Larison Rock begins in Greenwaters Park in the heart of Oakridge. Follow paved Larison Rock Road uphill for five-miles to FR 3607. Stay right onto FR 3607 and get ready to descend 3.4 miles through lush rainforest. Be prepared for tight switchbacks, patches of loose rocks and creek crossings. The twisting, mostly smooth trail ultimately leads you back to the parking lot at Greenwaters Park.
