On this week’s agenda: an afternoon stroll through Springs Preserve’s gardens, kid-friendly walks with dinosaurs, an Australian version of the Bee Gees, and a night with Jay Leno. As always, check Groupon for even more great things to do in Las Vegas. Botanical Gardens Guided Walk at Springs Preserve Westside | Every Saturday and Sunday Every Saturday and Sunday at 11 a.m., 1 p.m., and 3 p.m., Springs Preserve’s expert staff leads guests through a guided walk of their botanical gardens—which include 110 acres of display gardens, natural gardens, and wildlife habitats. The gardens are also home to the biggest collection of Mojave Desert cacti and succulents. (333 S. Valley View Blvd.; free) Jay Leno at the Mirage The Strip | Friday, August 8, at 10 p.m. Late-night funnyman Jay Leno stops at the Mirage as part of the Aces of Comedy series, continuing a post-retirement return to his standup roots.

They’ll get to identify different dinosaur tracks and make their own footprints as part of the activity—and see which adult shrieks first when the 35-foot-long T. rex lowers its head and roars. (900 Las Vegas Blvd. N.; free with paid admission; buy tickets here) The Australian Bee Gees at Excalibur The Strip | Sundays–Thursdays at 7 p.m., Saturdays at 5 p.m. During 75-minute multimedia tribute shows, the Australian Bee Gees recreate the sounds, styles, and moves of rock and disco legends the Bee Gees. While they play hits like “How Deep is Your Love” and “Staying Alive,” audience members can groove along, recreating (or creating) their own disco moves. (3850 Las Vegas Blvd. S.; $44.95+; buy tickets here) Sin City Comedy and Burlesque at Planet Hollywood The Strip | Nightly at 7 p.m. and 8:30 p.m. Comedy and burlesque have been bedfellows since the days of vaudeville. These days, they come together at Planet Hollywood’s nightly show, Sin City Comedy. Founded by longtime standup comedian John Padon, Sin City Comedy features a rotating lineup of top comedians who have appeared on everything from Comedy Central to VH1 and the Late Show with David Letterman. As for the burlesque element, we can’t so much as offer a tease—but that’s the point of the show. (3667 Las Vegas Blvd. S.; $42+; buy tickets here)
