We hired four single kayaks for four adults for a three-hour slot and booked in at the office in Crystal River, where some very pleasant staff issued us with snorkels and masks. We were given an iPad and all asked to watch two videos about safety and the rules about Manatees and other wildlife. We were directed to a venue with car parking a short distance away, where we set off from the launch area onto Crystal River itself. The water was calm and shallow. We paddled into Kings Bay and entered some of the small rivers that lead to various springs where you could swim in clear safe waters. A map was provided when we collected the kayaks along with buoyancy aids although we didn't see many others wearing them. The kayaks were in good condition as were the hired snorkels and masks. Three hours was enough and we all really enjoyed ourselves. We felt that it was a great value for money trip.
