Great morning getting to know my coworkers outside of the office. Heavy traffic on the trail this Sunday morning but everyone was respectful. Beautiful spring weather and friendly dogs on the trail.

Hills, hills and more hills. I went counterclockwise on the loop and it was a great workout for how short the hike is in miles. Plenty of parking.

Great exercise! Nice to see people (and dogs) of all ages enjoying a good climb. Going up to the right will have a paved road in portions and is a bit longer to top. Taking the loop to the left is steep & rocky, but a bit shorter. We went to the left and liked our journey.

Running

Lots of cars in the area but it didn’t feel like a lot of people on the trail. Decided to run this trail, and went counterclockwise this time around. This was a long, steep and steady climb - LOVED IT!! Go early because there is NO SHADE and it can get VERY HOT later in the day. Definitely one of my favorite local trails to hike and/or run.

HikingGreat!

Steep hike but well worth it once you reach the top!! The views as you make your way up the trail are amazing! Best to do early morning when it’s cooler, trail is not shaded.

This was a beautiful hike with stunning views. Being from NYC I really appreciated the subtle 9/11 tributes on the emergency markers noting how many “floors” you climbed (only on the first part of the trail if you go clockwise at the start of the loop). The loop’s views from all angles is beautiful. It is close to the hwy and you can definitely hear it, but with some personal music or a partner it’s not that noticeable.

Did entire loop..... steep/rocky switchbacks/ and hilly, great workout! Take water! Hiking sticks help especially coming down hill.

HikingGreat!No shadeRocky

I did the loop clockwise. It was a very rocky hike. There is no shade, but luckily it was cloudy this morning and we got no sun! It was not an easy hike. Incline all the way up. Even though it was a relatively short hike, it felt long.

Great incline with a rugged but very navigable pathway. Hiking boots recommended but not vital. Hat needed on sunny day... absolutely no shade.

I’ve done this trail many times. It’s a great workout especially if you stay to the right at the fork in the road. Very rocky in certain area’s. There’s not a lot of shade on sunny days but today was nice and cool.
