What permits do I need for my trip?

1. Wilderness Visitor Permit: This is a free permit that helps us manage the number of visitors, have a record of visitors for safety in case of fire or other emergency, and preserve the nature of the wilderness. Help us in these efforts by picking up a free permit at the self service kiosk outside of the Forest Service Ranger Station in Idyllwild or request a permit in advance (allow 1 week notice). 

Please have a copy of your permit on your person during your visit to the San Jacinto Wilderness. If your party splits up during your visit each person should have a copy of your permit.  USFS permits are issued for groups up to 12 people. A separate permit is needed for each trip.  You may be asked by a U.S. Forest Service representative to see your permit while traveling in the wilderness.   

For more information, read "Why do I need a Wilderness Visitor Permit?"

NOTE: In order to prevent excessive impact on wildlife and wilderness resources, Devil's Slide Trail has a limit on the number of weekend permits issued during the peak summer season from the Saturday of Memorial Day weekend through Labor Day weekend.

2. Adventure Pass: If you will be parking at Humber Park, Lake Hemet, Lake Fulmor or Fuller Mill Creek, you will need to pick up an Adventure Pass for your vehicle. You can either buy a day pass at the Forest Service Ranger Station in downtown Idyllwild for $5, or a year pass for $30 with a second car included for only an additional $5.

Safety Tips

Don't forget your 10 essentials!
You should always be fully prepared for your trip with the 10 essentials of hiking and backpacking

When you head out on a hike, it's best to be prepared with the proper information and important essentials for your trip.

Please remember to bring enough water and clothing. You are responsible for your own well-being.

Please bring a filter if you plan on drinking from any body of water in the wilderness. Keep in mind that due to drought conditions there is a severe shortage of water sources in the high country. Plan accordingly.
