First, welcome to Wrangler forum. There is no legal trails in the Mt. Hood national forest. You are limited to logging roads which are great for snow wheeling in the winter. If you do find some old jeep trails there please stay off them, it makes a bad name for everyone. Keep it legal. Head over to Tillamook state forest in the coast range. There is trails for all types of vehicles from mild to wild. It's more commonly referred to as TSF. Get on youtube and search tsf wheelin. That will get you an idea of whats there. Also go to the Oregon forum here and there is runs all the time. I'm going 5/16 if you want to go. May 16th T.S.F. run
There is is sticky in Oregon forums that post meet and greets as well as runs. Come say hi.
