Sphinx offers 20-acre lots with access to the Madison River through a strip of BLM land, spectacular views and wide open spaces. They are also the least expensive 20-acre parcels in the Madison Valley. Ideal for an "off-the-grid" cabin as power is only at the highway. There is no HOA at this time but there will be when the majority of the lots are sold. All lots will require wells and septic systems, with well depths in the area ranging from 96' to 370'. Three Rivers Cooperative will be providing phone and fiber optic cable to every lot in 2020. Covenants require 1,200 SF of living space, no modular or manufactured and no more than 7 acres may be permanently fenced. Sphinx subdivision is strategically located in the middle of the Madison Valley with abundant access to hunting, fishing, snowmobiling, trail riding, hiking and exploring in the many mountains, rivers, lakes, and public lands. Sphinx is just 15 miles south of Ennis & approximately 1-1/2 hours to the Bozeman Airport.
