I don't have $2 million laying around to spend on cool real estate around Twin Falls. Actually I just checked my wallet and I don't even have $2, but if I did have a ton of money this would be an awesome way to spend it. There's a big section of land for sale in the Snake River Canyon between Centennial Park and the Perrine Bridge and it includes part of the Mogensen Trail. Where Is The Snake River Canyon Land For Sale Located? The parcel of land for sale covers the entrance to the Mogensen Trail near the entrance to the Centennial Waterfront Parkway and includes 32 acres of canyon land and 1,900 feet of river front property.
