This excursion is located on the island of Vieques, Puerto Rico. In order to participate in our tour, an overnight stay on Vieques is required. Vieques is a separate island off of the main island of Puerto Rico. You will need to take a plane or ferry from the main island of Puerto Rico to reach Vieques, and you will need to arrange separate ground transport because you will not be able to bring a hire car on the ferry with you. Because we only offer tours at night so that our clients can experience the glow of the bay, even if you take our earliest tour, you will not be back to our meeting point with enough time to get on a ferry or a plane back to the main island on the same day. Our guides will meet you in Esperanza directly across from Rainbow Realty (278 Calle Flamboyan). Return from the meeting point, the excursion is 2 hours, time on the bay about 1.5 hours, weather permitting. We provide transport from the meeting point to the Bio Bay entrance and back.
