Boxcar Rock is a spur off of Boxcar Cove that climbs to a higher viewpoint versus the cove road that drops directly down to the waterline. Even though this trail puts you high above the shore, shells of small freshwater clams litter the ground as evidence of how Lake Mead has shifted over the decades. Stone fire rings show the area's frequent use by dispersed campers; you'll find these along many of the access roads. The hardest part of Boxcar Rock is a soft sand climb that may require 4WD if ruts form or natural erosion wears at the trail. The view of Lake Mead from the rock cliffs at the end of Boxcar Rock is spectacular, and with a little exploring, there are great swimming spots to be found.
