River Tubing, Snorkeling and Diving at Las Estacas

Las Estacas Natural Reserve and Spa, in Tlaltizapán Municipality in the Mexican state of Morelos, is built around a spring-fed river that stays a near-constant 22-23°C throughout the year, making it a year-round destination for river tubing, snorkeling, and scuba diving. The day pass gives access to inner-tube floats down the gentle current, open swimming areas, and roped-off sections for stand-up paddling, while snorkel and scuba tours run separately through the deeper spring pools, where visibility frequently exceeds 10 meters thanks to the filtered spring water. Tubing and swimming require no prior experience or minimum age, though children under 1.25m qualify for a reduced day-pass rate and should be supervised in deeper sections; snorkel tours ask for basic comfort in water, and the scuba tours require either a certification card or completion of the park's introductory dive briefing for first-timers. Inner tubes, life jackets, and snorkel or dive gear are provided as part of the respective tour prices, while visitors are expected to bring their own swimwear, a towel, and a change of clothes. Las Estacas has operated as an eco-tourism reserve for decades and is one of the better-known spring-fed river parks in central Mexico, with on-site lifeguards stationed along the swimming and tubing routes and dive staff who run pre-dive equipment checks and safety briefings before entering the water; the park maintains an on-site first-aid post for minor incidents. Because the river's temperature and flow are governed by the spring rather than surface weather, the park operates year-round without a true off-season, though the rainy season (June to October) can occasionally raise the current slightly in the tubing sections. Visitors aiming for a quieter experience tend to favor weekdays and the dry season from November to April, when park attendance is lower and conditions for photography in the clear water are most reliable.
