East of Pinetop in the White Mountains, the Blue Ridge Cave Trail (#608), also known as Ice Cave Trail, is accessed off the Blue Ridge Trail about one-half mile or so north of Trailhead #1. It descends about 3.5 miles past Scott Reservoir and on to Porter Mountain Road, about a mile from Timber Mesa. It is very rocky in spots and is best ridden downhill. One part of the trail goes through a seasonal bog, so it can get interesting in wet weather.
The cave is really a lava tube. There isnt any ice in the cave, but the air leaving the cave is quite cool, about 52 degrees. The cave is fenced off, but...
When you get to Scott Reservoir, you will come to a T. The marked trail goes left. An unmarked trail goes right. Go straight and get wet. It is worth the short side trip to the right. That trail takes you through the trees to the end of the lake. When the water is high, it is a very nice side mountain bike ride.
Overall, Blue Ridge Cave Trail is the 34th most popular mountain bike trail of all 103 mountain biking rides in Arizona.
