In East Vail, Winter Starts on the Bighorn Sheep's Schedule

Vail Mountain's opening day sets the winter calendar for most of the valley. East Vail's comes earlier and is set by the herd. In November and December the bighorn sheep come down to the slopes north of North Frontage Road to mate. Habitat crews then wait for enough snow to burn slash piles at the Booth Creek and Bighorn Creek trailheads. In mid-December the Town's winter bus schedule starts running East Vail buses every 10 minutes. All three of those dates trace back to one decision. The hillside above the neighborhood is now permanently protected, closed to the public, and managed for the sheep.

A Hillside With No Public Access

The slopes the herd uses through winter now make up the Vail Bighorn Preserve. Eagle Valley Land Trust describes it as 146.9 acres across four Town-owned parcels north of North Frontage Road. The Land Trust holds a conservation easement on the land, and its listing gives public access as "None."

Before the preserve, most of this ground was headed for development. As Vail Daily reported, the Town paid $17.5 million for the former Booth Heights site, which covers the 5.4 acres Vail Resorts had planned to build on plus its 17.9-acre open-space parcel. Those were combined with two Town parcels of 93.3 and 30.2 acres, and Eagle County's Open Space Program put in $5 million. The recorded easement bars development, and the restriction binds any future owner.

The easement also controls who can use the land and how. According to the same Vail Daily report, it prohibits recreation and any landscape change that could harm habitat. Wildfire mitigation and maintenance of some existing berms are allowed. The Town is required to prepare a land-management plan, and Eagle Valley Land Trust monitors the property every year. In practice, the slope above the frontage road is land residents can see from the road but not hike. The sheep have it to themselves.

November Is When the Herd Comes Down

The herd uses this ground because of the terrain. Eagle Valley Land Trust's account of the preserve's protection says it protects winter habitat for a subpopulation of the Gore Range bighorn herd. The sheep rely on its sunny, south-facing slopes for winter forage and mineral-rich soil.

The Land Trust's 2026 explainer on bighorn ecology says bighorn move to lower elevations in winter and mate in November and December. That is also when they are most likely to cross paths with people. So the herd is closest to the neighborhood at the same point in the year when the preserve's no-entry rule matters most.

The number of sheep is the reason the Town has invested so much here. Vail Daily reported that the herd fell from about 125 animals in the 1990s to 41 in 2019. The area has been identified as critical winter range for Rocky Mountain bighorn sheep.

For viewing from the road or a bus window, Colorado Parks and Wildlife's general wildlife guidance applies. Don't feed or approach wild animals, watch from a safe distance, and back away if an animal seems nervous.

The Habitat Crews Work the Same Slopes

Protecting the land was the first step. The Town has since started actively improving the habitat. In March 2026 the Vail Town Council voted unanimously to partner with Colorado Parks and Wildlife on the Booth Creek Fuels Reduction Project, a multi-year effort covering more than 3,600 acres in the Upper Gore Creek watershed. Vail Daily's coverage of the vote lists the project's goals as restoring habitat, improving movement corridors, and opening up sight lines so the sheep can spot predators.

The plan calls for hand thinning, mechanical treatment, and prescribed fire across roughly 3,000 acres. Funding totals nearly $400,000. Colorado Parks and Wildlife secured $300,000 from the state's Auction Raffle Program, and the Town committed $100,000. The work is split into nine treatment units and is scheduled to run from May 2026 through June 2027.

Summer was mostly machine work. The White River National Forest announced in June that crews would treat 86 acres in Unit 104 near Spraddle Creek. Machinery would be on Spraddle Creek Road for most of the summer, and the road would stay open to nonmotorized use past Vail Stables.

Winter work is burning the piles that thinning left behind. In its October 30 release, the forest listed two East Vail trailheads among its Eagle County sites for this fall and winter:

• Booth Creek Trailhead: 22 acres
• Bighorn Creek Trailhead: 4 acres

Burning depends on conditions. The release says it begins once snow cover is adequate and the weather cooperates, and it may continue into spring 2027. Firefighters check conditions in the hours before each burn and cancel if conditions turn unfavorable. Most of the smoke clears during the day, but some can settle in valley bottoms and drainages overnight for short periods. Crews monitor each site for several days after a burn. Notices for specific projects go out on the White River National Forest website and the forest's Facebook page.

The Booth Creek Trailhead area had already seen restrictions this year. A Town of Vail notice closed parking at the Booth Lake Trailhead starting May 31 and running through the fall. It also banned parking in the surrounding neighborhood and at Booth Creek Park. Drop-off and pick-up were still allowed, and the free East Vail bus served the trailhead.

The Frontage Road Gets a Bus Every 10 Minutes

The free East Vail bus already stopped at the Booth Lake Trailhead while its lot was closed. If people can't park at the trailheads and can't walk into the preserve, the frontage road is how they move through the neighborhood. This summer, more of them did it by bus. On October 7 the Town of Vail published summer ridership under its enhanced schedule, which started June 8. East Vail had the biggest increase in raw boardings of any outlying route.

East Vail's increase came after the East Vail Express was discontinued. Even if every one of the Express's 14,640 boardings in summer 2025 had moved to the regular route, that would explain only about 60% of the 23,707 added boardings. The Town says the summer changes were the biggest overhaul of its routes and frequencies in more than 30 years. They added service on every outlying route between 6 a.m. and 8 p.m., funded in part by a Colorado Clean Transit Enterprise grant.

Winter goes further. According to the same release, the winter schedule keeps the summer improvements and increases East Vail service from every 20 minutes to every 10. It also brings back extra seasonal Ford Park service during the morning and afternoon peaks. The summer schedule runs through mid-December. The current East Vail schedule lists stops at Booth Falls, Pitkin Creek and Bighorn Park, so the stops nearest the treated trailheads will see twice as many buses an hour.

Grid schedules are posted in the bus shelters and available in print at the Vail Transportation Center. ride.vail.gov shows where each bus is in real time and how full it is. Once the winter schedule starts, a rider at the Bighorn Park stop can check the tracker before leaving home and expect a bus every 10 minutes.

The Booth Creek project is scheduled to finish by June 2027, and Eagle Valley Land Trust will keep monitoring the preserve under the easement each year after that.

The preserve and the protected slope behind it are now a permanent part of every East Vail property's surroundings. If you'd like to talk about how that shapes owning, buying or selling in the neighborhood, Ron Byrne & Associates would welcome the conversation. Schedule a Private Consultation.
