Where Pinewood Springs Walks the Dog Once the Winter Gates Close

Four public land managers surround Pinewood Springs: the U.S. Forest Service, the City of Longmont, Larimer County and Boulder County. Each one publishes its own winter dates. Between the last day of November and the middle of January, those dates cut off trail access one piece at a time. Dog rules had already ruled out about half the nearby trails before any of the dates arrive. If you walk a dog, your winter map comes down to a short list of trailheads along US 36 and one mesa east of Lyons.

The Order the Gates Close

Here is the published schedule for the trails closest to the neighborhood, starting with the first closure:

1. November 30. The Forest Service lists a tentative gate season of June 15 to November 30 for Johnny Park/Button Rock Road, FS 118. It also notes that actual gate dates depend on conditions.
2. December 1. The City of Longmont closes the northwest corner of Button Rock Preserve to recreation. That closure covers Cook Mountain Trail and the preserve access from Coulson Gulch Trail. Access returns April 1.
3. Mid-December. Larimer County describes Hermit Park Open Space as open "March through mid December." The county's campground page gives a seasonal closure of Dec. 20 to March 1, weather dependent.
4. January 15. Boulder County lists a prescribed-burn window of Jan. 15 to April 15 for the Nelson Loop at Hall Ranch. The park closes on ignition days. The page doesn't say which year that window applies to.

None of these dates is set by a snowfall. Each one sits on a different agency's calendar. Conditions can move the FS 118 gate and the Hermit Park closure, and snow and mud can close other trails sooner, but each agency sets its baseline date in advance.

Why the Coulson Gulch Door Closes First

Coulson Gulch is the closest of these trailheads to Pinewood Springs by road. The Forest Service gives directions from Lyons: 9.5 miles west on US 36, then 3 miles on Larimer County Road 47, then southwest onto NFS Road 118. The trailhead is immediately on the left after the road crosses the cattle guard. The trail is Forest Service #916, which the agency describes as "well-maintained" and 1.8 miles long. It drops south to Higgins Park and meets Button Rock Road there. Heading east from that junction takes you into the city preserve and on toward Ralph Price Reservoir.

According to the Forest Service trailhead page, dogs on Coulson Gulch must be on a hand-held leash. Dogs have never been allowed past that eastern junction since the rule changed in 2023. Longmont banned dogs at Button Rock effective May 15, 2023, citing the watershed, ecosystems and wildlife health of the preserve. On Dec. 1, the preserve end of Coulson Gulch closes to everyone else as well.

Longmont's seasonal closure notice explains why. Elk, deer, moose and bighorn sheep spend the winter there on what the city calls a "starvation diet of dead plant material," and the closure gives them space from the added stress of human contact.

There's one open question about the road. The FS 118 gate season ends the day before the preserve closure starts. The Forest Service pages don't say whether that gate sits before or after the Coulson Gulch Trailhead. Check the Arapaho and Roosevelt current conditions page before you drive up in December.

The Dog Rule Narrows the Map Before Any Date Does

Dog rules sort the nearby trails before any closure date takes effect. Here is how the closest options compare, using each land manager's current pages:

Button Rock's east side really is open all winter. Longmont's 2023 management plan lists Sleepy Lion Trail and its extension at 2.5 miles, along with the short Hummingbird Switchback at 0.2 mile. Hall Ranch has Bitterbrush at 3.7 miles and Nighthawk at 4.7 miles. All of that mileage is off-limits to a dog all year. Strike those rows, and the winter options with a dog come down to three Forest Service and county trailheads plus Rabbit Mountain.

Homestead Meadows, From Two Directions

Two of those trailheads lead to the same place. Lion Gulch Trailhead is on the south side of US 36 at mile marker 8, 7 miles east of Estes Park and 13 miles west of Lyons. The lot holds about 35 vehicles. The Forest Service says the trail drops abruptly at first and then climbs three miles along the stream to Homestead Meadows. Visiting all the homesteads adds another 2.8 miles. Dogs must be on a hand-held leash.

Hermit Park Open Space, about two miles southeast of Estes Park at 7,880 to 8,964 feet, also reaches the meadows. Its Homestead Meadows Trail continues onto adjacent Forest Service land as Trail 971. Kruger Rock Trail inside the park is hiking-only. Leashes can be no longer than 10 feet, and pets can't be left unattended. On the county's current fee page, a daily vehicle permit costs $10 and is good for 24 hours. Annual permits are $100 for residents, $130 for non-residents and $70 for seniors. The fee page doesn't show a publication date, so confirm rates before you go.

From the start of the Hermit Park closure until March 1, the meadows can be reached only from the Lion Gulch side. That makes the mile marker 8 lot the single Homestead Meadows trailhead along US 36 through the coldest part of the season.

Larimer County lists 13 camper cabins at Hermit Park. For November, December, March and April, the rate is $90 a night on weekdays and $115 on weekends, with a two-night minimum. Those rates are an option for houseguests in early December, before the closure.

East of Lyons, on a Leash

Rabbit Mountain is the one Boulder County property on this list where dogs are allowed, on leash. It has three routes: Eagle Wind at 2.5 miles, Indian Mesa at 2.2 miles and Little Thompson Overlook at 1.5 miles. Boulder County parks are open sunrise to sunset, and parking is not allowed between sunset and sunrise. That rule matters in December, when daylight is short.

Rabbit Mountain also closes for mud. A May 5, 2026 county notice temporarily closed Eagle Wind and Little Thompson Overlook, every Hall Ranch trail and five Heil Valley Ranch trails, with reopening dependent on conditions. As of Oct. 9, the county's closure list named only the Wally Toevs fishing pier at Walden Ponds and Meadowlark Trail at Coalton Trailhead. The Boulder County trail closures page shows the current list before a drive down the canyon.

Closer to town, the Town of Lyons lists a dog park among the facilities at Bohn Park. The town's current dog park page didn't load during our research, so check hours with the town directly.

The Drive Home After Dark

Winter outings in Lyons often mean driving US 36 after dark. Colorado Parks and Wildlife names Highway 36 between Boulder and Lyons as a high-risk route for wildlife collisions. CPW says winter migration raises that risk, especially between dusk and dawn.

Several dates on the Town of Lyons 2026 event calendar fall right in that window:

• Oct. 24: Halloween Spooktacular downtown, with a costume parade, trick-or-treating and children's games.
• Dec. 4, 5 to 7 p.m.: Downtown Lighting Ceremony.
• Dec. 5 and 6, 10 a.m. to 4 p.m.: Artisan Market.
• Saturday, Dec. 5, 6 p.m.: Holiday Parade of Lights.

The lighting ceremony is three days after Button Rock's northwest corner closes, and the parade comes the following night. That weekend, a morning walk at Lion Gulch or Hermit Park still fits into the same day. Hermit Park, if the county's Dec. 20 date holds, has about two weeks of its season left by then.

We've lived and worked in the Estes Valley since 1995, and these seasonal dates come up for us every year. If you'd like to talk through what owning along the US 36 corridor looks like in winter, from trailhead access to the drive down to Lyons, the team at Estes Park Team Realty is happy to help.
