there's also another two in that area
one called CC mountain trail in the same area as twin sisters
and there was one other one but i forget the name.....
used to live in kettle falls for 7 years and had a relly good time 4x4ing and atving in the area....most of the 4x4 trails are up deadman creek road..which is across the hwy 20 bridge/lake roosevelt then north up 395 about 5.5 miles its on the left...:awesomework: there is also lots of forest service rd's
if you go to chewalah and go up towards the 49 degrees north ski area then keep going on Flowery trail Rd. you'll end up coming out by lake Pend Oreille close to idaho...one of my favorite drives...:awesomework:
