I consider myself very lucky to live as close to Heritage Park as I do. It is a fantastic park with a lot to offer... In fact it is THE largest multi-use sports complex in the Las Vegas Valley!!
The Aquatic Center is one of the best in the city. You can read my review of the center here:

The Bark Park is a welcome addition to the area. It is Henderson's largest dog park. (Note to self, review the dang dog park!)
My favorite aspect of this park is the running path around the perimeter, and the trails that criss-cross the center area of the park. I love having a well-lit running path complete with mile markers so close to home. In fact, I love it so much I canceled my gym membership... Nothing at the gym compared to watching the bunnies scamper out of my way as I come running by.
With all this park has to offer, I do not understand how anyone can NOT be a fan.
