Head to the hills on Avimor?s trails; volunteers have built new trails

Trails are like restaurants. We have lots of both in the Treasure Valley, but it?s always exciting to get more because your appetite varies.

New trails at Avimor off Idaho 55 north of Boise offer another way to explore the Foothills.

“Just about every week we see more mountain bikers out here,” said Marc Grubert, an Avimor resident who is vice president for the Southwest Idaho Mountain Bike Association.

The Avimor trails, open to riders and hikers, were created by a partnership between the subdivision and its residents, and the bike association.

The main trailhead is at the end of Avimor Drive, which is off Idaho 55 about 7.5 miles north of State Street.


The original routes for many trails in the Foothills were old Jeep roads and livestock trails that were developed into recreational trails and linked to create the current Ridge to Rivers trail system.

The Avimor trails are similar, but the volunteer trailbuilders with SWIMBA have taken the lead in developing them. They’ve mapped old roads and converted cow trails to actual trails, and then built links to create a network.

SWIMBA president and head trail builder Mike Edwards of Boise said there are about 90 miles of old roads, developed trails and livestock trails in the area that can eventually be part of the Avimor network.

The routes range from near Idaho 55 all the way to the forests high in the Foothills.

Some trail sections are familiar to bikers who’ve raced in the Coyote Classic mountain bike races. Volunteers have also created another 17 miles of trails.

“It’s really kicked in in the last year,” Grubert said.

Most of the current trail network is on Avimor property, but other sections are planned while SWIMBA awaits the green light to develop them on adjacent Bureau of Land Management parcels, which are interspersed among Avimor’s property.


Trailheads are being developed this summer, as are signs marking trail junctions.

In the meantime, hikers, bikers and equestrians can use the trails, which will actually help them.

New trail sections were built during spring, and it typically takes rain and snow to fully compact the soil and form the trail tread. Fortunately, feet and tires can accomplish nearly the same thing.

Trail users should be prepared to navigate the trails without signs at each intersection, which are scheduled to be installed by volunteers later this summer.

Mountain bikers should beware that there are sections of the trail that are not rideable. Also be careful heading into blind corners, not only because there might be other trail users, but also because there might be rocks or creek crossings that are difficult to ride.

Equestrians are not allowed on all trails because some are on slopes that will not support the weight of a horse and rider. Those trails are marked on the map, and signs are posted on the trails.

Avimor trails do not get as much traffic as other Foothills trails, and cellphone coverage is spotty in the area. That’s important to know because if there’s an accident, you might be on your own.

With summer heat arriving, it’s best to get on trails early in the day. Some of the streams could dry up, but most have some pockets of water throughout the year. If you’re hiking or riding with pets, bring extra water for them to be on the safe side.


It’s important to remember that all Foothills trails are a mix of public and private lands. Just because you’re on a developed trail doesn’t mean it’s public property.

You also might see cattle and wildlife on or near the trails, so don’t let pets chase them.

If there’s fresh, green evidence of cows in the area, remember you’re a guest on their terrain, not the other way around.


SWIMBA plans to continue developing the Avimor trails system, and it can use some help.

The group is looking for others to adopt trail sections and do basic maintenance that nearly anyone can perform.

That will free up the trail designers and builders to continue creating new trails in the system.

The group has been building and maintaining trails in the Foothills and nearby areas for nearly 20 years, which benefits all trail users, not just cyclists.

People can become SWIMBA members or donate to the group, which will provide more money for trail projects. Go to swimba.org to sign up or to get more details.
