The Missing Link Trail in Lava Beds National Monument plays a vital role, connecting the Three Sisters Trail to the Bunchgrass Trail, allowing you to embark on an exciting 10-mile (16 km) loop adventure. Accessing this trail is a breeze—simply follow the Bunchgrass Trail for about 0.5 miles (0.8 km) from the B-loop of the campground. As you explore, this trail will guide you across the street from the Symbol Bridge pullout, adjacent to Skull Cave road. From this point, hike 0.1 miles (0.16 km) east towards the Skull Cave parking lot, where you can seamlessly continue your journey along the Lyons/Three Sisters Trail to complete the captivating loop.
