Outdoors the Bayou City

Memorial Park is about 1,500 acres of pine forest, prairie and bayou edge on land that was Camp Logan, a World War I Army training camp. After the war, Will and Mike Hogg bought the ground and sold it to the city at cost in 1924 as a memorial to the soldiers. Since 2018 a ten-year plan, launched with a $70 million Kinder Foundation gift, has been remaking it. The Clay Family Eastern Glades opened in July 2020 with the 5.5-acre Hines Lake, boardwalks, wetland paths and picnic pavilions. The Kinder Land Bridge followed in February 2023: a 35-foot-tall green hill that carries trails and restored Gulf Coast prairie over Memorial Drive, which now runs underneath through two tunnels. Walk to the Overlook Pavilion near sunset and the Uptown towers rise over the grasses. Runners know the park for the 3-mile Seymour Lieberman Exercise Trail, one of the busiest loops in Houston.

Around sunset, the underside of the Waugh Drive bridge over Buffalo Bayou starts to stir. Then Mexican free-tailed bats begin dropping out of the crevices, first a few, then a dark ribbon that twists along the bayou and rises over the trees. Buffalo Bayou Partnership puts the summer population at roughly 300,000, the largest bat colony in Houston. Unlike many Texas colonies that leave for Mexico in the fall, these bats have been found under the bridge in every month of the year, though nights below about 50 degrees can keep them roosting. Each one can eat up to two-thirds of its body weight in insects in a night and may fly more than 60 miles round trip. Watch from the observation deck at Allen Parkway and Waugh Drive, or look down from the bridge itself. On spring and summer evenings, hawks sometimes work the edges of the swarm.

About an hour southwest of downtown, Brazos Bend is where Houstonians go to see American alligators in the wild, often hauled out on the bank a short distance from the trail. The roughly 5,000-acre park spreads across Brazos River bottomland: lakes, marsh, coastal prairie and bottomland forest, laced with 37 miles of trails. The 1.2-mile 40-Acre Lake Trail is the classic walk, flat and wide, with an observation tower on the lake. The 1.7-mile Elm Lake Loop is just as good for gators and wading birds. More than 300 bird species have been recorded here. After dark, the Houston Museum of Natural Science opens the George Observatory inside the park on Saturday nights; its biggest instrument is the 36-inch Gueymard Research Telescope. The one rule to take seriously: stay at least 30 feet from alligators and never feed them.

On the western edge of Memorial Park, separate from it in spirit if not on the map, the Houston Arboretum & Nature Center is a 155-acre sanctuary for native Texas plants and the wildlife that follows them. The city set the land aside in 1951 as an arboretum and botanical garden, and ground was broken on the Aline McAshan Botanical Hall in 1967. Today five miles of trails thread through forest, restored savanna, wetland, ponds and meadow. The 1.76-mile Outer Loop is the best single walk; the half-mile Ravine Trail adds stairs, bridges and a real drop in elevation, rare in flat Houston; the short Donor Boardwalk winds past South Woodway Pond, and the Couch Birding Trail ends at a platform over Buffalo Bayou. Inside the Nature Center, the Discovery Room has hands-on exhibits for kids, and there is an outdoor Nature Playscape too.

Discovery Green was a spread of downtown surface parking lots until 2004, when the city and a group of local philanthropies bought the land. The 12-acre park opened on April 13, 2008, designed by Hargreaves Associates, and an estimated $1 billion in towers, hotels and housing has gone up around it since. Kinder Lake covers more than an acre, with kayaking on the water and, each winter from November into February, an ice rink laid over its model boat basin. The Gateway Fountain throws 14-foot arcing jets across a sloping granite plaza where hundreds of kids cool off on summer days. In the gardens, Doug Hollis's Listening Vessels are two concave limestone sculptures that carry sound: speak softly into one and a friend at the other hears you. Look too for Margo Sawyer's Synchronicity of Color, painted metal boxes cladding the garage stair towers, and Jean Dubuffet's Monument au Fantome. This fall the Houston Pumpkin Festival runs through November 8.

For most of its history Houston was a big city without a botanic garden. That changed in 2020, when the Houston Botanic Garden opened on 132 acres in the Park Place neighborhood, on the site of the old Glenbrook Golf Course. Sims Bayou curls around the property, so the walk has a wilder edge than a manicured city garden: native Coastal Prairie grasses and Stormwater Wetlands sit alongside the designed beds. The Global Collection Garden gathers plants from around the world, the Culinary Garden grows edible and medicinal plants, and the Pine Grove and Woodland Glade give you shade on hot afternoons. Families head for the Susan Garver Family Discovery Garden, with simple water machines and a boardwalk maze around a lagoon.

The coast as it was before Houston: tallgrass prairie, wetland forest and a wild bayou, more than 4,300 acres of it between NASA's Johnson Space Center and the Bayport industrial district, the largest urban wilderness preserve in Texas since it grew in 2024. The bayou is one of the last in Texas that has not been channelized, and alligators bask along it, seen from the boardwalk and the Bayou Ranger II pontoon. Coastal tallgrass prairie once covered at least nine million acres of Texas and Louisiana; more than 99 percent of it is gone. The center keeps 900 acres, with bison, the prairie's original architects, grazing beside it. Armand Yramategui, curator of the Burke Baker Planetarium, was killed in January 1970 driving out of town to see a comet; Middle Bayou was renamed for him, and Hana Ginzbarg led the campaign that saved it. Martyn Farm's 1895 farmhouse survived the 1900 Storm and crossed Clear Lake on a barge in 1982.

Hermann Park turned 100 in 2014, and McGovern Centennial Gardens was its birthday present to the city: eight years of work and $31 million, opened in December 2014 on the site of the old Houston Garden Center. The 15 acres are free and laid out as a series of rooms. The Garden Mount, a 30-foot green hill you can walk to the top of, anchors the view. Around it are a Rose Garden planted with tough Earth-Kind antique roses, an Arid Garden, a Woodland Garden, a Family Garden and a Celebration Garden, with 650 azaleas, 490 trees of more than 50 species and 55,000 bulbs across the grounds. The Hawkins Sculpture Walk lines up busts and statues of Simon Bolivar, Benito Juarez, Jose Marti, Confucius, Mahatma Gandhi and Martin Luther King Jr. The sculpture Dawn (1971) came over from the old Garden Center, a small link to what stood here before.

Levy Park shows how much a small city park can hold. The land came to Houston through a 1941 bequest from the estate of Leon Levy. In 2015 the Upper Kirby Redevelopment Authority and the Upper Kirby District Foundation began a rebuild designed by the Office of James Burnett with Natalye Appel and Associates Architects, and the 6-acre park reopened in 2017. Now there is a Children's Park with a climbing wall, slide and water feature, a dog park with separate areas for big and small dogs, an event lawn ringed by live oaks, a 22,000-square-foot activity lawn and a boardwalk overlook up in the oak canopy. Food is on site at Hearsay Levy Park and Gaspachos Mexican Bites. The free calendar is the draw: yoga and tai chi mornings, Argentine tango nights and Sunset Bingo on second Fridays.

For a first look at the Texas coast that is not a seawall and souvenir shops, drive about an hour south to Galveston Island State Park. It spans the island's West End from the Gulf of Mexico to West Bay, roughly 2,000 acres of beach, dunes, coastal prairie, salt marsh and bayous. The beach side is quieter than the city's beaches. Cross FM 3005 to the bay side for the trails: the 1.2-mile Clapper Rail Trail for wading birds, the 1-mile Alligator Loop around a freshwater pond, and the 3.3-mile Prairie Trail through the island's original landscape, with two observation towers along the way. Paddlers can follow marked routes like the 3.3-mile Jenkins Bayou trail. More than 300 bird species have been recorded, and in 2022 the park found its first Kemp's ridley sea turtle nest in a decade. Hurricane Ike battered the park in 2008. The beach side was rebuilt over three years for $24 million and reopened in June 2022. Look for the Eskimo Curlew sculpture, a memorial to a lost shorebird.
