There are several rides from the upper end of the 12 Mile road.
The map is of a fun and challenging loop right from the gate up to 12 Mile Meadows.
12 Mile Meadows Loop at EveryTrail
From the 12 Mile gate to North Basin is only about 5 miles. North Basin offers lots of exploring at the top of the Lemhi Range.
Another great ride is to follow Warm Springs Creek down to Lime Creek.
All of our maps show a trail in Meadow Creek. If that is still there and ridable, there is another option for loops and North Basin or Lime Creek access.
Look for a 12 Mile section at the top of the page soon.
