Balmorhea State Park

Balmorhea State Park’s recreation centers on its extraordinary spring-fed pool — swimming in the crystal-clear, constant 72°F water of the world’s largest spring-fed pool, snorkeling and scuba diving in the deep, clear pool (a popular dive site, with certification and equipment available nearby), watching the endemic pupfish and other aquatic life, and relaxing in the shaded motel courts around the pool. The surrounding park offers camping, the desert landscape of the Trans-Pecos, and proximity to the Davis Mountains and Big Bend. Swimming, snorkeling and the unique experience of a vast, crystal-clear natural pool in the middle of the Chihuahuan Desert are the park’s irreplaceable draws.

The pool is magical year-round — its constant 72°F water is refreshing in the summer heat and pleasantly mild in winter, though the park is busiest in summer when the desert heat makes the cool spring water most inviting. Spring and fall offer comfortable air temperatures with fewer crowds. The pool may have capacity limits on peak summer weekends, so reservations and early arrivals are recommended. The surrounding Davis Mountains and Trans-Pecos are beautiful in any season. Visit in summer for the full desert-oasis experience, or in spring and fall for a quieter swim and the pleasure of the Davis Mountains countryside.

The San Solomon Springs at Balmorhea have been a water source and gathering place since Native Americans used the cienega, and the springs made farming possible in the remote Trans-Pecos, sustaining the small community of Balmorhea. In the 1930s, the Civilian Conservation Corps built the great pool, the motel courts and the park infrastructure, creating one of the most distinctive CCC projects in the state system. Named for the towns of Balmorhea (itself a portmanteau of three early landowners’ names), the park quickly became a beloved desert oasis. Today the park and its historic CCC pool are a State Historic Landmark, and the springs remain a precious and diminishing desert water resource.

The San Solomon Springs at Balmorhea flow from the Rustler Aquifer — a deep, pressurized limestone aquifer that receives recharge from the surrounding desert mountain ranges and discharges at the springs, which flow at about 26 million gallons per day, creating the oasis in the Chihuahuan Desert. The springs and the cienega they feed are a classic desert oasis feature — a place where groundwater reaches the surface in an otherwise arid landscape, sustaining life and creating a distinctive microhabitat. The surrounding landscape is the classic Trans-Pecos basin and range, with volcanic and limestone mountains rising from desert valleys in one of the most geologically diverse regions of Texas.

The San Solomon Springs and their crystal-clear pool and cienega (desert marsh) harbor remarkable and rare aquatic life, including the Comanche Springs pupfish, a federally endangered species found only here and in a few other springs of the Trans-Pecos, along with other endemic and uncommon aquatic species adapted to the constant spring water. The surrounding desert and the nearby cienega attract birds, including migratory species drawn to the rare desert water, and the Davis Mountains provide a backdrop of mountain wildlife. The pupfish, visible in the clear pool, are a beloved and ecologically significant resident of this rare and precious desert spring.

Balmorhea State Park protects one of the rarest ecosystems in the Chihuahuan Desert — a natural desert spring and cienega — and the endemic aquatic life it supports, including the federally endangered Comanche Springs pupfish, which exists only in these springs and a handful of other Trans-Pecos spring systems. Desert spring ecosystems are among the most isolated and ecologically significant habitats in the American Southwest, each spring a unique island of life in a sea of desert. The San Solomon Springs face long-term threats from groundwater depletion in the Rustler Aquifer. Protecting the springs, the water flow and the endemic pupfish is a critical conservation priority for this rare desert oasis.

Balmorhea State Park holds an almost mythic place in the Texas imagination — the vision of a vast, crystal-clear swimming pool in the middle of the Chihuahuan Desert, fed by an ancient aquifer, is so unlikely and so wonderful that it captures the hearts of all who see it. The great CCC pool, the adobe-style motel courts, the constant cool water in the desert heat, and the endemic pupfish gliding in the clear depths have made Balmorhea a beloved and irreplaceable Texas destination. The park embodies the surprising, life-sustaining beauty of the desert spring oasis, a treasured and historically resonant gem of the far West Texas landscape.

Balmorhea State Park is in Reeves County in the Trans-Pecos region of far West Texas, on TX-17 about 4 miles south of the town of Balmorhea, roughly 45 miles north of Fort Davis and the Davis Mountains. A park entrance fee applies; reservations for swimming and motel courts are recommended and may be required on peak weekends. The park offers the world’s largest spring-fed pool, the historic CCC motel courts (overnight accommodations), a campground, and cienega viewing. Swimming may be subject to capacity limits. Check Texas Parks & Wildlife for reservations, swim availability and current conditions before visiting.

Texas Parks & Wildlife protects the San Solomon Springs, the great pool, the cienega and the endemic Comanche Springs pupfish of Balmorhea State Park. The pupfish and the spring ecosystem are fragile — visitors help by not disturbing the pupfish (do not touch, chase or harass them), following all pool rules, not using sunscreen or lotion in the pool (chemicals harm the aquatic ecosystem), staying out of the cienega and protected areas, not introducing any foreign organisms, packing out all trash, and respecting the water quality of the spring. Protecting the springs, the water flow and the endemic pupfish is essential to the survival of this rare desert spring ecosystem.

Balmorhea’s pool is large, deep in places (to about nine feet in the scuba area) and can have currents near the spring outlets — non-swimmers and children should stay in shallower areas, and life jackets are recommended for weak swimmers. The pool can reach capacity on peak summer days; arrive early or have a reservation. The surrounding desert is hot and dry in summer; carry water and sun protection outside the pool area. The Trans-Pecos is remote; come self-reliantly with fuel and supplies for the drive. Scuba diving in the pool requires proper certification and equipment; follow the park’s dive rules strictly.

A park entrance fee and reservations are recommended and may be required. Do not use sunscreen, sunblock or lotion before entering the pool (protects the endemic fish and water quality). Do not touch, chase or disturb the Comanche Springs pupfish. Stay out of the cienega and protected habitat areas. Scuba diving requires certification and follows specific park rules. No glass containers in the pool area. Pets are not allowed in the pool. Camp only in designated areas; motel courts require advance reservations. Pack out all trash. Check Texas Parks & Wildlife for current rules, capacity limits, and reservations before visiting.

The Davis Mountains — the most extensive mountain range in Texas — and Davis Mountains State Park with the Indian Lodge lie about 45 miles south, along with the McDonald Observatory on Mount Locke (a premier public stargazing facility), Fort Davis National Historic Site, and the Gateway to Big Bend country. The town of Fort Davis, the Trans-Pecos basin and range, and ultimately Big Bend National Park to the south form the broader region. Balmorhea anchors a rich and beautiful corner of the Trans-Pecos, paired naturally with the Davis Mountains and McDonald Observatory for an extended far West Texas adventure.

Go early — especially on summer weekends, the pool can reach capacity and latecomers may be turned away. Do not wear sunscreen or lotion in the pool (it harms the water and the pupfish), watch the endemic Comanche Springs pupfish and other aquatic life in the clear water (snorkel for the best view), and take time to absorb the extraordinary experience of swimming in a vast, 72°F spring-fed pool in the middle of the Chihuahuan Desert. Stay in the historic CCC motel courts for a full experience, combine with the Davis Mountains and McDonald Observatory, and book reservations well in advance for summer visits.
