Visit the Fajardo BioBay in an Electric Boat

6/21- BioIsland is making reservations and a wait list for tours….If you want to go on an electric boat, check them out!

Bio Island Electric Biobay Boat in Fajardo

Puerto Rico is blessed with a natural phenomenon that is found in only a few other places on earth — it has 3 year-round bioluminescent bays (or BioBays). There is La Parguera in Lajas in the south-west of Puerto Rico, Mosquito Bay on Vieques and, the most visited one, Laguna Grande in Fajardo in the north-east of Puerto Rico.

I am so happy to say that there is now an eco-friendly way to visit Laguna Grande without having to kayak or walk. Bio Island is the company that offers an electric motor boat tour that is both safe for the environment and fun.

Bio Island’s Boat

The boat they use has a duel motor. The motor it has been approved by the DRNA. Bio Island tour is really eco-friendly. They use a really quiet Minn Kota electric motor that is mounted on the Honda low emissions gas motor, so it can be interchanged by a flick of a switch. They use the gas motor until they get into the channel and then switch over to electric. The boat is a small Carolina Skiff, so it has a very low profile — not much deeper than the kayak bottoms.

There was always a question about the other electric boat company following the DRNA rules and whether they used the electric motor, so when I went on this tour with this new company, I did it anonymously. I really watched and asked lots of questions and I am happy to say they followed all the DNRA rules and have a few ecologically friendly ones of their own too (like no eating/drinking in the boat- so no trash ends up in the water). And they are even applying to get "Blue Flag" status for their boat/trip. Yea!

Our Trip into Laguna Grande

The tour was really nice (and relaxing!). I went out with some older guests, who were staying in our rental, who were unable to kayak or walk very far, and the Vieques trip was out of their budget. This trip was perfect for them!

Bio Island Electric Biobay Boat in Fajardo

We left from the Las Croabas boat ramp, where they helped us into the boat. Since we were all together, we could all talk, interact and learn the whole time. Throughout the tour Captains Ron and Charlie told us about the boat/engine, the other boats docked in the Las Croabas area, the Biobay, the fish, the dinoflagellates, and they even had some jokes to tell — lots of good information. Charlie and Ron were such gentlemen, too — when it started to rain, they gave their jackets to the older ladies in our boat. I think they offer great customer service.

The tour lasts approximately 1½ hours. Since we got through the channel and into the lagoon quickly, we were able to spend about 45 minutes in the biobay itself — swirling our hands in the water to see the glow, smacking the boat to scare the fish and watching their glowing paths, talking and enjoying the stars and the evening. On the return trip, we stopped to wait while the many kayaks made their way through the channel, so we didn’t collide with them.

The bay is connected to the ocean, so as the tides change, it does get to be low tide and the channel gets shallow. The motor is the deepest part on their boat, so they lift it to avoid hitting the bottom and stirring up the silt. On the way back, after we got out of the channel and into the marina, there is a very shallow area. So Captains Ron and Charlie had to get out of the boat and walk the boat across the sandbar. We just sat there and cheered them on! Both before and after the trip, they had chips and water/soda for us to enjoy.

I really liked this tour. I think it is a great option for people who are unable to do one of the kayaking tours, such as people with small kids, elderly, handicapped, etc. or people who just don’t want to kayak. It is easy and eco-friendly. The only negative is that space is limited — they can carry a maximum of 6 people per tour.


The cost is $52 for adults, less for kids. Reserve your trip online.

If you're happy, let them know it — Don't forget to tip your your bartender, tour guide or trip operator if you enjoyed yourself. Gratuities are appreciated and typically aren't included in the price they charge you.

They have 2 boats available for tours, so group 1 and Group 2 at each time. They do 2-3 trips per night, depending on the season and demand. Trips are at 6:00pm, 7:15pm and 8:30pm (times could be a little later in summer) . As of Jan 2019- The operate Monday through Friday, but will start Saturday tours when demand picks up. They take Sunday night off.

Minimum age for kids is 2 years old. It really depends on the size of the child and if an infant life vest fits securely.

Allow about 1½ hours for the trip, plus a little time before and after.

You can visit their web site for more information or make an on-line reservation! Click on the date (even if green) to see available openings.

As with any trip into any of the biobays, be sure to check our biobay/moon calendar to make sure the moon will be favorable for viewing the biobay on the night you want to go.

I heard last week that Fajardo is glowing very brightly. To get to the Vieques Biobay, you either have to stay the night or go on a boat trip over/back, which costs about $150 pp. Depending on the kids, you can decide if it is worth it. Or consider a walking tour at Las Cabezas to see the bay, they get to splash sticks in the water.

Hi .. we’re thinking to take the boat tour to bio bay.. Travelling with kids .. Planning to go this month .. Do you recommend this Fajardo bio bay or the Moaquito bay ?

Comment by Manjula S on 11 Feb 2019

There were only 2 electric boat companies, Baby Bay and Bio Island. You could try a walking tour at Las Cabezas

Comment by Gwenn on 31 Dec 2018

I just received a text from Bio Bay telling me that they no longer do the electric boat tours. Any other suggestions? My parents are in their 70s so I cannot do kayak tours because of this. Any other companies that do boat tours?

Comment by scott c schuster on 26 Dec 2018

No, I don't think either company has restarted from Maria.

Comment by Gwenn on 05 Dec 2018

Are there any electric/motor boat rides to Biolumuniscent Bay from Fajardo. I have been trying to call BioIsland, but the number goes directly to voicemail

Comment by GR on 04 Dec 2018

None of the biobay boat operators have transportation, only the kayak tours. You can try calling Hertz at the Sheraton Old San Juan (100 Brumbaugh Street). You would have to talk with them and maybe get an after hours drop off so you don't have to pay for the parking overnight.

Comment by Gwenn on 21 Oct 2016

We are staying in Old San Juan and would like to take a boat ride in bio bay. We are told renting a car from the airport. Our hotel has no parking and the parking is 5-15$ dollars per day. I am wondering if there is any alternatives...... Can anyone help us:)

Comment by Becky on 20 Oct 2016

For the Fajardo biobay, there are only 2 electric boats- Baby Bay cruisers and Bio Island. For Vieques bio bay, Island Adventures, and I don;t think any of the boats in Parguera are electric.

Comment by Gwenn on 04 Jan 2016

What are all of the companies that offer an electric boat experience? Looks like there are two here, but one is not mentioned by name. Are there others in PR as well? Thanks!

Comment by Margot on 04 Jan 2016

For Fajardo, you can try going on the night walking tour at Las Cabezas nature center. In Lajas, most of the tours of that bay are by motor boat (not electric). But the bay is not as good/bright. Or you can spend the night on Vieques and do the biobay their with Island Adventures.

Comment by Gwenn on 17 Apr 2015

Hi Gwenn, Looks like both companies are booked up at the moment - Bio Island will take waiting list and Baby bay will not. are there any other options ? How about biobay tour in lajas area ?

Comment by Sujit on 15 Apr 2015

Just keep trying to call. I think you can reserve online with the BioIsland, but no other option for Babybay. Try calling in the morning (about 9am).

Comment by Gwenn on 15 Apr 2015

Hello All, We are trying to reach out to both companies mentioned above but could not get any one answer calls ! Is there anyway to get hold of them. I sent emails too didn't work. -Sujit

Comment by Sujit on 14 Apr 2015

He is operating, just very difficult to get in touch! Keep trying, and try going to his webpage and send a message that way. But calling is best.

Comment by Gwenn on 18 Mar 2015

There's a concern that Captain Suarez's boat company is no longer operational. I reached them about a week and a half ago, and haven't been able to reach them since via phone or email. I've left multiple messages and called a few times a day. Someone posted on their facebook page having had a similar situation this month.

Comment by Keisha on 17 Mar 2015

We took the tour of the lagoon with the Bio Island crew this evening and had a great experience. Mario was very informative and having a biology background myself, I will say, that the information you are receiving is correct as well as entertaining. Job well done from Papi at the check in to Mario and the Captain on the boat. Thanks again and we'll see you again.

Comment by Frank Pagan on 19 Nov 2014

None of the electric boat tours of Fajardo biobay provide transportation. Your best bet would be to rent a car. But if you want to do a biobay in an electric boat and have transportation, contact East Island Excursions They do a great tour of the Vieques biobay. Just as an FYI, Oct 30th will not be the greatest night for viewing, but you will see something.

Comment by Gwenn on 21 Oct 2014

coming in on cruise ship 10/30 will dock at one ,will be in port over night , would like to book the bio tour, we will need transportion from old San Juan.

Comment by barbara geddis on 21 Oct 2014

I had the same poor experience as the reviewer above, though with the other boat company. We arrived 35 minutes early to take the first tour (6:45pm), though it didn't leave until 7pm. In the bay, we had maybe a total of 5 minutes or less to enjoy the bio bay glow, once it got dark enough, before the captain took us back into the mangroves. We left before it was even dark enough to see the effect very well. The whole trip was only 1 hour. We certainly felt cheated and were very disappointed! Buyer beware: do not go on the first tour of the night.

Comment by syrunsong on 19 Jun 2013

After seeing the posting here, my family & I decided to go with Bio Island Tours when we visited Puerto Rico in the beginning June 2011. Although I have been to Guanica and taken the ferry boat ride to the Bio Bay there, this trip blew the other out of the water! We weren't feeling the kayaking tours but it seemed the other people were having a great time. Our guides at Bio Island were very knowledgeable and they explained everything about our trip before and after we got on the water. It seemed like they coordinate their trips to the lagoon when the kayaks are back at the docks which made a trip a little nicer since we were on the lagoon by ourselves for a little while. Luckily, on our trip, we even saw a Puerto Rican Boa Snake in the trees on our way back in. The staff was friendly and our boat ride was one of the highlights of our trip to PR.

Comment by Brian on 14 Jul 2011

We appreciate your comments but also we reafirm that always, in all of the Bio Bay trips, we care for the safety of our passengers. One of our strengths is the VIP treat is given to all of our guests. Because you're using a nickname, I don't know who are you - so I can't answer directly what happened specifically in your trip (if you get late to the departure area, according to the schedule of trips, the time in the lagoon could be shortened in respect to the passengers in the other trips ... sorry if this was your case). Our experience, and the comments made by the 99% of our guests, has been excellent ones. Captain Charlie

Comment by Captain Charlie on 13 Jul 2010

Thanks for the very good information, really appreciate the hard work. But a word of caution about Bio Island. We first booked for a 930 pm slot, but a thunder storm was developing aroung 830 pm. I repeatedly asked Captain Charlie if it would be safe, he kept saying yes, it would be safe, "we would cancel the tour if we felt it would be unsafe". Eventually, the lightning wa so bright and thunder got so loud, we cancelled the tour ourselves. We felt they never cared for our safety. On second try, we did the Bio bay ride last week with our 2 girls and a couple of friends (a total of 6) at 630 pm as a later slot was not available. I asked "Captain Charlie" several times if going at 630 pm is too early (too much light). He assured me that we could observe the photo luminiscnence as early as 700 PM. Turned out we could only see anything at 740 pm and his brother "Captain Jeff" said that they had to go back to base for the next tour, so we got a scant 3 minutes in the lagoon.. We felt cheated. When we arrived to go on the tour, they never once told us of the dengue epidemic in PR. When we got bitten by musquitoes in the lagoon, they told us "sorry our dad screwed up not telling you to use OFF"... Now we are wondering if one of us is going to develop any sort of dengue syptoms... They did have a can of OFF at the sign up desk, but we were never warned / guided..
