Trail: Pine Bend Brook Trail, Mt. Tripyramid Trail
Conditions: Dry Trail, Wet Trail, Mud - Minor/Avoidable
“I started early to try to beat the heat but still looked like I had jumped in a lake by the time I hit the first peak. The trail is mostly dry with some wet areas. Most of the mud is supportive but there are some mud pits that are not. There are rocks or logs in most of them to allow for dry feet. The steep section up Pine Bend was fairly dry but the humidity did add a few slick areas. Between the 2 peaks was dry with good footing. The trails were very quiet today. I only saw 3 people all morning. Even with the heat, this was WAY better than sitting on the couch!”
Trail: Livermore Road, Mt. Tripyramid Trail
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Mud - Minor/Avoidable
“It was a beautiful day up on the slides of the Tripyramids, taking in the views. I hadn't been this way in over 20 years. It was time to come back so that my son could bag some 4Ks and I could remind myself what this trail entails. Honestly, the first time I hiked it, was in the South to North slide direction, i.e., the NOT recommended direction. I did fine. This time we did it the recommended way. It was also fine. Both slides are tough, but manageable and indeed offer fine views. We had fun identifying our favorite peaks. The trail in between the slides was lovely and pleasant to traverse. This hike finished August for me. Meanwhile, my son got his 21 and 22 4K as well as two more Terrifying 25 trails. Lots to be proud of today.”
Trail: Livermore Trail, Mt. Tripyramid Trail, Kate Sleeper Trail, East Sleeper Spur, Rollins Trail, Downes Brook Trail
Conditions: Dry Trail, Wet Trail, Standing/Running Water on Trail, Mud - Minor/Avoidable
“Livermore trail was mostly very gradual, especially once we hit the road section. There was some deep mud but it was avoidable. Mount Tripyramid trail was nice and dry, and climbing the north slide was just as beautiful as when I did it in May. It was very dry so we could pretty much just march right up the middle of it. Kate Sleeper trail was well maintained and easy to follow. Near South Tripyramid, you descend a similar slide to that on Mount Tripyramid trail, which is loose and gravelly. East Sleeper spur is a little tight but easy to follow, and there is a small summit sign on the wooded summit of East Sleeper. Downes Brook trail is a bit overgrown up top, but it widens in the lower forest and is very wide and smooth. The brook crossings (which there are at least seven of) could be tricky in higher water, but that was not an issue at all and all crossings were easy to rock hop. The weather was absolutely gorgeous and felt like fall! Cool, crisp air with a nice breeze too. I could not have asked for a better day.”
