I booked the kayak tour, but choose to do the walk into the ocean tour instead. December is not the greatest time to do Bioluminescene Tour, it's not summer here and the water is cold and not enough plankton to create bright blue colors.The best time to come to Holbox and do the tour is in the summer July,August, and September. I was able to see minimal lights. It was cloudy, I took a few pictures of the constellations. I was picked up at my hotel and dropped back off. The whole trip was about one hour. The service and tour guide was great!!
