It was about 16 miles round trip to hike to the summit and visit some view points.
14.3 miles one way, hiking up Schnebly Hill Road to Munds Mountain then down Jacks Canyon. 7:30 to 3:00. See trip report.
You can get to Lee from Munds, but it's a bit of a scramble in a spot or two. Still if you're comfortable on 4th class or so it shouldn't be a problem for you. There may even be an easier route, but that was the one I found.
A lonely afternoon exploration from my house in Munds Park. I seem to remember being able to park near the radio tower dealie off of Schnebly Hill Rd., but I may be mistaken or that road may closed since the late 90s. it might be worth somebody's time to explore as far south on Munds Mtn as you can go, possibly some good views to the south and maybe a route up onto Lee Mountain?
Climbed this in the early morning hours as I had to work a 12 hour shift later that day. Pretty level approach until about the last 1/2 mile or so.
