Sugarloaf Mountain Loop (Maryland) Hiking Guide
Sugarloaf Mountain rises about 800 feet above the farmland south of Frederick, a monadnock left standing after the land around it wore away. A nonprofit, Stronghold, owns it and keeps it open to the public. This long loop climbs to the summit crag early, then wanders the quieter northern peaks to White Rocks before circling home.
The Loop
Hiking Project's Sugarloaf Loop runs 7.6 miles with 1,180 feet of climbing from the main entrance on Comus Road. It links the White (Mountain Loop), Orange (Sunrise), Red (Monadnock) and Blue (Northern Peaks) trails, and puts the steepest work in the first mile and a half, up to the summit. After the top, the Blue Trail carries you north to a five-way junction near mile 3, then west over a short rise to White Rocks, a good lunch stop well past the summit crowds.
A Shorter Option
If you only want the top, drive up to one of the parking areas higher on the mountain and walk the short summit circuit, which Hiking Project measures at 1.1 miles with 290 feet of gain. Stronghold puts the summit at 1,282 feet. Expect company at the crag on any nice weekend.
Gate Hours and Parking
The entrance gate opens at 8 a.m. and closes at 4 p.m. year-round, and no one may park on the property after 4. Everyone must be off the mountain by sunset, and cars left past then are towed at the owner's expense. Roadside parking is banned, and so is parking in the crossroads at the foot of the mountain. The exit road has one-way traffic spikes and the property has security cameras, both added after a 2023 break-in attempt closed the mountain from August to October that year.
Private Land, Public Welcome
Stronghold gets no government money; maintenance runs on a trust fund, memberships and gifts, which is why it asks visitors for a $5 donation. There are no trash cans, so carry out what you bring, and use the portable toilets Stronghold provides. Fires, alcohol, camping and firearms are not allowed. Horses are limited to the yellow trail, and Stronghold asks hikers to stay off the trails right after rain.
Dogs and Snakes
Dogs are welcome on a leash at all times. Stronghold warns that the mountain is home to timber rattlesnakes and copperheads, so watch where hands and paws go on the rocky summit trails in warm weather. Black bears, foxes and coyotes also live here, along with pileated woodpeckers and wild turkeys.
