Xcacel is a 25 pesos bus ride from Tulum. Take the combi towards Playa del Carmen. The entrance is 20 pesos.
Xcacel is a beautiful beach with palm trees rather than hotels.
The current was strong, but I did manage to swim all the way to the coral reef. The corals are not too interesting, but there are lots of colorful fish.
The cenote is beautiful, and very different from the others I have seen. It is small, but the water is crystal clear.
It is like it has a forest inside. On the bottom of cenote there are green plants and fallen leaves. Trees from the world above, stretches their branches down into the water. I saw a big crab that hid between the branches cloce to the surface. Many small fish played around in the water.
