The Barham Ridge Trail is a wide, double-track path that is popular with hikers, trail runners, and mountain bikers. This is an area to slow down as it connects to multiple trails and can often get busy near Robbers Peak. It is very sun-exposed with little shade, so be sure to pack some sun protection.
