Arroyo Seco: Arroyo Seco Trail (Gabrielino National Recreation Trail) is a 14.3 mile lightly trafficked point-to-point trail located near Mt Wilson, California and is rated as difficult. The trail is primarily used for hiking and is accessible from October until May. Dogs are also able to use this trail.
Hot! Not as described in Randall's 60 hikes within 60 miles as shady. Quite boring with several unseemly characters at Mesa campground and beyond. Would not go back to this section. The upper section coming down toward Switzer's is nicer.
Came here in late 2013 from the top-side. At the junction where the Bear Creek trail drops down into the ravine, this trail was marked as CLOSED. I missed the junction and after about 1 1/2 mile in Bear Creek, realized I was going the wrong way. The section I did hike was good, if a little crowded.
2/31/2014: Started on 2N69 next to the Edison Electrical Plant and headed to Gould Mesa CG. Came across several down trees blocking the road (high winds the night before). From Gould Mesa I headed north toward Paul Little. At Paul Little the trail is difficult to pick up (go right at the Paul Little sign). Trail is in poor shape as you gain elevation (there are two switchback that have been damaged by a landslide). Trail continues north around the Dam and by several sections of chain link fence which are falling onto the trail. You will eventually reach a drainage area where the trail has been eroded away (over a 10 foot drop). From hear you will slowly drop down into the riverbed (at this point the trail disappears). Follow the riverbed heading north & northeast until you reach Oakwide CG (nothing identifiable). From this point there is no clear route to Switzers but some bush whacking can get you there.
Took the trail from JPL today heading for Oakwilde. NFS website says camp is closed but did not indicate the reason. Once past Paul Little picnic area the route is difficult to find. We ended up on a game trail for about 100 yards and then caught the actual trail (or what's left of it) and went around the dam. Once there, the trail is gone, with the route sparsely marked with orange ribbon. Followed the riverbed to the coordinates of the camp, but nothing identifiable. We could not see a clear route from there to Switzers but some bush whacking can get you there.
