The Greenstone Ridge Trail offers a challenging yet rewarding hiking experience as you weave through the rugged terrain of Isle Royale National Park. Spanning approximately 40 miles, the trail follows the island’s spine, giving you stunning panoramic views of dense forests, tranquil lakes, and remote wilderness. You will encounter diverse landscapes, from lush woodlands to rocky ridges, with several steep ascents and descents that require a good level of fitness and experience. Known for its solitude, the trail allows you to immerse yourself in nature without the distraction of large crowds.
Due to the island’s remote location, you will need to plan ahead, as the trail is best suited for those familiar with off-grid conditions and prepared for unpredictable weather. The trail is only accessible during the warmer months, from April to November, and you can reach it by ferry, water taxi, or seaplane from the mainland. Along the way, you will find a series of backcountry campsites, offering opportunities for multi-day treks and a deeper exploration of this pristine environment. The Greenstone Ridge Trail is a true adventure for those looking to disconnect and experience one of the most isolated and untouched natural settings in the United States.
