Bonnaroo in Manchester, Tennessee

Bonnaroo, which means “more than ever”, pretty much sums up this event. Touted as today’s Woodstock, this four day musical, comedy and arts camping festival takes place in June on a 700 acre farm and draws over 80,000 people each year.  It features some of today’s hottest artists like the Dave Matthews Band, Conan O’Brien, Jay-Z, Weezer, Kings of Leon and Stevie Wonder.  In addition to the musical performances, attendees are treated to comedy shows from Conan O’Brien and Margaret Cho, cinema shows, silent disco, yoga sessions and more. Special guest appearances, diversity of the lineup and community spirit is what keeps festival-goers coming back year after year.

Bumbershoot in Seattle, Washington

The Bumbershoot Arts and Music Festival is one of the last summer festivals of the year. It’s been held every year over Labor Day weekend since 1977. Bumbershoot’s the largest fest of its kind, and welcomes over 250 performers at over 20 unique venues. There’s music, comedy, film, performing and visual arts, dance, theatre, and even special events for the kids.

Lollapalooza in Chicago, Illinois

Another hot, annual summer concert, Lollapalooza features Green Day, Lady Gaga, Soundgarden, Social Distortion, MGMT and many more. A diverse lineup within the heart of Chicago is what draws people to this annual event that’s been taking place every August since 2005.  Over the top stages (Lady Gaga will have a $150,000 custom built stage this year) and VIP Cabanas complete with air-conditioning, private restrooms, gourmet buffets and spa treatments are a big draw. Due to city ordinances, the festival must end by 10:00pm each night, so bands are often times seen at area nightclubs and occasionally do after-hours shows.

Burning Man in Black Rock City, Nevada

Each year, tens of thousands of people gather together for one week in late August/early September in Nevada’s Black Rock Desert to create an experimental city. A theme is assigned (for 2010 the theme is Metropolis) and pretty much anything goes at this event. Part artistic, part communal, organizer Larry Harvey started Burning Man 1986 on a San Francisco area beach to encourage people to “come alive” via a common bond. Living conditions for the week are primitive – everything must be brought in, including food and water, nothing can be left behind, and the only commerce is gifting or bartering – but that’s just how people want it.

EAA AirVenture Show in Oshkosh, Wisconsin

Red Bull FlugTag in Miami, Florida

The Red Bull FlugTag competition/festival kicks off its summer tour this year in Biscayne Bay, Miami. Over 30 teams from across the Southeast will see if their engineering fêtes have paid off. Flugtag, which means “flying day” in German, is a competition that encourages all to design, build and pilot a homemade flying machine off a 30 foot high ramp. Festival-goers love watching the creative and often absurd human-powered craft dive into the water below. It seems every “aircraft” ends up soaking what, but what matters most may not be how well the machine actually flies – contestants are judged on creativity and showmanship as well. Additional 2010 events will be held in Long Beach, Philadelphia, and Twin Cities in July, August, and September.

Glastonbury Festival in Glastonbury, UK

The Glastonbury Festival , held every July, is considered the largest music and performing arts festival in the world. Made famous for music and mud (it rains a lot), this festival was begun the day after Jimmie Hendrix died in 1970. Set on 900 acres in the Vale of Avalon, many people travel here to tune in to the mythology and religious traditions. In fact, many believe this is where King Arthur is buried and that it holds ancient secrets and symbolism. The festival is broken out into different areas and villages with each as diverse as the next.  There is the Dance Village featuring contemporary UK dance music and The Green Fields which focuses on green living and where you can get a massage or take your turn pedaling to create electricity to keep the PA charged. The Pyramid Stage will host the largest acts which include artists as diverse as Willie Nelson, Snoop Dogg, U2 and Norah Jones.

Edinburgh Fringe Festival in Edinburgh, Scotland

The Edinburgh Fringe Festival is officially the biggest arts festival in the world and features all forms as art including theatre, comedy, dance and music. The event takes place over a three week period in August and kicks off with a huge parade known as the Cavalcade.  Beads are given out to parade goers like at Mardi Gras (but they can’t be thrown). Attendees to this event like that it is unjuried which means that there is no selection committee to decide who the performers will be so anyone can perform at this festival. While this means you’re not guaranteed a certain level of quality in the performances, it also allows for a lot of creative and experimental art that you might not get to see elsewhere.

San Fermin Festival (Running of the Bulls) in Pamplona, Spain

Over one million people come each year for the week-long San Fermin Festival that begins at 12:00 on July 6th with chupinazo (fireworks and rockets) at the town hall and ends at midnight on July 14th with the singing of the Probre de Mi, a hymn that marks the closing of the festival. The encierro, or the Running of the Bulls, is held at 7:30 a.m. each morning during the festival when six bulls are released onto the streets.

The biggest day of the festival however is July 7th when thousands of people, dancers and street entertainers follow a replica of the statue of Saint Fermin down the streets of Pamplona.
