If you have an existing booking or are thinking of booking the new SLS Playa Mujeres better think about cancelling ASAP or start looking at other resorts. Looks like they have run into legal trouble with the Mexican government and have to sort that out before any guests can enter the property.
Cenotes are infinitely beautiful, interesting places filled with Mexican history. There are between 6,000-7,000 of them in the Yucatan Peninsula alone (most likely an underreported number) with only around 150 that are currently open to visitors. In case you don’t know, cenotes are basically limestone sinkholes that form when limestone bedrock partially or totally collapses and exposes fresh groundwater. Cenotes are practically everywhere in the Riviera Maya, and more are being accidentally discovered all the time.
