Guide to Trail Reports

All Clear — Trail is riding well right now and there are no reports of mud, deadfall, or snow.

Excellent — AKA Hero Dirt. Yes, your ideal conditions that you want to hit up first before any of your friends find out. Sure you want to keep it low key, but be a good trail steward and let your buddies know its time to shred.

Muddy Spots — Clear trails for the most part, but may run into occasional puddles or stretches of muddy areas. It is encouraged to go through puddles, and not around them. Also to turn back on long muddy stretches that damage or widen trails.

Dry/Dusty — Trail is good to go, but expect dry, dusty and loose trail surface and/or occasionally deep sandy areas.

Muddy — Please don’t ride muddy trails. This makes a LOT more work for folks who would rather be building new trails, than fixing your ruts.

Deadfall — This trail has lots of down trees. Riding it will probably mean getting off and climbing over and through tree limbs

Ice — Trail bed has extensive ice coverage. Expect very slick conditions.

Deep Snow — Trail bed is covered deep snow. Snow is unpacked and not rideable.

Packed Snow — Snow is mostly packed down from use and is rideable on a fat bike. Be mindful of icy spots.

Snow Patches — Trail is mostly dry but has a few snow patches here and there. Ride or walk though any snow patches — don't widen the trail by going around them.

Closed — This trail is closed right now. Details of the closure can be found in the trail description.

No Report — The current condition of this trail is unknown, if you’ve ridden it recently, please submit a trail report.

Unavoidable obstacles could be 8" or more and these trails often include avoidable obstacles which are larger. There will be occasional exposure or drop offs on areas of these trails.

Show Some Trail Love

Please observe the following suggestions when riding anywhere in the Boise foothills. There are a few special circumstances unique to Boise that visitors need to be aware of.

Skidding Causes Erosion
Soils here can be very dry in the summer and are easily eroded by excessive skidding. We try to design and build trails with this in mind but mountain bikers should ride so that skidding and hard braking are minimized. Control your speed. Please also AVOID trails that are wet during the spring melting season.

Keep Single Track Single
Most vegetation is fragile and very sensitive to trampling. When passing others stop your bike and put a foot down rather than ride around. This will avoid widening the trail unnecessarily. Use passing lanes whenever possible. When you stop for a break please remove your bike from the trail so others can pass without being forced to go off the tread of the trail.

Some Trails Might Be Crowded
Runners, dog walkers, families, tour groups, racers and recreational cyclists all share the same trails. Please be courteous to other users, and extend a friendly nod or “hello” when passing. You are not any more entitled to use these trails than anyone else; please behave and be friendly regardless of what the other trail users are doing.

Don’t Dumb Down Trails
If you encounter something which you are unable to clean, dismount and walk over the obstacle. Do not go around the feature or start a new line. Do not think that you are “doing somebody a favor” by “fixing” or otherwise removing a technical obstacle.

In addition to the above local guidelines please know and obey the IMBA “Rules of the Trail”:
