The Preserve at Sharp Mountain (also called The Sharp Mountain Preserve) is a nature-based community located near Jasper, Georgia in Pickens County.
 It is one of three mountain communities in Pickens County, and the only one dedicated to maintaining its natural amenities.
 There are 12 mi of paved roads running through the community, but the population density is intentionally low (approximately 300 lots over 1600 acre ranging in size from a minimum of 3 acre to a maximum of 37 acres.)
 The Preserve at Sharp Mountain was named the "Best Community for Outdoor Lovers" by Pinnacle Living magazine, Unlike many planned communities, the Preserve at Sharp Mountain does not have swimming pools and tennis courts with club houses or golf courses.
 Instead, the Preserve at Sharp Mountain offers many acres of green space, hiking and nature trails, a nature pavilion, waterfalls, a bird sanctuary, a butterfly garden and various nature parks.
 The community is gated to restrict use of its 12 mi of privately owned roads to those living in the community.
 The Preserve at Sharp Mountain was developed by Four Seasons originally, which later became Naterra Land.
 Naterra's stated goal in all of its projects is "to better connect people with nature."
 Naterra Land sold out all of its inventory in the Preserve, and control of the community is now governed by a Property Owners' Association (POA).
 In 2011, the Preserve Association switched from being an HOA (Home Owners' Association) to being a POA (Property Owners' Association), each being viewed differently under Georgia law.
 In 2008 the Preserve became a recognized member of the national Firewise communities program and is one of the 13 in Georgia.
