We stopped on the spur of the moment, just hoping to take a peek. However, this place was so remarkable, our family of four just HAD to dig out our swimwear from our packed bags and take a dip. The cars in the lot seemed evenly divided between out-of-state road trippers like us and devoted NM locals, but it didn't seem too crowded. Even if you don't venture into the crystal clear water, it's fun to watch the jumpers and divers. And, the water is truly a mesmerizing blue. We were so mesmerized, our "quick peek" turned into an extended stop of a couple hours. On a hot, dry day, this backyard-sized hole is a godsend to the weary interstate traveler. There were a number of conscientious lifeguards there, but parents should take a good look at the rock formations with any prospective young jumpers. You know, "look before you leap" really applies here. The stairs leading down into the hole are a little slippery with algae, so proceed with caution. You can stand on a ledge with the water surface at adult torso level, or tread water above the deeper area. I selfishly sent my husband and two young children to the shaded picnic tables while I enjoyed an extended float. (Parents will recognize the importance of maintaining a modicum of serenity during a cross-country trek.). Don't miss this FREE experience. Honestly, it's a wonder this area hasn't been appropriated by some money-grubbing agency and turned into some new age spa retreat. You'll have to make a stop to stretch your legs and find a restroom at some point on your road trip. Pack a lunch and see the Blue Hole!
