The beginning of the climb on the Weldon Motorway may seem like a violation of your constitutional rights, but after a short initial stretch of steepness, the grade mellows out and this becomes an enjoyable hike that provides nice views of the San Fernando and Santa Clarita Valleys.

At about a mile and a half in, you can take a break and reward yourself with a rest at a viewpoint.  Here you get a dramatic aerial perspective on neighboring East Canyon.  You continue along the fire road – at this point having gained most of the elevation required for this hike.

Finally, at 2.5 miles, you arrive at a junction where a road heads left toward Mission Point and O’Melveny Park, and right down through East Canyon. In fact, instead of retracing your steps down the Weldon Motorway for a 5 mile round trip, you can descend through East Canyon and return along the Old Road, crossing the overpass and walking along Coltrane, for a total hike of 6.5 miles with 1,300 feet of elevation gain.
