A spring on the eastern side of the Sandia Mountains. To find this spring, take highway NM-14 six miles north from where it meets I-40. At the town of Sandia Park, turn west onto NM-536 and follow this for about eight miles, then turn right into a parking lot marked by signs for Capulin Spring Snow Play Area. Immediately inside this parking lot, turn right and park, the paved trail to the springs begins at a gate at the eastern [lower] end of the parking lot. Walk down this trail about .15 miles until you see two benches and a fenced in area on your left side. The spring is immediately below the fencing.
I visited in early June and the flow was slow (about 25 minutes to fill 5 gallons of water) but I’m told the flow fluctuates throughout the year. Be aware you will have to carry containers .15 of a mile to get to the spring itself from the parking lot. Water runs out of a PVC pipe from the source. Larger containers won’t fit. I used a half-gallon water bottle and then transferred that water into my containers.
There is a $3 honor system pay station to park in the lot.
I’m not aware of this water having been tested.
