Highland State Rec. Area has 4 different MTB specific loops you can attempt, A,B,C, and D, for a total of 16 miles. B and D loops both link to the A loop, while C loop is accessed from the B loop. A loop is a 3.8 mile warm up that connects to a 5.9 mile B loop (or you can bail after the loop). Both A and B are medium speed to slow, tight, and technical. They both trend towards a intermediate or expert rider.
C and D loops are
definitely expert level trails. C
loop is a 2.4mile which is accessed from the B loop. It is the rockiest
of the sections, this is apparent by the (see image left). many turns
filled with grapefruit sized stones, and towards the end of this torture
is a long burning climb with some switchbacks. You exit C right were you
began, then head back on B to either finish for the day or try your luck
