Little sparks in the water - It is a fantastic experience. Let the guide surprise you with all the great information. One of the most incredible experiences I ever had. It was an incredibly peaceful spot we went to I could have stayed in the water for hours just watching the show in the darkness.

Swimming in Pandora - Really wonderful. Highly recommended. As my son says, it’s like he was in Avatar and swimming in Pandora. Make sure there is very little to no mood light to be able to see the bioluminescence. It’s not glowing blue like it surges in the pictures, but it’s very beautiful. More like fireflies in the water. Or stars in the water. Definitely get in the water to have a better view. Our guide was very helpful. They even helped dropped us back off at our hotel. Would definitely do another tour. Would love to do the bioluminescence tour again. Very excellent

Bioluminescence - Very nice experience, I was impressed to see the bioluminescence. It is important to note that you can appreciate well with your eyes, however, the camera does not do you justice.

Sunset Boat Tour with Bioluminescent Night Swimming - This tour was one of the highlights of our trip to Costa Rica. We were on the water for the sunset, we were able to see various birds on the islands, historical mini tour of the San Lucas Prison, and our guide Olger and captain were excellent. The bioluminescent piece was amazing and this seems to be a great time of year for it. Fees were appropriate for amount of time on the water. We were out about 2.5 hours.

STOP - you will not be disappointed - join this amamazing trip :) :) :) - We went on a work conference to Costa Rica and joined the tour after recommendations from locals in Costa Rica. The trip was amazing in so many ways - great company with other tourists from Mexico, Venezuela, Chile, Guatemala, Peru, and the United States. We couldn't have had a better guide - it's a magical place to visit in this season as all of the islands are completely green and lush and low tourist season. The bioilluminous bay was nothing short of magical - as the tour guide said, it's time to return to our youth and play like kids! Highly recommend this company, staff, and even food afterward - great potions that will leave you full and happy!

An unforgettable experience - The best experience, in addition to the tour show you and make a brief explanation of the Islands, their biodiversity, their history. Coco's Tours gave us a wonderful experience and we felt like children playing with bioluminescence, as well as having the opportunity to enjoy a spectacular sunset.
