The Tanagar Canyon Course is a location from The Legend of Zelda: Breath of the Wild. Located in Tanagar Canyon in the Tabantha Frontier region of Hyrule, it is the site of Boom Bam Golf. It is owned and operated by the Goron Modar.
Modar created the course some point after he rolled down into Tanagar Canyon. It is suggested that Modar is the Goron from the local legend of the Boom-Bam Ghost of Tabantha Great Bridge. Unbeknownst to the locals, Modar survived the fall thanks to his miner's hard hat and instinctively rolling into the canyon after falling off the bridge. Modar set up camp underneath the bridge and created the course to play Boom Bam Golf to alleviate his boredom.
