Ask someone who lives in Spanish Peaks what the trail network looks like these days and you'll get two different answers depending on who's talking. One version describes downhill flow trails with near-1,000-foot drops, a color-graded Nordic network, and an adventure park with a pump track and zip lines. The other version, the one the club's own site actually lists under winter activities, mentions groomed Nordic skiing, snowshoe outings, and fat biking. Both versions are true. They're just describing different years.
In 2023, Lone Mountain Land Company hired the trail design firm Avid Trails to build a master plan for the 3,530-acre community. The firm spent more than a week on the ground auditing what already existed: just over 20 miles of trails, bike paths, and fire roads, some of it worth keeping, some of it flagged for reroutes or closure. From that audit came a second number that's done most of the talking since: 26 additional miles designed for the property, including three purpose-built downhill mountain bike trails, each dropping close to 1,000 feet, reached by a pedal-up climbing trail engineered at under 5 percent grade so the uphill doesn't wreck the point of the downhill. The plan also laid out color-graded Nordic loops (green, blue, black), dedicated snowshoe routes, ski-in ski-out connectors between neighborhoods, and an adventure park with a pump track, zip lines, climbing walls, and frisbee golf.
That's the plan. Here's what a resident checking the club's own current activities page finds listed as live today: Nordic skiing on the groomed network, snowshoe excursions, fat biking. No mention yet of the flow trails. No mention of the adventure park. The tennis and pickleball courts, part of the same infrastructure push, are already built and already in use, which tells you something useful: this is a company that finishes projects. It just hasn't finished all of them yet.
What 20 miles of existing trail actually gets you
The audit number matters because it's the baseline nobody talks about. Twenty miles is a real trail system, not a placeholder. It's what let Avid Trails route hikers and mountain bikers toward blue-ribbon trout streams, mountain top vistas, and remote campgrounds within the property before a single new mile got built. If you've been riding or walking Spanish Peaks for the past two seasons, this is almost certainly the network you've used, repaired sections and all.
The distinction is worth making because the marketing language around the master plan tends to collapse the timeline, as if 26 new miles and an adventure park arrived the same year as the audit. They didn't. The audit was the accounting. The 26 miles are the build-out, and build-outs on private mountain land, especially ones involving downhill-specific trail engineering and grade-controlled climbs, take longer than a single construction season.
The three flow trails: designed, not yet confirmed open
The most specific detail in the whole plan is also the most useful for setting expectations: three downhill-only mountain bike trails, each close to 1,000 vertical feet, built for beginner, intermediate, and advanced riders respectively. That's a real design commitment. A sub-5-percent-grade access trail for the climb back up is the kind of detail a firm includes when trails are genuinely slated for construction, not just sketched for a brochure.
But design documents and open trails are different things, and nothing in what the club currently publishes confirms these three lines are rideable this fall. If you've been waiting to hear that the advanced flow trail is open, the honest answer right now is that it isn't confirmed, and planning ahead of that confirmation means planning around the 20 miles that already exist, not the 26 that are still arriving.
Winter is where the plan already caught up to reality
Flip to the snow season and the picture changes. The club's own site lists Nordic skiing on a groomed trail network, snowshoe excursions, and fat biking as current amenities, which lines up with what the master plan called for: color-graded loops sorted by ability, dedicated snowshoe alignments, and neighborhood-to-slope connectors for ski-in ski-out access. Winter recreation at Spanish Peaks isn't a future promise. It's operating now, and it's the part of the 2023 plan that's furthest along.
That's a useful signal for anyone weighing how much stock to put in the rest of the plan. The winter infrastructure got built first, likely because it overlaps directly with the ski season that already drives most of the club's calendar. The summer-specific pieces, the flow trails and the adventure park, sit further down the priority list, which is normal for a phased build-out but worth knowing if you were expecting all 26 miles to show up at once.
Live now versus still on paper
| Amenity | Status this fall |
|---|---|
| Groomed Nordic trail network (green, blue, black) | Live, listed on the club's current site |
| Snowshoe routes | Live |
| Fat biking | Live |
| Tennis and pickleball courts | Built and operating |
| Riverside fly-fishing outpost | Live, part of existing clubhouse amenities |
| Three downhill flow trails (~1,000 ft drop each) | Designed in 2023 plan, not confirmed open |
| Adventure park (pump track, zip lines, climbing walls, frisbee golf) | Designed in 2023 plan, not confirmed open |
| Sub-5% grade climbing access trail | Designed alongside the flow trails, same status |
What the public trail next door shows about the timeline
For a sense of how long a well-used trail takes to become a genuine fixture, look just outside the gates. The Big Sky Community Organization's Mountain to Meadow trail, connecting the ski area to Town Center, opened in 2015 as a multi-use path and was quickly claimed almost entirely by mountain bikers, to the point that it's now treated as one of the defining rides in the valley. Eleven years turned a modest connector trail into a local landmark. That's not a knock on the pace of the Spanish Peaks build-out. It's context for how trail infrastructure actually matures once it's built. A flow trail that opens this year or next won't feel like a fixture immediately. Give it a season or two of regular use before judging whether it lives up to the plan that produced it.
What this actually changes if you live here
If your fall and winter plans have been built around the assumption that the full 26-mile expansion is already rideable, adjust that assumption now rather than after a wasted trip to a trailhead that doesn't exist yet. The 20 miles of existing trail, repaired and rerouted under the same 2023 plan, are your dependable network for hiking and mountain biking through the shoulder season. Once snow arrives, the groomed Nordic loops, snowshoe routes, and fat biking trails are confirmed and ready, which makes this the season where the master plan and the lived reality actually match.
For the flow trails and the adventure park, the honest position is to watch for an official opening announcement rather than assume a season. When a downhill trail engineered with a dedicated climbing access route does open, it will likely come with its own announcement given how specific the design work was. Until then, the version of Spanish Peaks you can ride is the smaller, older, already-proven one, and there's nothing wrong with that. It's the version that's actually there.
