Important Reminders

Lowell is located at 7200′. You will want to pace yourself if you’re not accustomed to the high elevation. Avoid becoming dehydrated by drinking plenty of water. Dress in layers; evenings can be cold, even in the summer. In the daytime, wear sunscreen to protect against sunburn. Please note that while people walk their dogs in the nearby forest and several employees who live on Mars Hill own dogs, only service dogs are allowed in the areas of campus open to public visitation. Certain buildings and facilities may be closed for private events.

For general questions about our day and evening programs, call the Visitor Center at (928) 233-3212 during open hours (listed above).
