As we dust the snow off and begin to look forward to warmer weather, the time has come to make plans for one of country’s hottest festivals—Country Jam in Grand Junction, Colo.

Country Jam is a four-day country music festival that features over 30+ bands on three stages. This year’s line up includes headliners Kenny Chesney, Jason Aldean and Thomas Rhett; co-headliners Justin Moore and Randy Houser and supporting acts, Chris Young, Old Dominion, Frankie Ballard, Kane Brown and Sammy Kershaw.

Being billed as The Biggest Party in Colorado, the 26th annual Country Jam will take place June 15-18 at Jam Ranch, near Grand Junction, Colo.

Past performers of the festival have included Miranda Lambert, Florida Georgia Line, Montgomery Gentry, Lady Antebllum, Jake Owen, Keith Urban, Tim McGraw, Dierks Bentley, Toby Keith, Eric Church and more.

And you never know who may make a surprise appearance at Country Jam. Last year at the 25th anniversary, pop superstar Gwen Stefani showed up, joining 90,000 fair-goers, to wish Blake Shelton a Happy Birthday.

Tickets for Country Jam, which began in 1992 as an expansion of the successful Country Jam in Eau Claire, Wis., are on sale now. To purchase tickets, check out Country Jam’s website or download the official Country Jam App which features up-to-the-minute schedule and latest festival news.
