The first destination many follow is to simply hike to the saddle. From the saddle you can see the valleys on the north side of the range and on the south. There is a large open area for picnicking or just relaxing. From here there are trails heading in three directions that will take a little more time and will reach the summits of some of the more well-known peaks in this area. The hike to the saddle is easy enough to follow. Trail markers point the way to the old route or the newer trail. The hike more-or-less follows the river (or creek, rather, depending on time of year and rainfall) up to the saddle. It is a well-traveled and well-maintained path with many places to stop along the way and enjoy the surroundings.
Henninger Flats is a small hanging basin 2600 ft above sea level in the San Gabriel Mountains in the Angeles National Forest. It was part of the Mount Wilson Toll Road. The trailhead to reach the flats is at the top end of Eaton Canyon in Altadena.
