Liz and I hiked BreakNeck Ridge for the second time as part of our Kilimanjaro training regimen. The loop starts and ends in Cold Spring, NY. It is a very beautful 6 mile loop that takes around 4 hours. The first first shot up from the river is extremely steep and reaches around 1,300 ft. in short order.
you can kind of see how steep...
