This trail is tough. If you ride from Green River Cove trail north towards the parking area at Big Hungry Road, you face an uphill battle all the way. The trail starts with a hike-a-bike section up a steep slope of washed-out water bars, which alone is difficult to hike up.
Once above that section, there are a few rocky sections to climb over as well. The trail then levels off a bit until you reach the intersection with Rock Hop trail. Once past this point, the trail continues up severely washed out in some places with large water bar drops and loose rocks. You almost need to be a trials rider to hop up the top section of trail to the parking area at the top.
