Yanji to Changbaishan

I am flying from Beijing to Yanji later this month (June 2013). My plan is to go from Yanji to Changbaishan by public transportation. Do you have any recommendations about how to do this? I've read about buses, trains, and taxis, but don't have a definitive sense of the most reliable way to get around. Several of my Chinese friends have expressed their concern that it's a dangerous and difficult drive from Yanji to Changbaishan, so any advice would be appreciated! Thanks in advance for your help!
