Knolls Loop 9.9 mi

The closest multi-use trail to downtown Mammoth, this moderate, locals'-favorite loop is best accessed from the Shady Rest Path at the edge of Old Shady Rest Campground. In either direction, the trail alternates between singletrack, sandy OHV trails and dirt fire roads, climbing through old-growth Jeffrey pine forest into hills and domes formed by volcanic eruptions as recently as 100,000 years ago and affording broad views to the Inyo Craters and back across to the Sherwins. Look for basalt outcroppings and black obsidian once prized for making spear and arrow points. Avoid the heat of the day.
