Lago Tecocomulco

The Lago Tecocomulco is an ancient and scenic lake and wetland in the far east of Hidalgo, just south of Tulancingo. The aquatic ecosystem is home to carp, ducks, herons, frogs, rabbits, coyotes, squirrels, and plant species that include lily, begonia, water lily, and the surrounding nopales. The lake is perhaps most famous for being the last of the very ancient Anáhuac lake systems.

While the area is not formally a protected wetland, it has been a Ramsar site since 2003. That affords some protection to the wetlands that are among the most important in all of Mexico. People visit for the peaceful adventure, and the lake side caters to shore-side activities. Frequent family reunions and similar get-togethers take place here nearly year round. 

If you won't get into a canoe, there are also some hiking trails in and around the northwestern shore (especially).  

People come south from Tulancingo. It's about an hour drive. Tepeapulco is a little closer at just about half an hour to the west of the lake. Archaeological finds there are in the former San Francsico Monastery which is replete with early colonial-period murals and the nearby Xihuingo archaelogical zone is always worth a visit too. The main visitors area for the lake is along the northwestern shore where a small town called San Miguel Allende offers some services, as well as restaurants and eateries. These will continue at the northwest point of the lake, at the little town of Tecocomulco de Juárez.
