Greenstone Ridge Trail

The Greenstone Ridge Trail, a gem within Isle Royale National Park, offers a unique blend of natural beauty and solitude. Spanning approximately 64 kilometers (40 miles) and boasting an elevation gain of around 900 meters (2950 feet), this point-to-point trail traverses the spine of Isle Royale, providing hikers with a diverse array of landscapes and wildlife encounters.Getting to the Trailhead To embark on your journey along the Greenstone Ridge Trail, you'll need to reach Isle Royale, which is accessible only by boat or seaplane. The most common entry point is near Keweenaw County, Michigan, where you can catch a ferry from Houghton or Copper Harbor. Once on the island, Rock Harbor is the starting point for many hikers. From there, you can take a short water taxi ride or hike to the official trailhead at Windigo, located on the western end of the island.Navigating the Trail As you set out from Windigo, the trail will lead you through a mix of northern hardwood and boreal forests. The path is well-marked, but carrying a reliable navigation tool like HiiKER is advisable to track your progress and ensure you stay on course.Landmarks and Natural Features The Greenstone Ridge Trail is named after the greenstone (chlorastrolite) that is native to the area and occasionally found along the trail. The ridge offers panoramic views of the island and Lake Superior. One of the first significant landmarks you'll encounter is Mount Desor, the highest point on the trail at around 423 meters (1386 feet). It's roughly 37 kilometers (23 miles) from Windigo, making it a challenging but rewarding first or second day's hike.As you continue, you'll pass by numerous inland lakes, each with its own unique ecosystem. Siskiwit Lake, the largest on the island, is a notable landmark approximately halfway through the trail. It's a great spot for a rest or a refreshing swim on a warm day.Wildlife and Flora Isle Royale is famous for its moose and wolf populations, which have been studied extensively for their predator-prey dynamics. While the wolf population is elusive, you're likely to spot moose, especially in marshy areas. The island is also home to a variety of bird species, making it a birdwatcher's paradise.The trail is lined with wildflowers in the spring and summer, including thimbleberries, which are ripe for picking in late summer. In the fall, the foliage transforms into a vibrant display of oranges, reds, and yellows, offering a spectacular backdrop for your hike.Historical Significance Isle Royale has a rich history, with evidence of copper mining dating back to 4500-1000 BCE. Throughout the hike, you may come across remnants of the island's past, including abandoned mines and ancient pits left by indigenous miners.Preparation and Planning Given the trail's remote nature, it's essential to be well-prepared. There are few amenities on the island, so you'll need to pack in all your food and gear. Water is available from inland lakes and streams, but it should be treated before drinking.Camping is permitted only at designated campgrounds, and permits are required for overnight stays. It's recommended to reserve your campsite or shelter in advance, especially during peak season.Weather and Safety The weather on Isle Royale can be unpredictable, with sudden changes and cool temperatures, even in summer. Be sure to pack appropriate clothing and gear for rain and cooler weather. As always, leave no trace to preserve the wilderness for future hikers.By respecting the natural environment and preparing adequately for your journey, the Greenstone Ridge Trail promises an unforgettable hiking experience filled with stunning vistas, diverse wildlife, and a sense of tranquility that can only be found in this secluded corner of Michigan.
