22 LASSEN PEAK TRAIL SIGN. On the southeast side of the road is the Peak Parking Area, and on the northwest side starts the trail up Lassen Peak. The Peak Trail is a well-graded climb of about 2,000 feet: from 8,500 feet to 10,457 feet in 2½ miles of hiking. It takes most persons about 4 hours for the round trip, though some take an hour more, and a few an hour less. For a pleasant hike:

1. Wear low heeled, sturdy shoes. 2. Hike at a moderate pace, taking short, frequent rests and enjoy the ever-changing view. 3. Take a lunch along. 4. You can eat snow for water, but do so slowly, otherwise it may make you ill. 5. Dark glasses, sunburn lotion, and a hat are advisable. 6. Do not start later than 2 hours before sunset, or when storms or fog threaten. 7. DO NOT TAKE SHORT-CUTS ACROSS THE TRAIL. It is against Park Regulations and is inadvisable because: a. It is dangerous: sprained or broken ankles and arms may result. b. Unavoidable dislodging of rocks is dangerous to hikers below. c. It costs money to rebuild the trail which short-cutting ruins.
