More ways to explore the area's outdoor wonders
You step off the van onto a sun-warmed limestone road and the air changes—humid, green, threaded with the distant chirp of birds. In Homún, a scattering of trails and the Santa Bárbara Express line lead to sinkholes that gouge the karst plain, their water so clear it looks like glass pulled taut over a secret world.

Shower before you swim
Showers are available and required—no lotions or sunscreens in the water to protect cenote chemistry and wildlife.
Wear water shoes
Rough steps and slippery limestone make closed-toe water shoes a better choice than flip-flops for entry and exits.
Bring biodegradable sunscreen and repellent
Even ‘eco-friendly’ products vary—use clearly labeled biodegradable formulas and rinse off before entering the cenote.
Start early to avoid crowds
Meet at the Mérida meeting point and arrive early—cooler light and fewer visitors make for better photos and calmer water.
