Like the names suggest, the 2 billion-year-old rock formations of the Nevada desert are ones you won’t forget; on the other hand, the man-made might of Hoover Dam is also a highly memorable experience.

Another version of the tour includes river rafting that starts out at the Dam, continues 11 miles down the Colorado River and into the Black Canyon. Keep your eyes open for the Big Horn Sheep grazing along the shoreline, ancient Indian petroglyphs on canyon walls, and bubbling natural hot springs. Some of Rebel’s other very physical adventures you’ll like: the Custom ATV/Sandrails/Horseback Tour, where you reach locations out in the Mojave accessible only by ATV, and get to spot more snakes, lizards, wild Spanish Mustangs, Big Horns, and more awesome rock formations.

Challenge yourself on the fat tires with the Mountain Bike Adventure Tour (they can customize it to meet your level of ability) and bike up the mountainous terrain outside the city to take in the breathtaking view of the neon lights some 6,000 feet below you in the distance.

For a wetter and faster ride, their Jet Ski Adventure gets you out on Lake Mead, a brief instruction lesson, and into a 95 HP personal watercraft that will see you skimming across the clear waters of the Lake and another opportunity to view towering cliffs, hidden coves, and after you get back to the marina, enjoy the prepared lunch by the pristine beauty of the lake. In fact, all these adventures just need you to put your hands on the stirrups or wheel once you get there—Rebel picks you up and delivers you, provides all equipment and foods, water and instruction where needed. They last about 6 hours on average, which leaves you plenty of time to get back to your resort,
