Biggest Rock Festivals in the world

(CNN) - More than 160, 000 people flocked to the tenth Coachella music festival in April, signaling the start of the annual summer music festival season worldwide.

Bestival, on the Isle of Wight, was voted last year's "Best Lineup" in the UK.

The equivalent of a small city materialized for three days amid the searing heat and palm tree lined fields in east California, featuring performances from Paul McCartney, Leonard Cohen, and TV on the Radio.

From silent disco parties at Bonnaroo in Tennessee to all-night raves at Serbia's Exit festival, our guide prepares music fans worldwide for another year of summer music festivals in the sun.

BONNAROO, Tennessee, U.S.
June 11-14 ($235)

The word "bonnaroo" is New Orleans slang for "the best on the streets, " and the Bonnaroo festival has grown into that name over the past eight years, winning Rolling Stone magazine's "Best Festival" award in 2008. In addition to promoting mainstream and independent rock, hip-hop, and electronic groups, Bonnaroo also features a stand-up comedians' tent and a "silent disco" tent - where everyone gets a pair of headphones that sync up with the music for late night dancing without the noise complaints. Over 80, 000 people will head to the festival outside of Nashville to see headliners including Bruce Springsteen, Phish, and Snoop Dogg.

GLASTONBURY, Somerset, England
June 24-28 ($255)

Glastonbury has been around since dairy farmer Michael Eavis first held a free-two day festival on his farm in 1970, and it's long been the festival in England for seeing the biggest and best bands in the world. It also may be the muddiest - heavy rain in several years, most notably 1997, turned Glastonbury into a muddy bog. Everyone from Radiohead to Jay-Z has headlined the festival, and with over 700 acts each year, there is something for everybody, and some of the proceeds from the festival go to Oxfam and Greenpeace. This year's headliners include Franz Ferdinand, Blur, and Bruce Springsteen.

ROCK AL PARQUE, Bogota, Colombia
June 27-29 (free)

The Rock al Parque festival, launched in 1995, has become South America's biggest rockfest in recent years - some 320, 000 people traveled to Simon Bolivar Park in 2006 for a weekend of Colombia's biggest rock bands and renowned international headliners. Funded by Colombia's culture secretary, the free festival has included some of rock's biggest names, including Black Rebel Motorcycle Club, Manu Chao, and Bloc Party. In the days leading up to Rock al Parque, the festival organizers host a series of panel discussions on music production, management, and the recording industry.

ROSKILDE, Denmark
July 2-5 ($220)

Since 1971, the rock festival in Roskilde has hosted the biggest names in music, from Bob Marley to Bob Dylan. It is the biggest summer festival in northern Europe, and the "Arena" stage boasts a 17, 000-capacity tent, the largest in Europe. The festival boasts a daily newspaper and a 24-hour live radio station, and is also home to the annual "Naked Run, " where the first naked person to cross the finish line receives a free ticket for next year's festival. Some 80, 000 will travel to Roskilde to see headliners including Coldplay, Oasis and Nine Inch Nails.

EXIT, Novi Sad, Serbia
July 9-12 ($105)

THISDAY, Abuja/Lagos, Nigeria
Dates tbc

FUJI ROCK, Naeba, Japan
July 24-26 ($410)

Japan's biggest outdoor festival takes its name from Mt. Fuji, the site of the first festival in 1997. Fuji Rock has been set amongst the cool forested mountains of the Naeba ski resort for the past ten years - gondolas and hilly trails transport people from stage to stage, and the streams and forests between them are the reason why Fuji Rock has been called the most beautiful festival in the world. It's not just about the scenery, though - over 100, 000 people will trek through the mountains to see headliners Franz Ferdinand, The Killers, and Weezer.

LOLLAPALOOZA, Chicago, U.S.
August 7-9 ($190)

Rocker Perry Farrell began Lollapalooza in 1991 as a farewell tour for his band, Jane's Addiction. The biggest grunge rock festival during the nineties disappeared for awhile around the turn of the century, but it was revived in 2005 as a more traditional "big weekend" destination festival in Chicago. The past few years at Grant Park have been marked by hot summers, huge crowds, and even bigger bands. The anticipated crowd of nearly 200, 000 is staggering, as are this year's headliners: Kings of Leon, Tool, Depeche Mode, and Beastie Boys, just to name a few.

BESTIVAL, Isle of Wight, England
September 11-13 ($205)

The trendy Bestival, the original boutique weekend festival on the Isle of Wight, is the best way to end the summer festival season in Europe. Bestival boasts a yearly fancy dress competition - last year was "30, 000 freaks under the sea, " and 2009 is the year of "Outer Space, " so make sure to dress accordingly. Thousands of Bestival-goers will witness an eclectic lineup including Lily Allen, Massive Attack, and MGMT in the picturesque surroundings of Robin Hill Park. For family fun, look no further than Camp Bestival, a three day family festival at a castle by the sea in July.

PARKLIFE, Australia
Late September-Early October

The Parklife one-day music festivals kick off the summer festival season across Australia. The dance-focused fests have featured heavyweights Justice, MIA, and Muscles over the past two years. The day-long festivals are followed by an official "After Life" party that runs until the early hours of the morning, so be prepared for a long one if you're one of the estimated 100, 000 people attending a Parklife gig in one of capital cities across Australia at the end of September.

WOODSTOCK, Cape Town, South Africa
Late Fall 2009

When people think of Woodstock, Cape Town isn't necessarily what comes to mind. But for the past decade, the South African festival has been the biggest youth music event in the country, hosting a variety of both well-known and upcoming mainstream and hip-hop acts - not to mention a variety of extreme sports stunt acts, paintballing, and flea-market stalls. Woodstock may not have the star power of the legendary American festival - but with the wide range of music and outdoor activities it presents, its promoters aren't lying when they say that boredom simply isn't an option.

Sunburn Festival launched in December 2007 as south Asia's first electronic music festival, and featured heavyweights like Carl Cox and John '00' Fleming. Located seaside in Goa, on India's west coast, the festival has its roots in "Goa Trance, " a type of pulsing, transcendental electro music that became popular in the early 1990s. Sunburn again treated over 5, 000 electro revelers to a three-day party by the beach in December 2008. The festival's founder has said Sunburn will always be free to attend, and it is not to be missed if you happen to be in India in December.
