Happy Valley is situated in a narrow valley of the same name on the northwestern fringe of the Great Smoky Mountains.
 Chilhowee Mountain— an elongate ridge stretching for roughly 35 miles (56 km) between the Little Tennessee River and the Little Pigeon River watersheds— spans Happy Valley to the north.
 The valley is walled off to the south by several low ridges— namely Pine Mountain to the southwest and Hatcher Mountain to the southeast— which run roughly parallel to Chilhowee Mountain.
 Cades Cove is located opposite Hatcher and Pine Mountain to the south.
 Happy Valley Ridge provides the valley's eastern barrier, splitting it off from Lake in the Sky and the Top of The World community.
 Gregory Bald and the main crest of the western Smokies rises beyond Pine Mountain approximately 3 miles (4.8 km) to the southwest.

Abrams Creek, which rises in Cades Cove, flows northwestward through the gap between Pine Mountain and Hatcher Mountain.
 Before it reaches Happy Valley, the creek turns southwestward and flows for several more miles before emptying into the Chilhowee Lake impoundment of the Little Tennessee River.
Happy Valley's two major streams— Mill Creek and Bell Branch— are tributaries of Abrams Creek.

Happy Valley Road, which connects U.S. Route 129 with the Look Rock section of Foothills Parkway, is the only major road access for Happy Valley.
The road is accessible immediately southeast of the parkway's terminus along US-129.
