A rare opportunity to own two contiguous parcels in The Peninsula at Mystic Shores — 144 Serene (~6 acres with residence) and 138 Serene (~4 acres) — delivering ~10 acres and approximately 1,200+ linear feet of Canyon Lake shoreline spanning the main shore and cove (buyer to verify). Together, the property offers unmatched privacy, water access, and lifestyle, with a private on-site boat launch/ramp. The main residence showcases soaring 24-ft beamed ceilings, an open layout filled with natural light, and wall-to-wall windows framing panoramic lake views. The chef’s kitchen with double ovens and custom cabinetry flows to casual and formal dining and expansive outdoor living with a kitchen and fireplace. The primary retreat offers a stone-clad fireplace, spa bath, and water panoramas. Two main-level offices, plus upstairs media and game rooms with wet bar, ensure year-round enjoyment. Outdoors, an infinity-edge pool with rock waterfalls anchors the setting, with a gently sloping lawn to the water’s edge. An attached four-car garage includes a covered boat bay and workshop. A private irrigation well and high-speed internet provide modern convenience. Adding the adjacent 4-acre tract expands your usable shoreline, increases privacy, and opens possibilities for future amenities or guest quarters. Ownership in Mystic Shores includes a 26-acre lake park with resort pool, tennis & pickleball, sand volleyball, trails, and more.
