Good job Kevin.
Just to add a few more things...
As I recall, there's at least one or two creek crossings between the trailhead and Bear Creek. The river crossings are typically in the shin to just-over knee deep range if there hasn't been a lot of recent rain. It's usually so hot and dry out there though that I just walk right through and my shoes dry pretty quickly on the other side. The bottom of the river is all cobbles and boulders, so barefoot crossings are no fun.
The trail itself is an old dirt road for most of the way, now closed to all wheeled vehicles as part of the wilderness designation. If folks come in at different times, it will be no problem for them to follow it on their own. It's well maintained and heavily traveled by LPNF standards.
The Bear Creek Campground isn't signed but there's a couple of fire rings in an area of a sandy clearing. The trail goes right through it. It's about 4.3 miles in from the Piedra Blanca parking lot/trailhead, right at the confluence of Bear Canyon.
If folks want to get a map of the area, Tom Harrison Maps has a good map of the Sespe Wilderness.
Almost the entire Sespe area burned in the 2006 Day Fire. The area is coming back nicely but be prepared for vistas dominated by evidence of fire. The riparian corridor along the river will be green and lush though.
One positive outcome of all of our recent fires... firewood is in great abundance all through the LPNF! No need to carry that stuff in, just collect in camp.
The Piedra Blanca/Lions Trailhead is a significantly shorter walk compared to leaving from Reyes Creek area. It's worth the $5 parking fee. The trailhead has lots of parking and restrooms. Maybe water too... can't remember, but if not, the first river crossing is almost right after leaving the parking lot. To get to the trailhead, turn off of Hwy 33 onto Rose Valley Road. Follow the main road until it ends at the trailhead parking lot, probably about 6 miles in.
If folks have extra time, the rock formations just north of the parking lot that give the area its name (Piedras Blancas) is worth taking a couple of hours to go explore. They're HUGE sandstone monoliths with lots of caves, crags, etc. Very cool! There's a few spots with evidence of Native American habitation in the area.
Adventure Passes can be had at certain sporting good stores in the area as well. You'll have to check the LPNF website, but they usually sell the passes at places like Sport Chalet, Big 5 Sporting Goods, etc. These places might be easier to get to than the LPNF offices or ranger stations which keep odd hours. Also, if folks already have an annual adventure pass (required for the LPNF along with the Angeles, San Bernadino, and Cleveland National Forests), they can buy a second annual pass for $5. Also, if folks already have the annual inter agency pass (for the National Parks, etc.), I believe that will cover you for parking in the LPNF as well.
Late April/early May is a nice time out there. Plenty of water still, probably some wildflowers hanging on and the weather is warm enough for a swim!
