Two miles of mountaintop resembling a sleeping giant give this park its name, and make it a distinguishing feature on Connecticut's skyline

Rocky surface thought on dogs feet ... always a great workout up hill

I've been hiking this Trail for years. it never ceases to amaze me. It calls to so many people that travel it each week. this is a picturesque hike for sure. there's plenty of mountain laurel and different trees and flowers. The road is wide and can accommodate many people. I've seen this Trail designated as easy and I would say yes it's easy because it's a road but it is at an incline so for some people it might not be easy because of it being at an incline the entire way. There's nothing tricky about the Trail.

The blue trail is challenging for moderate/intermediate hikers. You must be extremely careful climbing up a rock face that’s slippery on some parts. You will be rock scrambling on the blue trail. If you are unfamiliar with rock scrambling, look it up before you decide to take the blue trail. Do not attempt this trail alone. Be sure to give climbers space before you go up to avoid falls.

Beautiful trail and well marked

This trail is no longer closed.

A classic. Not difficult in terms of skill, but it’s solid cardio your calves will feel. I will do this about 30 times a year, now that reopened.

Not very many views from the main tower trail but it was also a very foggy day. The tower was absolutely stunning and well maintained, not sure if it was damaged from the storm at all but couldn’t tell if it was! Going up wasn’t challenging as it’s entirely a gravel path but it’s 1.7 miles completely uphill with some steep parts. With the humidity mixed with my sweat I was drenched when we got to the top. For some reason there wasn’t a single mosquito out. I’ll have to check out some other paths next time!

Good Hike. A word of warning. There are technical bits on this trail. Especially at the beginning. It has greay scrambles and gets the climb out of the way early. However, it is strenuous. Use due caution and keep to your own comfortable pace. Not the best hike for new hikers. ***15$ Charge for out of state cars.**

This trail should NOT be rated moderate. It is extremely easy, as it is basically a gravelly road that climbs up the mountain to the tower. Anyone that is able to walk can walk up this trail. It is a beautiful walk though, and I always take it down from the tower after I take the much more challenging blue trail up.

The park is back open as of today! It was great hiking up the blue trail to the tower. I had forgotten how hard it was but the payoff is so good. The blue trail is not an easy hike for out of shape or uncoordinated hikers, as it gets steep and has big rocks and big steps to climb. But most kids and people can do it. I end up using my hands a good way up the head. Because it is so steep going up, I usually take the tower trail back down. It takes me about an hour from the parking lot to the tower on the blue trail, and 30 minutes back down the tower trail.

Sadly the trails are closed until June 21st, pending official word. When given the opportunity, this is a must hike for anyone who loves challenging rock climbs. The scenery is breathtaking in any season. I’ve been hiking here since I was a kid and it is by far one of the best hikes in CT. Views of QU and Long Island sound can be seen from different viewing spots of the mountain. The tower is nothing special but could provide an ideal spot for a rest or picnic. The main trail is better suited for dogs and younger children.

Trails seem to be in good shape since clean up from the tornado. Because it’s technically closed the trails are empty and that’s definitely not a bad thing

Trail was very secluded and not too occupied. Wear supportive shoes because of rocks and sharp incline/declines

Badly marked trails, only the first twenty mins is hard, criss crosses over the same path

Beautiful scenery! I’ve hiked sleepy giant three times.

I went to hike this last week & found out that the trail has been closed since a tornado hit it earlier this year.

We took this trail a few years ago in the summer. Ended up going up some additional trails after we came part of the way down from the Tower. Nicely blazed, great views. Can be crowded.

Love it. The Tower is the best part.

Easy hike but watch for copper heads in the summer. Also good for running if you want a challenge

Great place to hike. Been a few years ago. I wanted to go back this summer but unfortunately it’s closed due to storm damage

Great hike! I took my kids (ages 11 & 9) up to the head in the fall. They were a little nervous in some spots, but it was worth the view from the top.

Great hike. Has a couple of challenging-ish parts. There are some beautiful views. It’s a nice relaxing hike that took about 3.5-4 hours. If in the area, I’d do it again.

This park has stunningly beautiful vistas and trails. It is not for the weak of heart if do the Blue Trail - it is crazy steep but you feel like you've accomplished something when you get to the top. If you stay on the outer edges for the whole park you will find pretty and quiet paths. towards the center of the park it's very well-traveled.
