For our winter tours (using sleds), we do have a weight restriction of 250 pounds per person. An in general, we do not recommend our tours for people who are pregnant, have serious back/hip/knee problems, or people with general mobility impairments. These are outdoor tours, conducted on uneven surfaces which can be challenging to walk on in both winter and summer. Winter dog mushing can be great fun, but it can also be challenging – especially for beginners. There is always some amount of risk when you are a passenger in a dog sled as well – even when being driven by experts like us. Trail and weather conditions change constantly. Deep snow, icy hard-pack, ruts and holes can all cause a person to lose control of their sled, causing it to tip over or crash into a tree or brush. Minor wipe-outs are typically cause for a good laugh, but participants must have the physically ability to stand up in deep snow and get themselves back on the sled. Summer tours are generally safer, but may still not be a good idea for people who are pregnant or have serious back/hip problems as our tour trail can be VERY bumpy. Please talk to your doctor before booking a tour with us. Special considerations for children: We do not have any age restrictions. Children five years old and younger must ride on the lap of an adult or older child while sitting in the dog sled. In most cases young children are still allowed to try driving the dog sled on the safest, easiest portion of the trail. Please keep in mind that our tours are designed to be educational, and the content we cover is sometimes too complex for children. We find that while all kids are thrilled with the dog mushing, a significant portion of our tour also involves standing around, petting dogs and answering adults’ questions about raising and training dogs, running 1,000 mile races, living off-grid in Alaska, etc. Not all children are mature / calm enough to act appropriately during these times of the tour. This can degrade the experience for the adults who are also present.
