PCT: Ca Section C I-10 at San Gorgonio Pass to I-15 Near Cajon Pass is a 127.5 mile lightly trafficked point-to-point trail located near White Water, CA and is rated as difficult. The trail is primarily used for hiking, camping, and horses and is accessible from April until October. Dogs and horses are also able to use this trail.
PCT crosses interstate 10 highway, the trail on the north side of the highway is worth hiking but the one on the south side in the summer, is not really that interesting, and it’s because the shrubs and majority of plants are brown (looking dead). May be in the winter season it’s okay to hike that flat noisy area because it’s next to the highway and the railroad which run parallel adjacent to the highway. If possible avoid this trail period.
There’s a portion of PCT on the same path if you go further south at Snowcreek Canyon Rd. where it intersects PCT, that’s an awesome trail that goes all the way up to Idyllwild, you’re better off exploring that area then the one next to the highway. You’ll regret if you didn’t,
If anybody really must see PCT south of I-10! Finding a parking is going to be tricky if you're not from Palm Springs. The best place to park is actually underneath I-10. You'll have to go to Tamarisk Rd. and where PCT crosses the Hwy there's a dirt road that goes underneath the highway, that’s the best location to park, because your vehicle will not be seen from Tamarisk or the Hwy. Probably the safest place to park!
