The Sulphur Skyline Trail in is a popular spot for hikers, snowshoers, and runners looking for a challenging adventure. The 4.9-mile out-and-back trail offers stunning views once you reach the summit, with expansive 360-degree panoramas of the surrounding valleys and mountains. The trail starts with a steady uphill climb through the forest, leading to a more intense ascent with switchbacks before reaching the treeline (the elevation gain is 2.15ft). The final push to the summit can be tough, but the breathtaking views make it all worth it. Don't forget to check out the nearby hot springs to relax after your hike!
