    I have tried contacting AkuAdventures at least 6 times and never get a response. Are they still in business? I used them on the bioluminescent kayak tour in January 2010 and would like to use them again because of the glass-bottom kayaks they used.

    I thought you should know so you could update your site, if they are no longer in business.

    • Coqui says

      Not sure if they r still in business but I find ALOT of operators here ate not great at answering calls and even worse answering emails

    • says

      Eco Adventures still in business but only 2 companies work on sunday. They are slow answering the calls. In you need some help about it visit my web. Mora

  2. robin says

    Are any of the BioBay operators open on Sundays? I can’t seem to find any that are. We are only going to be in PR on a Sunday from 3pm-midnight, and this is the one activity our entire family wants to do. (if no one is open, could someone please explain to me the reason)….thanks.

    • Coqui says


      Most do not go out on a Sunday so that the bio bays get a break from the tours it’s a way to try to preserve it

      U could try Akuadventures as I have read that they do Sunday’s but I have no first hand experience with them

      Good luck

    • gayle says

      I just read on elyunque.com/biobay.html. (I had googled biobay and kayaking tours and came up with this) it is under fajardo tours). They state there that if you can only do the Sunday to contact them and arrangements may be available. 787 435 1665. This could be our issue too as our cruise comes back sunday am and we fly out mon.
