This is a review of the primitive (dispersed) campsites along the San Gabriel River Trail.
Upon entering one of the access points, park your car for free near the trailhead. It is good to advise one of the park attendants that you will be hiking or place a note inside your car that you are hiking.
The trail circles Lake Georgetown and is 26.2 miles. It passes through forests, grasslands, over some small hills and across a few tributaries.
This is prmitive (dispersed) camping. There are no facilities or amenities are these camp areas. Pack in some water and bring a water filter to obtain more. Leave No Trace principals should be practiced.
There are a few areas with tent pads or clear areas where you may camp. But there are also zones where you may simply camp wherever you can setup a tent or hammock. I'd say that 40% of the trail has some tree coverage, but 60% is exposed.
In the summer be aware that the combination of the temperature and the exposure can make this trail uncomfortable to hike. Take precautions, drink lots of water and stay in the shade all that you can. While you may be hiking within site of Lake Georgetown and the water, it is not always convenient to access the water. So be sure to carry plenty of water - at least 2 liters.
The trail is getting more and more popular with backpackers, so it is likely that you may see others on the trail. On weekends you may encounter scout troops practicing backpacking. During the weekdays you may not see a single person.
Dogs are allowed on the trail, but it is nice to keep them on lease.
