Trails start at 40 minutes East on I90 or US2 highway. According to onX there are some challenging ones but I have only done forest roads during break-in period and while I’m getting to know vehicle.
Assuming you're referring to Redmond Oregon. The cascades surround us, so there are fire roads all over the place. Some areas can get pretty banged up and become a challenge due to snow melt. North of Redmond there's some neat fireroads around Lake Billy Chinook, to the west I really like the trails near santiam pass (look for cache mountain), and down south past Bend is the lava cast forest which has some cool roads.
