There can be lots of great riding in and around Ishpeming, as mentioned the trail Big bay is a blast, but be prepared to work, its not a railroad grade, its curvy and you work to go at speed, heading east to Marquette and south towards Gwinn is fun to, there is a lot east of Harvey, but that means traveling 8 and that can be a bear late in the day on your return with the trail whooped out. heading further east towards Munising is mostly high speed rail beds. I like to go south on 7 towards the Buckhorn and do the trails that head to Rapid river, low traffic and nice trails most of the time. Heading west and North have generally been rougher as the snow always seems to thin, but in a good snow year whoi knows? Have fun. My Friends have a Camp in Chattam we base out of called Bohemian Creek House, look it up as a rental. They have two houses on one property, one is a three bedroom house with full ammenities, and the second is a bunkhouse with one room with four bunks, and a large wraparound couch that has a queen pullout beds. both have 1 1/2 Bathrooms, full kitchens etc. all rehabbed two years ago.
