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.

This was an awesome trail!! However what’s not mentioned is that this is climb to Mallory cave and rocky in areas. Several switch backs. Beautiful, peaceful and a fair amount of foot traffic. Will definitely do again.

Great views along the trail! A must do. The bat cave was still padlocked yesterday, but it looked scary in there anyway! I thought a vampire would appear, lol.

Definitely some scrambling at the end getting to the cave as well as a narrow area you have to squeeze your body through. Great area to sit and see a birds eye view of Boulder!

Nice view, good balance of woods and open scenery. It has Streep parts but is definitely doable within 2.5 hours. I clocked 3.9 miles, 36 floors round trip.
