The 4 Best Swimming Holes in New Mexico

A swimming hole in the middle of downtown is a rare thing, and that's exactly what Lake Carlsbad Beach Park delivers. The Pecos River is dammed here into a calm, lake-like pool that runs right through Carlsbad between the railroad bridge and the upper Tansil Dam, and the city maintains a designated swimming area within its 125.6-acre recreation area along the banks.

You share the water with boaters and anglers, but swimming is an official, ongoing use of this stretch of river. The city even confirmed in a July 2026 notice that swimming stays safe during its routine aquatic vegetation treatments. With the Beach Bandshell, boat docks, playgrounds, and picnic areas all in the same park, it works as an easy cool-off stop in a desert city.

Spence Hot Springs is one of the most visited backcountry hot springs in the Jemez Mountains, and once you see the setup you understand why. A series of small primitive pools terraces down a forested hillside above the Jemez River, with the top spring running around 109 degrees, a cave-spring pool near 100, and lower pools cooling to roughly 95. This is a soaking spot rather than a swimming hole, shallow sandy-bottomed pools where you sit and steam rather than swim laps.

Getting there takes a little effort. From the big parking area on NM Highway 4 it is about a quarter mile of easy trail, but you have to wade across the Jemez River and scramble up a rocky, sometimes slippery embankment to reach the pools. Expect company, this place gets heavy use, and go in with your head literally above water. Naegleria fowleri, a rare but potentially fatal amoeba, has been documented here, so keep the water out of your nose.

Montezuma Hot Springs is a free cluster of natural geothermal soaking pools along Gallinas Creek just outside Las Vegas, New Mexico, more of a soak than a classic swimming hole. Roughly 20 to 30 thermal springs feed a mix of concrete pools and primitive mud-dug ones, with temperatures running from a mellow 94F all the way to about 120F in the aptly named Lobster Pot.

The pools sit creek-side in a small canyon at about 6,700 feet, near the historic Montezuma Castle on the United World College campus, whose nonprofit partner manages the site for public use. You come here to settle into mineral-rich water and stay a while, not to swim laps, and picking your pool by temperature is half the fun, from The Cube to The Toaster.

The Beach at Farmington Lake is the city-run swimming hole for northwest New Mexico, a sandy, fenced, lifeguard-supervised swim area on the 250-acre Lake Farmington reservoir east of town. Alongside the beach, the city operates a seasonal inflatable Aquapark with water trampolines, slides, and climbing features, with mandatory city-issued life jackets for that part.

Set your expectations on the water itself: a city lifeguard has described it as murky with poor underwater visibility, which is exactly why lifeguards watch swimmers more closely here than they would at a pool. It suits casual, supervised family swimming in high-desert country more than serious open-water laps.
