A cenote (SEE NO TAY) is a natural pit or sinkhole that results from the collapse of limestone bedrock that exposes groundwater underneath.
The BBC produced a 5 part documentary series about the Mayan civilization and cenotes. Take a look at it here.
There are many cenotes throughout the Yucatan peninsula. The cenotes closest to Puerto Morelos are on the Ruta de Los Cenotes.
For a fun day, pack up a picnic and head out to one of the cenotes near Puerto Morelos!
The Ruta de Los Cenotes (Cenote Route) is a road found just south of Puerto Morelos that leads to another small town, Leona Vicario. Look for the arches above the road to the west of highway 307. There are several cenotes along here, also known as sinkholes. These cenotes are a natural marvel feeding from underground streams and rivers that are all under the Yucatan peninsula.
