Water Mine Procedures and FAQs

This family water park captures the excitement of the Old West's Gold Rush with attractions tailored for all ages. The Water Mine Family Swimmin' Hole offers more than an acre of slides, flumes, sprays, showers, floatables, and an interactive water playground. Careen off covered wagons, float on wild animals and dash through showers tipped from water-filled ore carts. The activity pool is encircled by Rattlesnake River, a 725 foot lazy river you can enjoy a relaxing float as the current gently nudges you along.

The centerpiece is Pete's Peak, a craggy mountain dotted with boarded up mine shafts and tunnels. Several slides of various size and intensity jut from the mountain, giving a variety of thrills you'll return to again and again. Enjoy a slide down Big Pete and Little Pete, or experience the thrills of Prospectors Plummet with one of three 3-story waterslides!

The mountain and slides are named for Pete the Prospector. According to Lake Fairfax legend, he staked his claim there in 1849, searching for gold. Sadly for Pete, his years of digging found only water. But now, with The Water Mine, the Park Authority is turning Pete's worthless old strike into the golden fun of summer.

There's something here for everyone. Tenderfoot Pond, with its pint-sized slide and gentle bubblers, gives toddlers a perfect place for water play. Children will delight at the never-ending bubblers and spray fountains in Boomtown, a multi-level water playground, along with the interactive slides and additional interactive features in the tot spray pad area! The more adventurous can test their skills on Box Canyon Crossing, the log walk obstacle course. Teenagers can join a game of water volleyball or enjoy the thrill of Prospectors Plummet, and everyone will enjoy going with the flow in a tube on Rattlesnake River.
