Depending on the trip and season dictates what to bring and we always recommend checking the weather prior to your trip!
During the winter months and our ski shuttle program wear warm winter, waterproof clothing. During spring, summer and fall if you are taking a tour out of Portland, wear comfortable shoes, appropriate clothing for season, often a sweat shirt or rain jacket and always bring a camera!
Other than that, bring a smile and a good attitude… lets go have some fun!
