I have rode Bull Gap and i like the south east end around Goodars.
There were some hills and mud to dig around in.
Are any of these trails better than bull gap for hills and mud?
St Helen (43)
Gladwin (46)
Denton-Leota (42)
Huron (D)

 

Broken paw

you MUST run Gladwin next month if your looking for mud .....
the NW loop is VERY muddy and has a 1/4 mile water alley run and a nice creek crossing !!!
this place was a mess 3-4 years ago ( the way I liked it ) ... since they've added MANY bridges to help out the 2x4's !!!

St. Helen.. has a 1000 acres scramble area ,,,, some short but steep hills ... typ. no mud

denton-leota are 2 different systems ..... they also connect to St. helen now too !!!! great fast connector run
leota has a big hill in the center of the system ( marker 11 ) i believe

denton can get really muddy this time of year also !!!

Huron is a sandy sno-mo trail ( route all the way ) no loop

I too agree I like the southern side of Bull Gap ( besides the hill )

Have fun !!!
