Took the CNM Shuttle to the trail head and spent the day gawking back down to the Visitor Ctr. Heart of the Rocks was a fun scramble. As a loop we chose to stash the packs for a lighter freer stride. Another tough hiking trail 10 steps gawk, 20 steps gawk some more etc... especially if you have a camera in hand. To enjoy the Chiricahua National Monument double any of your standard hiking times. Stayed in the campground which is nice and handy. Sites are close together tho.
