Named for the twisted, spiky trees, there's so much more to see in this popular California national park with its rugged rock formations, breathtaking views, a wide variety of wildlife, and stark desert landscapes. As the audio guides play commentary based on your GPS location, you can create your own itinerary along the tour route to match your interests and schedule.

The 30-foot granite Arch Rock is an Instagrammable location in Joshua Tree National Park. Take a short hike to Arch Rock to see the natural arch within the granite formations surrounding White Tank Campground. Though it's spectacular at any time of day, try arriving around sunset for one of the park’s iconic photo-ops: a gorgeous thirty-foot span of granite beneath a pastel-hued sky. It’s a mere 1.4-mile out-and-back hike to the arch, but we recommend you tack on a second formation: Heart Rock. Although a bit lopsided, this formation really does resemble its name, and it's an understandably popular place to snap a photo with a loved one.

Barker Dam is a natural basin that was walled in 1902 to improve water storage for cattle ranchers - and it has fantastic scenery, short interpretative nature trails, and historical significance. The Barker Dam trail is a 1.3-mile nature loop, with some easy scrambling and interpretive panels. It passes the southern edge of the backcountry area known as the Wonderland of Rocks. It's not quite a true dam, it is actually a natural basin that was walled in in 1902 to improve water storage for cattle ranchers. Either way - it's quite a pretty sight.

The Cholla Cactus Garden is one of the most surreal sights in Joshua Tree National Park, with hundreds of furry-looking cacti, gleaming silver and gold in the day's fading light. You won’t want to miss the surreal sight of hundreds of teddy bear cacti gleaming softly in the sunlight. To be sure, while they may look fuzzy from a distance, these plants are most assuredly not related to teddy bears: their furry appearance comes from the thicket of spines that cover the stems. Beware - though they are pretty to look at, you really don't want to touch them, especially accidentally.

Hall of Horrors is Hall of Horrors is a popular location with several rock formations that can be explored on dirt paths and is a popular destination for scrambling and rock climbing. This area is also surrounded by mountains and provides many scenic views. The namesake hall is a fun photo op for those comfortable with a little rock scrambling and is reached by circling around the right side of the first formation you see. The narrow dark corridor, or hall, is hidden in the second formation back from the road, it does require some exploration and a sense of adventure to find - but it's worthwhile.

Hidden Valley Nature Trail is an easy one-mile loop through Hidden Valley on a dirt and rock trail. This is a popular hike through a rock-enclosed valley surrounded by unique rock formations. A one-mile loop guides visitors through this small valley encircled by giant buttresses and granite domes. It was isolated enough to be used as a hideout for the McHaney Gang, outlaws, and cattle rustlers who were active in the 1870s and '80s.

Keys View is a popular viewpoint perched on the crest of the Little San Bernardino Mountains, that provides panoramic views of the Coachella Valley. A ten-minute side-trip drive climbs up to an elevation of 5,185 feet, and it's the highest road in the park. From here you’ll have views of the entire Coachella Valley, from the San Andreas Fault and distant Salton Sea to Palm Springs and the snowcapped peaks of San Jacinto Peak and Mount San Gorgonio. A terrific view not to be missed.

Skull Rock is a popular stop in the park, to see a rock that looks like a huge skull. As more rock eroded, more water accumulated, leading to more erosion until, as time passed, two hollowed-out eye sockets formed and the rock began to resemble a skull. From different angles and when the sun is shining at different levels, the skull changes its appearance and mood.

Split Rock is a gigantic boulder that's been split in two with a good short hike to the rock and a lovely picnic area to stop at. Imagine the forces that caused the boulder to split!
