Head across the road and take to Long Ridge Trail back around to Grizzly Flat. There are many options. Some steep, some flat, but there are some great trails. Go park at the lot across the street. Trails is not all that hard and not much downhill.
Trails are singletrac and smooth as a baby's asscaca.
When you reach the road crossing midway up the trail, don't get hit. The trails above this section are not all exciting and mostly loose fireroads. Also, hardly any trees up there, all grassland. My friend and I turned back because the trails didn't see to be worth the climb. You can park somewhere near mount eden rd.
