Anyone carrying a satellite communicator or satellite-capable device should make sure it is fully charged, activated, and tested before the hike.

Please come prepared for a long day in the mountains:
• Light, moisture-wicking clothing layers. Avoid cotton.

Mt. San Gorgonio is a serious endurance hike. Preparation, hydration, pacing, nutrition, and teamwork will be essential. Our goal is not simply to reach the summit, but to have everyone complete the hike safely and enjoy one of Southern California's great mountain adventures.

See you on the trail!
