Feasibility of Walking Across the United States
The concept of walking across the United States is an ambitious feat that has been attempted by many. However, it is important to note that Hawaii is not included in this endeavor. There have been successful attempts by individuals who have walked or biked across the contiguous 48 states, and some have even ventured into Western Canada to reach Alaska, a journey that could face significant weather challenges.
Long-Distance Trails in North America
The United States is home to numerous long-distance trails that run up and down the major mountain ranges, from South to North, including the Appalachian Trail (AT), Pacific Crest Trail (PCT), and Continental Divide Trail (CDT). These trails are ideal for wilderness backpacking and require travel on foot or horseback with camping most nights. These are designated wilderness areas that may require additional safety measures to protect food from bears.
For those interested in a coast-to-coast journey through the United States, there is the American Discover Trail (ADT), which involves a significant amount of road-walking from Baltimore to San Francisco. This trail has been around for 20 years, and it is likely that there are numerous places to pitch a tent along the way. It's worth noting that the trail also covers a significant portion of Mid America.
Trans Canada Trail
Canada, on the other hand, has recently completed the Trans Canada Trail, now known as The Great Trail. While much of the trail is multipurpose and allows for both walking and biking, there are still 32 miles of road-walking sections. This trail stretches across the length of Canada and is an impressive feat in itself. Nevertheless, it's important to note that there are no comparable long-distance trails in Latin America, as there is no trekking and camping culture. However, the Patagonia region of Chile and/or Argentina is experiencing new developments with the creation of new protections and trails.
Historically, many 19th-century individuals made the entire crossing on foot, and more recently, every few years, modern-day adventurers have successfully completed this journey. To prepare for such an expedition, it is essential to carry enough food, water, and a variety of clothing along with a tent or sleeping gear. Long stretches of the desert portion of the American West are devoid of water supplies, thus making the use of a handcart with supplies more practical than carrying everything on one's back. Draw inspiration from the Mormon handcart pioneers who used this method to traverse difficult terrains.
Lastly, it is crucial to plan ahead and secure advice from someone who has already completed such a walk. Arrange for suitable camping locations where motels and hotels are either not accessible or are too far away to reach within one day's walking distance. Proper preparation and strategic planning are key to a successful journey.
