A loop - halfway down Cardiac trail, south on oregon bar cross trail, uphill on Oregon bar trail and a bit on Eagle's nest road. Return on level path next to Shirland track canal. One of several loops that can be made near Oregon bar... One would be to go to the river on Cardiac and come up Oregon bar trail, either half way to the oregon bar cross trail used here or all the way up to Shirland track. Depends on how far you want to go. Much of the Oregon bar trail crosses a piece of land that Placer Land Trust has acquired a conservation easement on. Hopefully that means this area will be open to hikers for some time to come.
