We went up from the south trail. Plenty of parking on both sides of the road. The trail is well maintained and snakes up the mountain. Some steep parts, but you have to get up the mountain some way. Beautiful lookouts along the trail and at the top. Worth the trip.
I did the "Round the Pond" trail to the "Gnome Stairs" trail. It's an easy couple miles (maybe even less). There are beavers in the pond, and the "Gnome Stairs" were pretty cool (man made stairs leading down into Wheeler Brook). The trail ends at a "Trail End" sign. Just follow the blue dots.
Great hike. I haven't been hiking in New England before but really enjoyed this. At 52 with bad knees it was a challenge but doable. I now feel more of a kindred spirit with my uncle who helped maintain Appalachian trails in Mass before his passing while doing trail maintenance...
