Blue Hills Reservation Skyline Loop Trail Guide; 3 Miles

Challenge yourself with this short but mighty hike just south of Boston in Blue Hills Reservation, complete with steep scrambles and sweeping views from multiple hilltops and the historic Eliot Tower! A great test run for some of the bigger hikes in New England. 

Located just 12 miles south of Boston, the Skyline Trail is part of the 7000-acre Blue Hills Reservation—the largest park, and one of the oldest, in metropolitan Boston. This hike offers a scenic mountain-like experience while being relatively close to the city.  

In this post, you'll find everything you need, including parking information, trail highlights, and turn-by-turn trail directions to help you have a fun and successful hike.

Though the distance is short—just over 3 miles—don’t be fooled! It packs in a solid workout, with rocky ascents and technical scrambles that make it a fun and challenging hike for active dogs and humans alike.  

Living next door in Connecticut, I love taking day trips to Massachusetts to go hiking. While I usually opt for a hike in the Berkshires, I've been discovering more and more hikes just outside of Boston that I love - including this one!

So let's get to it and check out everything you need to know for this hike at Blue Hills! ⬇️🥾

🌟Great Blue Hill Skyline Trail Loop Details

Blue Hills Reservation is home to towering eastern white pines, oaks, and hickories—many of them well over a century old. On this hike, you’ll find multiple hilltop views, lots of elevation change, and nearly 360-degree views from the historic, stone Great Blue Hill Observation Tower, also known as Eliot Tower.

Parking Tip 🚗

One challenge to keep in mind is the limited parking for this trail: we were there on a rainy Saturday in June and found a spot, but there’s only room for fewer than 10 cars. The Blue Hills Reservation website notes to expect heavy use on weekends, so get there early!  

Hiking with Dogs Tip 🐶🐾

Several times on the scramble sections, we had to drop the leash to use our hands to navigate up or down, and saw others doing the same. According to a local hiker we met along the way, about 90 percent of dogs on this trail are off-leash, and most owners are friendly and respectful.

🌲 Skyline Trail Overview 🌲

Begin at Houghton’s Pond main parking area along Hillside Street right across from the MA State Police station and the DCR State Parks South Office. Carefully cross Hillside Street, heading north on the crosswalk, following the blue-blazed N Skyline sign. 

Once across the street, find the trailhead 200 feet up the driveway and to the left of the DCR building. Begin the loop counterclockwise, following the blue blazes and Skyline Trail signs (which you’ll stay on for most of this loop). 

From the start, the trail climbs quickly up to Hancock Hill (509 feet) and Hemenway Hill (473 feet) where rewarding vistas await. After taking in these early views, continue following the blue-blazed N Skyline Trail to Great Blue Hill signs. 

At 1.4 miles, arrive at Eliot Tower, which is named after Charles Eliot, a visionary landscape architect who helped establish the Blue Hills Reservation and the Metropolitan Park System of Greater Boston. Walk up a few staircases and take in panoramic views of the Boston skyline, giving thanks to the man who “sought out hill, forest, shore for all to enjoy.”  

From here, follow the blue-blazed South Skyline Trail as it loops around the Blue Hill Observatory and Science Center (open weekends 10 a.m. to 4 p.m.) before heading back down to the parking lot.
