Steph C. on Blue Mountain Twin Summits Trail
Beautiful autumn foliage but covers the trail and makes for a slippery climb and descent. Great hike for groups. Lots of big rocks for climbing. The summit is a nice view. There is a beautiful lake and picnic area at the parking lot level. Good for dogs. Would rate intermediate difficulty in fall with leaves on ground. Likely easier in summer or spring.
As a Peekskill resident, Blue Mountain Reservation is a fun escape from the noises of the city and pace of modern life. I've hiked many of the trails and they can be a bit rocky. There are Mt Bikers, runners, and sometimes horses too. There is Verizon LTE for just about all of the park and Google Maps can guide you with a trail map otherwise the trail junction numbers are nonexistent. Blue Mountain has a nice view from the top and is an easy hike following the blue trail from the back parking lot.
