Situated on an expansive 10,000 square foot lot, 70 Canyon Lake Drive is surrounded by mature trees and green hills offering excellent privacy. Exterior features of the property include a large pool with a built-in spa, outdoor dining, multiple lounge areas, built-in BBQ, gas fireplace, and landscaped gardens.
