Are You Ready to Hike? Safety is Your Responsibility

A few suggestions to help you stay safe:

 *Bring water and extra food

 *Wear sturdy boots

 *Bring a flashlight or headlamp

  *Use sunscreen 

  *Carry extra layers for warmth

  *Take breaks often 

  *Tell someone where you are going and when you will return

   *Check the weather forecast on-line or at the visitor centers

    *Finish your hike before dark

How Do I Safely Explore a Hydrothermal Area?

To help improve your level of safety, it is extremely important to stay on boardwalks and established trails in hydrothermal areas. One unfortunate visitor learned this lesson the hard way when he wandered beyond the barriers and safety warning signs. His foot broke through a thin crust hiding acidic boiling water and was severely burned. His injury required an emergency evacuation and a series of follow-up treatments and doctor visits.

In Case of Emergency, Dial 911

The closest emergency phone is at the Kohm Yah-mah-nee Visitor Center.

Pets Are Not Permitted on Hiking Trails

For the protection of wildlife and the safety of your pet, pets are allowed only in paved areas such as campgrounds and the park road.

Other information - Please be mindful of others on the hike.  Stay with the group, preferably those you car pooled with.  If you need to leave the group let someone know why, where you are going and when you expect to return.

    Just came back from camping at Lassen and Bumpass Hell was closed due to a lot of snow, I do not remember when it will be open. This will be fun :)
