Want to make your Vegas trip truly memorable? Then join us on a tour of the funky, funny and fascinating.

1. Minus 5 Degrees Ice Lounge

This is literally the coolest spot in Las Vegas. Admission is steep ($30 includes a cocktail), but it’s an experience like no other. You’re issued a parka, gloves and hat, which you’ll need because the walls, seats and bar are made of ice. Room temperature is -5 degrees Celsius, or 23 degrees Fahrenheit. For comfort and safety, each visit is limited to 30 minutes. After the initial beverage, drinks are $10 each, with a limit of three. Then go warm up in Minus 5 Lodge nearby, a rustic tavern with an Arctic explorer theme. Location: Mandalay Place, 3930 Las Vegas Blvd. S., 702.632.7714.; www.minus5experience.com

2. Liberace Museum

Founded in 1979 by Mr. Showmanship himself, this over-the-top museum consists of two buildings: One houses the car and piano collections; the other has Liberace’s outrageous costumes, expensive jewelry, awards and even a replica of his bedroom. From his rhinestone roadster to his favorite grand piano covered in mirror tiles, this feast for the eyes is an unforgettable experience. The nonprofit museum supports the Liberace Foundation for the Performing and Creative Arts, which has given more than $5 million in scholarships to 2,200 students to date. Open seven days a week; admission is $15 adults. Location: 1775 E. Tropicana Ave., 702.798.5595; www.liberace.org

3. Haunted Vegas Tours

Elvis may not have left the building after all. As this three-hour tour unfolds, you’ll see the haunts of famous ghosts such as singer Presley (Hilton Hotel), gangster Bugsy Siegel (The Flamingo), and musician Liberace and comedian Redd Foxx (in their former homes) — to name a few. Led by a “mortician,” the fun begins at 9:30 p.m. and includes a stop at a haunted park, and a séance. General admission is $66.25. Location: Tour starts at Greek Isles Hotel & Casino, 305 Convention Center Dr.; 702.987.2222; www.hauntedvegastours.com

4. Lion Habitat

Here, Kitty, Kitty! This three-story-tall glass enclosure in the middle of the MGM Grand casino has real lions on display — at no charge to viewers. The felines are rotated in from the ranch where they live, so sometimes there will be lionesses and cubs; other times, it’s a big male strutting his stuff. The best time to visit is when the trainers are feeding them — you can get some great photos. For another view of the animals, stroll down the glass tunnel, which goes right through the habitat. Location: 3799 Las Vegas Blvd. S., 702.891.7777; www.mgmgrand.com

5. The Manilow Store

This is sheer heaven for a Barry Manilow fan, or those who want to impress one. Here you’ll find all things Manilow — CDs, DVDs, sheet music, clothes, jewelry and bobbleheads. Not only that, but you can record your own vocals to favorite Manilow music in the store’s recording booth. You can’t miss this shop in the Hilton: Look for the giant “Copacabana” sign suspended over the piano that serves as the desk. Open daily, 10 a.m.-11 p.m. Note: The singer currently is performing at the Hilton in a new show, “Ultimate Manilow: The Hits.” Location: Las Vegas Hilton, 3000 Paradise Rd., 702.732.5755; www.lvhilton.com

6. Vegas Mob Tours

Delve into Sin City’s sordid past on a tour that has even the locals raving. This two-hour bus excursion visits sites where mobsters were once active, and murders and disappearances commonplace. A “gangster” guide provides a fascinating narrative, exposing the secrets of mob boss Sam “Momo” Giancana, Tony “The Ant” Spilotro, Benjamin “Bugsy” Siegel and more. General admission is $56.25; show begins at 6 p.m. nightly. Location: Tour starts at Royal Vacation Suites, 99 Convention Center Dr., 866.218.4935; www.vegasmobtour.com/html/about.htm

7. Erotic Heritage Museum

Smirk if you must, but this museum aims to not only entertain, but also educate. Open just over a year, it claims to have “the largest erotic art collection in the world.” EHM seeks to bridge the gap between the commercial (pornography) and the aesthetic (folk, pop and fine art) through art, film, memorabilia and events. There’s a special emphasis on the history of the American sexual revolution in the 20th century. General admission is $15; open daily, 11 a.m.; must be 18 or older. Location: 3275 Industrial Rd.; 702.369.6442; www.eroticheritage.org

8. Red Square

This plush Russian eatery is open for dinner only (reservations recommended), but it’s the bar that blows people away. Voted the “Best Bar in America” by Playboy, Red Square boasts a subzero vodka vault and an “ice bar” offering more than 200 frozen drinks. Night owls will be happy to learn there’s a Reverse Happy Hour Sunday-Wednesday, 11 p.m. to closing, when  it’s half-price for specialty drinks, vodka-of-the-month cocktails and the bar menu. Cavi Hour is Monday-Friday, 4-6 p.m., and 1 ounce of caviar comes with two Imperia vodka cocktails per person. Location: Mandalay Bay Hotel & Casino, 3950 Las Vegas Blvd. S., 702.632.7407; www.mandalaybay.com

9. Atomic Testing Museum

Some have called this “the most interesting and enlightening museum in the city.” The focus is on the controversial Nevada Test Site, the nation’s main on-continent nuclear weapons testing facility from 1951 to 1992. Try the motion-simulator to get a feel for what it was like to observe one of the several hundred nuclear tests conducted over four decades. The story of our nuclear weapons development in the Nevada desert unfolds chronologically through a series of rooms, and some of the exhibits are downright scary. Location: 755 E. Flamingo Rd., 702.794.5161; www.atomictestingmuseum.org

10. Bodies ... The Exhibit

This touring exhibit now is in Vegas and is a must-see, if you aren’t squeamish. It showcases real human bodies and organs — 13 whole-body specimens and more than 260 organs and partial bodies. You’ll get a close look inside skeletal, muscular, respiratory and circulatory systems — and a wake-up call if you have bad habits such as overeating or smoking. Exhibit producers assure that the bodies are “respectfully presented.” General admission is $31; open 10 a.m.-10 p.m. Location: Luxor Las Vegas, 3900 Las Vegas Blvd. S., 702.262.4400 or 800.557.7428; www.luxor.com/attractions
