Opening in Pleasanton on November 11, 2005, located only a short drive from San Jose or San Francisco, Callippe Preserve is a unique and memorable course. Designed by Brian Costello, of JMP Golf Design Group, "Callippe Preserve was designed to cater to the wide spectrum of players anticipated to frequent the facility", says Costello.

There are five sets of tees on this par 72, with the black tees playing at 6,748. The blue tees measure at 6,409, then the white tees at 6,024 yards, the gold tees at 5,560, and the red at 4,788 yards.

Varieties of terrain are spread throughout the course as the front nine is routed through the valley and the back nine sits on a higher elevation with the Happy Valley Creek winding throughout. Superior views of Mount Diablo fill the sky line to the north and incredible sanctuaries dedicated to the Callippe Butterfly are displayed on holes 11 thru 14.

At Callippe Preserve we strive to make each hole a signature hole. "We have strived to create a flowing sequence of unique and memorable holes that will add up to an unforgettable golfing experience. However, our par 5 number 18 seems to stand out as one of the most strategic and dramatic closing holes in the Bay Area. Happy Valley Creek meanders across the hole no less than three times to set up the hole. Nestled in the valley floor with large oak trees framing the vista, players will need to navigate the hole with three accurate shots to avoid the creek and the strategically placed bunkers to reach the large rolling green," said Costello.
