Middle Sam Merrill starts from the Mt Lowe Fire Road at the intersection to Inspiration Point. The single track trail is narrow, exposed and loose. It begins on the shady side of the mountain and wraps around to the sunny side where it gets increasingly loose and dry. This is an advanced trail with exposure, rock drops, etc.

Be aware this is a multi use trail and hikers are commonly found coming up from the Echo Mtn ruins below. Bell use is highly recommended and appreciated by other trail users. This trail commonly causes flats so be prepared with extra tubes, pump, etc. Also a good idea to check your brakes before riding this trail as you will be using them and using them heavily.

       This section is awesome. Nice amount of technical but can be ridden fast and flowy once you get the feel for it. Some tight rocky steep sections, small drops. Gets even better with some rain.
