Welcome to TOMMBA

TOMMBA is your local non-profit mountain biking organization serving Charlevoix and Emmet Counties, which includes the cities of Boyne City, Charlevoix, East Jordan, Harbor Springs and Petoskey.  TOMMBA is dedicated to creating, enhancing and preserving great trail experiences for riders of all levels.  100% of your dues go to developing and maintaining sustainable mountain bike trails.

"We love your trails! Every year we come visit my dad in TC we look forward to riding your trails. We have ridden all over the US and BC in Canada and this is one of the best trail systems we’ve ever ridden! Thanks for building it and maintaining it so well. We were there a month after the ice storm and you guys really did an awesome job getting it opened up.”
