Akumal, land of turtles, is located 40 km away from Playa Del Carmen and has a lot to offer. Here you can swim with turtles, and enjoy the amazing beach. It’s easy to get there with the local colectivos that take you from Playa del Carmen to Tulum. This will only cost you around 35 pesos. As it is a pretty touristic place I recommend you to go early in the morning so that can enjoy the place to the fullest.
Personally, I took my GoPro with me with the intention of taking pictures of the turtles, but as you can see it hasn’t been very successfully.
