In contrast to the rugged Organs seen to the east, this loop is rolling and fast, making it easy to open up your cadence and hold a steady pace. There are some short and gradual climbs, but none are long and sustained enough to warrant trekking poles or aggressive trail shoes. That said, if you need some extra vert, other intersecting trails lead to the mountain's official summit, though the BLM and NMSU ask you "keep a reasonable distance" from the communication towers and observatory at the top.

According to the BLM, "Tortugas Mountain has long been used for mining, ranching, recreation, tribal ceremonies, and scientific studies," and there is currently a massive "A" visible on the mountain's summit - a tribute to New Mexico State Aggies based in Las Cruces.

The area is managed by the Bureau of Land Management (BLM) and is open year-round, though the summer heat may be unbearable for some. Vault toilets and maps are available at the trailhead, but not water. Dogs are welcome to join, though wildlife - especially rattlesnakes - may warrant leaving your 4-legged companion at home during the warmer months.
