Mountain High Resort is committed to the safety and comfort of its guests. For this reason, we would like to offer a few suggestions to help make the most of your trip.


Mountain High Resort is located at 6,600 feet above sea level and rises to 8,200 feet at the summit. In rare cases, guests may experience symptoms of Altitude Sickness such as headaches, nausea, fatigue and shortness of breath. Most are minor and disappear immediately upon descent, however they can become serious if ignored. To minimize the effects of Altitude Sickness, if not completely prevent them, please follow these simple guidelines:

  • Exercise in moderation the first few days.
  • Drink more water than usual.
  • Reduce alcohol intake, which has a greater effect at altitude.
  • Eat food high in carbohydrates: grains, pasta, fruits and vegetables.
  • Avoid salty foods.


Staying warm and comfortable on the slopes is easy. The best choice is water-resistant, layered clothing that can be added or removed as conditions changes. It is always best to be prepared as the weather can and does change rapidly in the mountains. If your clothes are not water resistant, a water repellent spray can be applied.

Ultraviolet Rays

Ultraviolet rays are more powerful at elevation. Regardless of skin color or complexion, everyone needs to wear protective sunscreen and UV-certified sunglasses even on overcast days since ultraviolet rays can penetrate the cloud cover.

Your Responsibility Code*

Whether you are skiing or snowboarding, safety is everyone's responsibility. As a user of the Angeles National Forest, it is your responsibility to know the proper rules and etiquette of the mountain. For your enjoyment and the enjoyment of others, please be courteous to those around you and help promote the Responsibility Code whenever possible.
