A short walk, a final 100 ft climb and a cave. This hike starts at the NCAR parking lot. Head west to the Mesa trail and cross it by the information sign. There are lots of offshoot trails, be sure to follow the signs to the final 100 ft rock climb. If there is no ice or snow proceed up to the cave. NOTE: The cave is seasonally CLOSED from April 1 to October 1 for roosting bats.

liked the hike, the trail was not too hard for my 11 year old either. I had hoped I
the trail would end somewhere with a great view but it was not too bad.

A little, not too, challenging and there's a lot of shaded area. Last bit is probably the roughest. I will be going back!

Fun short hike. Not as much foot traffic as Mesa trail or Bear Peak so the course of the trail is difficult to follow at times. Very rocky, but a few great views of mtns and the valley. My phone showed 2.2 mi to top,
