Mono 4th line 1.4km north of mono 5th sdrd. Road side parking for 3-4 cars. Take the Peter Beechum side Trail (25m) to the main Trail. Turn left. When you reach the fork in the Trail go right(ravine sd trait). Continue on to the next fork. Go right again and this will take you back to where you started. This route is short but hilly. This is one of my favourite routes, specially if I'm short on time .
