Spent 3 days in the Snake River " Hells Canyon" this is a big and wild area with great trails and roads to ride and no people execpt horses and cows and snakes (pack a gun). Pittsburg Landing is the place to go.
Or go to Wallace,Idaho check out the website for this area.

 

Kalsobc,

Where can I get information on the trails at Pittsburgh landing? Our ATV club is going to the ATV jamboree at Wallace in July. We are always looking for additional places to ride & camp.

 

looking at the map of Pittsburg Landing you will see that from the Salmon River it is 18 miles to Pittsburg landing. When you get near to the top of the hill there is a road which leads to riding areas. Heading down the hill towards the Snake River you will see dirt trails heading north which lead to riding areas.
Have fun and watch out for snakes.
