Tahoe and Truckee
Start here for the current model at Loam's Tahoe/Truckee location. It cannot describe every elevation or shore of the lake. Use TAMBA's individual trail reports to plan a specific basin ride.
Best bets right now: Tahoe and Truckee, Auburn and Folsom foothills, Nevada City and 1 more.
7 of 7 networks rideable across 5 riding zones
Rideable means PRIME or DUSTY. These estimates use weather, soil, and terrain data. Check each network for details and closures.

Compare Tahoe and Truckee conditions with lower Sierra foothill alternatives. Elevation, snow and access matter as much as the forecast when choosing where to mountain bike.
Tahoe coverage is still broad: the Tahoe/Truckee entry is one modeled location, not a report for every trail around the lake. The other entries below are separate Sierra foothill destinations. Use TAMBA for individual Tahoe trail reports.

The Sierra rises sharply above the foothills. Snow cover and freezing can persist around higher trails while lower destinations are dry. Keep basin reports, foothill alternatives and road access separate when planning a ride.
Across the 7 networks Loam tracks here, elevation spans 6,598 feet and canopy runs from 0 to 62 percent. These measurements describe representative network points, not the full elevation range of every trail. Compare the individual forecasts and check local reports before choosing a ride.
The useful unit here is the riding zone. Each one has its own exposure, elevation, and weather response.
Start here for the current model at Loam's Tahoe/Truckee location. It cannot describe every elevation or shore of the lake. Use TAMBA's individual trail reports to plan a specific basin ride.
Auburn, Cronan Ranch and Folsom Lake are lower-elevation destinations west of Tahoe. They are alternatives on a regional trip, not parts of the Tahoe trail network.
Deer Creek is a separate foothill riding area near Nevada City. Check its own weather and conditions rather than carrying a Tahoe forecast west.
Sly Park is near Pollock Pines along the Highway 50 approach to Tahoe. Its forested setting and lake-side trails need their own conditions check.
Red Hills is well south of Tahoe near Chinese Camp. It is included as a farther foothill alternative, with its own trip planning and seasonal conditions.
Planning patterns, not opening dates. Live conditions and official access decide the day.
Snowmelt can keep high terrain inaccessible while lower foothill rides become possible. Check trail-specific reports instead of using a calendar opening date.
Higher trails become options as snow clears. Check smoke, fire restrictions and individual trail access before committing to a route.
Shorter days and freezing nights can change a riding window quickly. Higher terrain may receive snow before the foothills.
Do not infer snow-free trails from a dry model reading. Check snow coverage, winter road access and local restrictions; compare foothill destinations separately.
TAMBA publishes Tahoe trail reports with Trailforks. The Tahoe Rim Trail has sections where bicycles are prohibited and others with day restrictions. A regional model is not a snow survey or an access permit.

Rideable options around Tahoe & Truckee include Deer Creek Trail System (PRIME, firm, rideable conditions), Folsom Lake (PRIME, firm, rideable conditions) and Lake Tahoe / Truckee Area (PRIME, firm, rideable conditions).
This regional conditions page cannot establish that every trail is snow free. Check TAMBA and Tahoe Rim Trail reports for the route and elevation you intend to ride. The Tahoe/Truckee model represents one location.
The map includes Auburn, Folsom, Cronan Ranch and other separate foothill destinations. Compare their own conditions and official access; lower elevation is not a guarantee of dry or open trails.
No. Bicycles are prohibited on some sections, including wilderness and Pacific Crest Trail segments. Check the Tahoe Rim Trail Association's current rules for your exact route.
Loam updates condition estimates hourly. Each network page shows when its estimate was last updated.
Loam uses recent rain, soil, slope, slope direction, tree cover, and current weather to estimate how wet the ground is. These are estimates, not rider reports. Official closures take priority. See how the model works.
