For some 2,100 miles, the Appalachian Trail passes through some of the most stunning scenery in the Eastern United States. Throughout its entire length – extending from Springer Mountain, Georgia to Mount Katahdin, Maine – the trail passes through one single building, a historic stone structure known as Mountain Crossings at Walasi-Yi.

Since it opened in 1937, Mountain Crossings has served more than 2,000 hikers per year on their way to the northernmost trail head in Maine. Besides offering $15 dollar per night accommodations in its hiker hostel, Mountain Crossings ships home gear, helps hikers lighten their packs, treats blistered feet and offers advice, assistance and gear to long distance travelers.Hikers who've done 30 miles can toss shoes into the giant tree at the inn.

Many hikers who pass through the building leave a memento of their travels. Those who've hiked at least 30 miles of the Appalachian Trail toss their hiking boots into the branches of the tree outside before moving on (hopefully with a new pair of shoes). Hikers who have managed to hike at least 500 miles of the trail can leave their shoes or worn packs inside – a sort of badge of honor to inspire future hikers.Hikers who've conquered 500 miles or more can hang their shoes or packs inside.
