The Grand Canyon was carved over millions of years by a river that just couldn't get its smile quite right. Soak in the most labored-over sculpture in history with today's Groupon: for $79, you get a Grand Canyon Express West Rim Tour from Comedy on Deck Tours (a $160 value).

Following the lead of a veteran guide, the Grand Canyon Express West Rim Tour whisks its guests through memorable vistas and across the border splitting Nevada and Arizona on its way to the famous landmark. Each sightseer receives a light breakfast of a danish and juice, and a brief stop in Boulder City affords everyone on board the chance to stock up on additional victuals. Jaunts cross into Arizona over the Mike O'Callaghan – Pat Tillman Memorial Bridge, just 1,600 feet from the Hoover Dam and its adjoining beaver-art museum. The tour's Grand Canyon stop lingers for three hours and includes a visit to Indian Village, where a self-guided tour introduces guests to the lifestyle and rituals of the Hualapai tribe.

After Indian Village and Eagle Point, tours continue on to Guano Point, which affords a spectacular view of the canyon. Eagle Point derives its name from a noble bird-shaped rock formation at the spot, and tour takers can view the canyon from an avian perspective with an optional stroll across Skywalk, a glass bridge jutting out 4,000 feet above the canyon floor. Named for the product of the bat-filled mine at its base, Guano Point grants a 360-degree view of the area, earned after a hike up its hill, which remains free of fences, guardrails, and tsk-tsking grandmothers. After the Points, mini buses roll on for a stop at the shopping center and then back to Vegas between 4:30–5 p.m., leaving time in the day for other Vegas attractions.
