ATV riders . . . 

Refer to the map to find those 

roads and trails that are open to 

ATV travel. From snow melt to August 29, both 

trails between point  and point  are open 

to ATVs. 

The Kirkham Ridge Trail (#144) starting at the 

junction with the Miller Mountain Trail (#159) 

at point  is closed to ATVs, but open to 

motorcycles. ATVs are not permitted past the 

gate on this trail. This is a single-track trail 

that penetrates deep into the primitive Red 

Mountain Roadless Area and terminates at the 

trailhead near Bull Trout Lake. 

The Lick Creek Road (#558) and the Miller 

Mountain Road (#592) are open to all motor 

vehicles. ATV riders must have a current State 

driver’s license and an OHV registration sticker. 

All state laws pertaining to motor vehicle 

operation must be followed on these roads. 

Be EXTREMELY careful as there are numerous 

blind, narrow corners. 

The Lick Creek Road offers a loop route. 

You’ll see several scenic views and large rock 

outcrops. If you travel to 

Highway 21 on this road, 

watch for children in the 

residential area where 

the pavement begins.

Motorcycle

riders . . .

The Kirkham Ridge and Miller Mountain trails between point  and point 

are open to motorcycles from snowmelt in the 

spring until closed by snow in the winter. Be 

careful on the first few miles of the Miller 

Mountain Trail (#159) past the gate as a miner 

has access to a gold claim in the area. He 

drives a full size vehicle on the trail. 

If traveling far up the Kirkham Ridge Trail, 

be aware that there are two trails closed to 

motorized vehicles: Clear Creek (#145) and 

Cat Paw Lake (#142). Off-trail motorized 

travel is prohibited.

Stay on the traiL . . .

It is very important that motor vehicles stay 

on the designated trail. Even though there are 

numerous tempting opportunities to leave the 

trail and follow ridge lines or cut across switchbacks, you must stay on the trail. 

The main trails are well marked 

with signs. There are a few short 

spur trails to points of interest or 

scenic view points which are also 

marked with these signs. They 

are posted on the trail to let you 

know you’re on the right track.

These signs are posted where evidence of 

previous unlawful off-trail travel may confuse 

you. The red slash indicates that motorized 

travel is not allowed behind the sign.

Be responsible . . .

Irresponsible OHV riding has led to closures of 

trails. The decision to allow motorized use on 

this trail was made with the assumption that 

vehicles would stay on the trail and not damage 

the environment. Scarring the landscape and 

destroying the vegetation along the trail could 

result in closure and it will make other trail 

users critical of your right to share access into 

the forest. You can gain support of hikers and 

horseback riders and ensure your future use of 

this and other trails by staying on the trail.

If it’s green and living,

don’t run over it!
