Layered Clothing: Mountain weather changes rapidly. Even in August, temperatures can drop significantly at Cumbres Pass. Coaches are not heated, so please bring a jacket or windbreaker.
Sun Protection: The sun is much stronger at 10,000 feet. Bring sunscreen, sunglasses, and a brimmed hat or ball cap.
Insect Repellent: We recommend bug spray, as mosquitoes can occasionally join the ride during certain stretches of the route.
Sturdy, Closed-Toe Shoes: This is essential for your safety when moving between cars, walking in the rail yard, and stepping off the train onto uneven terrain at geologic outcroppings.
Eye Protection: If you plan to spend time in the Open-Air Gondola, eye protection is highly recommended to shield against coal cinders from the steam locomotive. Sunglasses or prescription glasses work well; safety glasses are also available for purchase in our gift shop.
