Take a trip to the Needles District of Canyonlands National Park and explore the Colorado River Overlook Trail. You can bring your bike, as the trail has enough bedrock to make it enjoyable for mountain bikers, though you will have to push through some sandy stretches. As a reward, you'll be treated to views of Ekker and Elaterite Buttes in the Maze District, and the mesas of Islands-in-the-Sky District of Canyonlands on the way out; the Needles, Six Shooter Peaks, and Ute Mountain on the way back. When you reach the end of the trail, take a short hike out to the viewpoints to look down into the Colorado River and the deep and narrow Salt Creek. Be sure to stay on the washes or rock to protect the fragile soil crusts. Park your bike at the Needles District Visitor Center and return the way you came. Note: Do not take the left fork going northeast about three miles from the end of the trail, as it leads to a gate and heavily grazed range land on the other side, making the track nearly impassible.
