There is a private land owner that plows a road out to Indian point. I have been using there road for the past several years and it is maintained as good as the resort roads. I believe the cost was $10 last year and they may sell a season pass. They also maintain a bridge to get over the pressure ridge that forms every year. At mile post 222 (just past Eddies on 169) turn right and then take a left at the lake and it is right there. Good luck.
