I believe it's paved all the way, just steep.......unlike Pike's Peak. Anyway, shouldn't be a problem for a Jeep. I'm pretty sure "Soccer SUV's" go up and down it all the time. Have fun and enjoy the country!!! Upstate NY, VT, NH, and Maine are beautiful places. While you're up there, check out Jackman, Maine.........not all that far from Mt. Washington!!
