Hike Across the Country on the American Discovery Trail

---

The American Discovery Trail is the ultimate journey across the United States. Spanning the entire width of the country, the path weaves through small towns, vast prairies, towering mountains and dense forests. This is what awaits you on the coast-to-coast adventure. However, this challenge is not for the faint of heart and extensive prep and planning is required to a successful journey. 

What is the American Discovery Trail?

The American Discovery Trail (ADT) is far from your average hike. It’s a unique and ambitious journey that stretches across the United States from coast to coast. The challenging trail spans over 6,800 miles, and it connects 15 states, taking you through some of the most diverse landscapes in the country. The ADT shows off everything the States has to offer, from mountains and forests to cities and farmlands — you’ll see it all on your trek. 

From Delaware to California, it’s the only coast-to-coast trail in the country, connecting both the Atlantic and Pacific Oceans. What makes the ADT special is its versatility. It’s designed with both hikers and cyclists in mind, with sections that can also be navigated on horseback. The trail doesn’t just pass through the middle of nowhere — you’ll see small towns and cities along the way, too. 

Hiking the ADT is a major undertaking that can take anywhere from eight months to over a year, depending on your pace, the route you choose and how much time you spend exploring along the way. Most people who attempt to hike the whole trail do so in sections, spread out over several years. Others might dedicate an extended period to complete it in one go. Whether you’re interested in tackling the entire trail or just a section of it, the ADT is a must-do bucket list item if you love the great outdoors. 

Planning Your Big Adventure

The ADT takes a winding route across the U.S., beginning in Delaware and stretching all the way to California. Along the way, you’ll pass through 15 states, from the Appalachian Mountains to the Great Plains and the Rocky Mountains. The trail isn’t a straight line though. It meanders through national parks, forests and small towns, giving you a diverse experience of the country’s natural beauty and cultural landmarks. 

There are also alternative routes in some areas, allowing you to choose between different paths depending on what you want to see. For instance, you can take a northern route through Ohio or Indiana or a southern route through Kentucky and Illinois. This flexibility makes the trail accessible to different types of adventures, whether you’re looking for a challenging hike or a scenic bike ride.

Some of the most breathtaking sites you’ll spot along the way include:

• Rocky Mountains
• Great Plains 
• Appalachian Mountains 
• Sierra Nevada
• Ohio River
• Lake Tahoe

Essential Gear and Equipment

When tackling this route, having the right gear is crucial for a safe and enjoyable experience. Here’s a list of essential items you’ll need for your journey:

• Backpack: A sturdy, comfortable backpack with enough capacity to carry your gear, food and water. Look for one with adjustable straps and good weight distribution.
• Hiking boots: High-quality trail runners or hiking boots are essential. Make sure you break them in well before the time to avoid blisters.
• Navigation tools: A detailed map of the trail, a reliable GPS device and a compass are nonnegotiable. Don’t rely solely on your phone, as you might lose signal in remote areas.
• Shelter: A lightweight, durable tent or bivy sack for overnight camping. A good sleeping bag rated for the temperature you’ll encounter is also essential.
• Clothing: Layered clothing to accommodate changing weather conditions, including moisture-wicking base layers, an insulating mid-layer and a waterproof jacket or windbreaker. Don’t forget a hat and gloves for colder regions. 
• Food and cooking supplies: Non-perishable, lightweight foods like dehydrated meals, energy bars and nuts. A portable stove or a lightweight cooking system is helpful for preparing hot meals. 
• Water supply: You’ll need to carry enough water to last for long stretches between water sources. A hydration system or large water bottles are a great option. A water filter or purification tablets are also necessary for treating water from natural sources to avoid stomach problems and having to cut your trip short. Some areas are especially dry and water isn’t readily available, so it’s best to be prepared. 
• First aid kit: A comprehensive kit with bandages, antiseptic, pain relievers, blister care and any personal medications is crucial when encountering injuries and illness.
• Lighting: A headlamp or flashlight with extra batteries will come in handy when navigating low light or after dark.

What to Expect on the Trail

As you begin your journey, you’ll quickly realize the scale of the adventure. The ADT takes you through some of the most iconic landscapes in the country, including the Rockies and the Sierra Nevadas. Along the way, you’re sure to meet locals who offer a deeper understanding of the places you pass through. 

Shelters and campsites vary along the route — some sections offer well-maintained campgrounds or shelters, while you’ll need to rely on backcountry camping or local accommodations in other areas. It’s essential to research each segment before you start, ensuring you know where to find resupply points and places to rest. Some areas may have amenities close by, such as small towns or hostels, while others might be more remote, requiring careful planning for water and food. 

The best time to hike ADT largely depends on the section you’re tackling. Generally, spring and fall are ideal for most parts of the trail, as temperatures are moderate and conditions are more favorable. However, certain regions, like the deserts or high mountains, may have optimal windows outside these seasons.

The trail itself is free to hike, but you should be prepared for potential fees at campgrounds or parks, and consider budgeting for any local accommodations or services you might need along the way. You’ll usually be required to pay a fee and show permits when entering national parks and public lands. 

Coping With the Mental and Physical Challenges

Hiking the ADT requires immense mental and physical strength as the route will test your limits. Physically, you’ll confront long days on your feet, varied terrain and unpredictable weather. Blisters, muscle fatigue and joint pain are part of the package, but each step can feel like a struggle. To cope, focus on maintaining your gear and listening to your body. Regularly stretching, drinking plenty of water, eating enough and adjusting your pace can prevent injuries and manage discomfort. 

Mentally, the challenges can be even more daunting. Loneliness, moments of doubt and the sheer magnitude of the hike can weigh heavily on you. To stay resilient, build a strong support network before you start — connect with fellow hikers or a community who can offer encouragement and advice. Hiking with a group or close friends can make the experience more enjoyable and help you through those tough times. Embracing the solitude and using it as an opportunity for self-reflection can transform the mental hurdles into moments of personal growth and insight.
