Easy on the Eyes and Legs
OK, Your whole trip is only about 656 miles over three days, so you'll have lots of time for those scenic drives and hikes. All of the places you list are well worth seeing. After Blue Mountain Lake, I think my preferred plan of attack would be to hike Ausable Chasm and then take a scenic drive generally along the Lakes to Locks Passage down the Hudson River Valley stopping at some of the old pre-Revolutionary forts on the way, such as Fort Ticonderoga and Crown Point.
