The World's Weirdest Tourist Attractions

You may have seen animal reserves before, but what about a home for garden gnomes? The Gnome Reserve in Devon, England, has more than 2,000 gnomes scattered free-range-style around Merry Harrier's Garden Centre. Visitors can pose for pictures with the statues, using the provided fishing rods and gnome hats to blend in. Dogs are welcome to visit, but they must be on leashes so they don't scare the gnomes.

Go underneath the beauty of Paris—deep into the city's bowels. The Sewer Museum (Le Musee des Egouts de Paris) offers a firsthand look into the sewage system of The City of Light. Educational exhibits are located atop grated walkways, through which you can see the drain water rushing along. You will be inside a working septic system, so don't expect it to smell like a Parisian patisserie down there.

Often called one of the germiest tourist sites in the world, the Market Theater Gum Wall has been collecting germs and chewed gum since 1993. Theatergoers waiting in line for the Market Theater's box office started sticking their gum on the wall here in Post Alley (some even getting creative and molding their discarded chews into sculptures). The collection has been removed and cleaned multiple times, but it keeps coming back.

Deep within a labyrinth of canals in Mexico lies possibly the world's creepiest island—Isla de las Munecas. To get to the "Island of the Dolls," you'll have to hire a trajinera (a special wooden boat that can navigate the canals) for a two-hour trip. At the island, you'll be greeted by hundreds of dolls, some rotted and moldy, some hanging from trees, and some that now have insect nests in place of limbs. Local legend has it that a hermit isolated himself on this isle, and that the man claimed to be haunted by a girl who had drowned in the canal. To appease her spirit, he began collecting dolls and hanging them around the island. The hermit supposedly died in 2001 in the same way as the girl—by drowning in the canal.

Musophobes (those afraid of mice and rats) should avoid this temple at all costs. The Karni Mata Temple in India is a Hindu shrine built to honor the rat goddess of the same name. Worshippers believe that souls of the goddess' devotees are reincarnated as rodents, so all of the 20,000 rats that live in the temple are considered sacred. Watch your step in here—if a rat is killed, it must be replaced with a gold or silver statue. Besides, having a rat run over your feet in the temple is considered good luck (and no shoes are allowed inside).

Deep in the dark cavern underneath a pottery store lies thousands of disembodied locks of hair. A Turkish potter/artist Chez Galip supposedly started The Hair Museum of Avanos over 30 years ago, and the collection has grown to include more than 16,000 pieces of hair, all of which are tagged with the name and address of the donor. Leave your own contribution when you visit—twice each year, 10 pieces of hair are chosen at random from the museum. These lucky lottery winners will receive an all-expenses paid trip back to Turkey to participate in the artist's workshops.

After the Soviet Union fell in 1991, the statues of Lenin, Marx, and Stalin went down with it. Rather than be destroyed, though, some of these monuments were saved and put on display in Memento Park Budapest. Here you can see salvaged statues as well as replicas of former monuments. To add to the eeriness, there's also a replica of Stalin's former parade-watching grandstand and a mock central square (to represent the real-life squares where many uprisings took place across the region).
