Build your dream home on this 1.04-acre corner homesite tucked into the gated Rio Central section of Mystic Shores, one of Canyon Lake's premier communities. Underground utilities are already in place, giving you a head start on construction. The lot's mature tree cover offers natural privacy and shade while still leaving room to design your ideal floor plan. As a Mystic Shores resident, you'll have access to a full slate of resort-style amenities: a community pool, tennis and basketball courts, sand volleyball, a boat ramp, fishing access, and miles of walking trails throughout the neighborhood. The community sits along the Guadalupe River and the north shoreline of Canyon Lake, offering that classic Hill Country lifestyle just minutes from FM 306. Note: all new construction is subject to Mystic Shores POA architectural review and deed restrictions — buyer to verify specific building requirements, water source, and utility details directly with the HOA prior to purchase.
Mystic Shores, located between Canyon Lake and the Guadalupe River, is a hill-country and lakeside Canyon Lake neighborhood with limestone bluffs and big-sky views. The mood concentrates around the Mystic Shores POA waterfront park and boat ramp, where kayaks, fishing lines, and sunset watchers set the pace. Homes lean Texas Hill Country—stone accents, metal roofs, deep porches, and long driveways that follow the terrain. The landscape reads as cedar, oak, and rocky outcrops, with winding roads that open to water glimpses. Nearby, the Whitewater Amphitheater and the Historic Gruene Hall anchor live-music nights, while The Gristmill River Restaurant & Bar keeps the riverfront table scene classic. Days often revolve around lake time, trail walks, and quiet stargazing after dark.
