John “Caveman” Gray and company have been leading eco-friendly nature tours around stunning Phang Nga Bay since 2001. In other words, they know it like the back of their hands. After your sea kayak tour with them, so will you. Ranging from day trips to overnight journeys that include beach camping and bioluminescent plankton experiences, the excursions balance action and adventure with educational insight. They’re so well done that many copycats have sprung up over the years, but John Gray remains the best.
