Philbrook Road in the Lassen National Forest is the trail to the High Lakes OHV area and Philbrook Campground. This dense forest trail is roughly 5,606 feet above sea level and splits off Humbug Road near Paradise, CA. With towering pines, this trail is easy to get mentally lost due to its tranquil and scenic beauty. As you near the trail's end, you will pass by a seasonal lake (Philbrook Reservoir) and Philbrook Campground, which PG&E. owns. If you continue past that, several private cabins are on the eastern side of the lake before the trail continues to other trails. All offroad vehicles can do this trail since this is a maintained dirt road.
