3450 West Portal Rd, Grand Lake, CO 80447
About this home
1.7 acres, located at the east end of Grand Lake near the Adams Tunnel & boat launch, on the once-106 acre site that was originally homesteaded by Minnie Harmon in 1896. With all of this space comes easy year-round access, flat and accessible terrain, lots of parking and storage inside a 4-car garage plus carport for your boats & toys (which is rare for many lakefront homes), and over 200 feet of private shoreline comprised of two parcels upon which you could build a second home and dock or boathouse. This home is protected from other neighbors, bordering 800 feet of undeveloped shoreline, where the next home is about 800 feet away, and a rock outcropping hides this beautiful home from the neighbor to the west. The home was completely rebuilt in 1992, and the fireplace of Minnie's home still stands in the living room today. About a half mile walk from your doorstep to Adams Falls. Great entertainment areas, inside and out... 3 Separate areas for having company stay over, with privacy for all. A huge amount of parking is one of the most wonderful features: the home is almost all on one level and you can walk to the 200 feet of water frontage with effectively no stairs. What other lakefront property offers all of this? R182701 3450 West Portal Road $3,750,000
