Angeles National ForestFish Creek Canyon has a quarry at the mouth, making access difficult. The quarry has a few access days somewhat less than every other Saturday during which they provide parking and shuttles to go up the canyon. This makes the hike up to the falls about 2 miles. The shuttles used to allow people up until noon and continued running them back down to 3 PM, but recently this time has been shortened. There is also a route made to bypass the quarry to get into the canyon from just after the gate to the quarry which adds about 3 miles to the trek up to the falls and which no one seems to have anything good to say about. Previous years when I have gone, the part of the bypass trail coming down to the canyon looked wide and used. The first mile of the other side, which I have been on, looked used, but was overgrown once it got to the other side of the canyon wall. When I went this year (28 May 2011), the access trail down in the canyon was looking much less used and unmaintained. The quarry has now swapped some land east of the creek for land west of the creek and I'm not sure what this means for the access trail. Dan Simpson suggests that access can be arranged with the quarry, as well.
There are three ways to increase a hike in the canyon that I have not yet tried:
