Getting There

The Sunset Ridge and Long Trail Loop is one of the most popular trails in the Underhill State Park. The Underhill Center and parking lot are right at the trailhead. The Sunset Ridge trail takes you to the highest peak of the park while the Long Trail loops along the ridge back to the trailhead. It's recommended by park staff to ascend the Halfway House Trail, traverse the Long Trail to the Chin (highest point in Vermont) and then descend Sunset Ridge. Halfway House is a steep trail, especially close to the Long Trail ridge-line, but has numerous switchbacks along the way. The Long Trail is all above the tree line and provides nearly 360 views of Vermont, Adirondacks, & White Mountains, but there's no shelter in bad weather (wind or rain). Sunset Ridge is a more gradual hike down, so it's less difficult heading down Mansfield; it also is above tree line for the top half and provides excellent views of the Champlain Valley and Adirondacks. The trail to the summit can be slippery and spikes are recommended. Other popular sites in the area are the Green Mountains, Cantilever Rock, and Pleasant Valley. Halfway and Sunset Ridge have Blue Blazes, while the Long Trail is White. It's best to avoid Yellow blazed trails because they are generally more difficult rock scrambles.

Trail Starts at Underhill State Park. Park here for a fee in Summer Parking on road only in winter about 1 mile down.

Having done this trail many times before, it was my first in the early spring and it was quite the challenge! We broke trail on Halfway House, hit LT, chin, down Sunset Ridge. Spikes highly recommended, quite windy at the top. Blazes much harder to navigate on the way up, causing us to meander a bit. A solid 5 hours of movement clocking just under 7 total miles.

Lots of snow but not too slick. Nice temps but a little windy up top. Micro spikes highly recommended.

My friend and I went in March and the conditions past tree line are very dangerous because the snow is very deep and we kept falling into it. Come prepared!

Great hike! The views were incredible. Hiked on 12/23 and there was a lot of snow. Micro spikes are a must, I don’t really think you would need any other equipment. Be careful once you go past tree line, the trails were poorly marked once you got up there. Other than that, it was incredible! Not too steep, very little climbing required. Definitely recommend!

I was lucky to get there in the afternoon because morning was foggy with a lot of ice and snow at the top (on 10/17). By afternoon, the Sun came out and the view was gorgeous at the top. The melting snow made the trail wet and slippery. There was a steep rock where I thought I will have to go back. Someone offered to give me a hand and literally pulled me up. Wouldn’t have made it to the summit without that stranger who offered to help, so thankful!

Loved this hike. We went up sunset ridge and down halfway house. Halfway house has a couple of slippery spots so wouldn't advise that direction unless your shoes have decent traction (hard to imagine being able to climb HHT without getting your feet wet so would advise waterproof shoes or an extra pair of socks). Little bit of ice near the summit on 10/11.

HikingFeeGreat!RockyScramble

This trail was absolutely PACKED with people, but what can you expect on a beautiful Saturday in fall? We did HHT up and Sunset Ridge down and I think that’s the best option for this loop. It’s narrow, rocky, and sometimes slippery on HHT but it makes for a fun ascent. Sunset Ridge is gorgeous with many expanses of flat, steep rock that I imagine would be very tricky to traverse if it were wet. This is a great loop trail overall. The most challenging part is having to try to hide your annoyance when you get to the top and it’s packed with people who drove up or took the gondolas.
