(CNN) — Four decades after it began as a penniless backpacker's bible to traveling on the cheap, Lonely Planet is publishing what it says is the definitive guide to the world's top tourism attractions.
The publisher has assembled a crack team of travel authors and experts to compile its "Ultimate Travel" list, ranking "mega-sights and hidden gems in a definitive wish list of the 500 best places to visit on earth."
While many are best-of list regulars, culled from UNESCO's World Heritage roster or, indeed, Lonely Planet's own country-by-country highlights, there are a few surprises.
And so the top 20 list finds Tasmania's Museum of Modern and Old Art and Fez's Medina rubbing shoulders with travel titans such as the Grand Canyon and the Taj Mahal.
'Most compelling places'
In pole position is the temple complex at Angkor in Cambodia -- which LP says "won by a landslide" -- followed by Australia's Great Barrier Reef and Peru's Machu Picchu.
Others to make the top 20 include Rome's Colosseum, Istanbul's Aya Sofya mosque and Australia's coastal Twelve Apostles rock formations.
"This book has been years in the making and brings together the most compelling places in the world according to our team," Lonely Planet's Editorial Director Tom Hall says.
"Every traveler has a list of places they simply have to see. Of course, what makes a place special is different for everyone, but this is our definitive list and one we hope will inspire many other travel wish lists."
Billed as the "only bucket list you'll ever need," the attractions have been gathered into a lavish tome, complete with write-ups, photos and gold foil print.
Looks good, but anyone hoping to hit all 500 is probably best advised leaving it on the coffee table rather than hauling it around in their backpack.
Here's LP's top 10 :
Lonely Planet says: The world's greatest temple to the Hindu god Vishnu, the magnificent monument of Angkor Wat is the crowning glory in a complex of more than
1000 temples, shrines and tombs that forms a virtual city of spires in the jungles of northern Cambodia.
Lonely Planet says: Stretching more than 1,860 miles up the northeastern coast of Australia, it's home to the world's largest network of coral reefs and thousands of species of fish and marine life.
Lonely Planet says: It's not the outrageously dramatic Andean setting, nor the way that the city clings to impossibly precipitous slopes that makes Machu Picchu so mind-blowing -- it's the fact that no one really knows what happened here.
Lonely Planet says: It's a myth that it can be seen from space, but this awe-inspiring maze of walls and fortifications stretching for an astonishing 5500 miles across rugged landscape seems both infinite and indestructible.
Lonely Planet says: Acres of shimmering white marble, a few thousand semiprecious stones carved and inlaid in intricate Islamic patterns, all in perfect symmetry -- the breathtaking mausoleum is architectural perfection.
Lonely Planet says: Look down at two billion years of geologic time and you'll see why the mile-deep, 277-mile-long phenomenon is nature's cathedral.
Lonely Planet says: This massive 50,000-seat amphitheater is Rome's most thrilling sights, and a monument to raw, merciless power, which can still be felt today by anyone who steps foot inside.
Lonely Planet says: The Guarani name for them is a huge understatement: Big Water. They're so enormous, tour boats in the foaming pools below look like matchsticks to viewers from the boardwalks above.
Lonely Planet says: Sheer red walls set against a mountain backdrop, the palace complex dominating Granada's skyline is perhaps the most refined example of Islamic art anywhere in the world, and the most enduring symbol of 800 years of enlightened Moorish rule in medieval Spain.
Lonely Planet says: Church, mosque and museum in one, Istanbul's Aya Sofya defies easy categorization. It was built almost 1,500 years ago when Byzantine Emperor Justinian I demanded a cathedral that would mimic the majesty of the heavens on earth and eclipse the wonders of Rome.
