I've hike this area with my dog a few times(on leash) and there are a few side trails you can take to make it longer if you would like. This area is full of ticks so be sure to check yourself and your dog after. If you do this hike and take one of the side trails to end up on East Laurel Creek Rd the best option is to turn around and go the way you came. Many times people walk E. Laurel Creek Rd or San Juan expecting to "loop around" but it will actually take you an additional 5 -10 miles to get back where you started if you go this way.
