-15 min. walk from our hotel. The food was good and the waiter was very nice and accomodating. I wish I got his name, he really was a friendly, genuine young man. We also ate at Shaunna's the day before. You get a giant plateful of authentic PR food for $6!!! The chicken was not my favorite (my husband liked it), but the beans, rice, and tostones was enough to keep me coming back. It's a small family run restaurant, only open a few hours each day, and the plate I described is pretty much the entire menu. But if you're traveling on a budget and want authentic food, Shaunna's in Isabel II is the place to go. One more note about traveling to Vieques. Yes the ferry is only $2, but we waited a LONG time in a LONG line to get tickets. Then the ferry ride was 90 min. long. I was SO ready to get off that boat!!! We chose to fly back so we caught a püblico for a ride to the Vieques airport ($10 total). The flight fair was about $25 each and they'll ask your weight so be ready for that one. The plane was for 8 passengers. The ride was 10 min. long and we got spectacular pictures of the reefs off the coast. Overall, I loved staying on Vieques. It was the ultimate relaxing experience. We roamed empty beaches, shopped a little, ate well, kayaked, snorkeled, and swam. What more could you ask for???? I'll definitely go back again....and again....and again.
