Walnut Springs Park
Designed by architect Robert H. H. Hugman and begun by Civilian Conservation Corps workers in 1933, this Seguin park follows Walnut Branch, a Guadalupe River tributary, with stone walls, walkways, and bridges; the renovated park was dedicated in 2011.
Saffold Dam
Along the Guadalupe River in Seguin, this dam sits within Max Starcke Park, a 227-acre city park with picnic pavilions, a walking trail, riverbank fishing, and a paddling trail on Lake Seguin.
San Antonio Missions National Historical Park
Texas' only UNESCO World Heritage Site links four 1700s mission communities, including Mission San José with its Rose Window and Mission Concepción, along the Mission Reach trail, which also runs to downtown San Antonio.
Mission Concepcion
Dedicated in 1755, the stone church here is one of the country's oldest remaining original stone churches and the least restored of San Antonio's colonial missions. Inside, four rooms still show colorful frescoes painted more than 250 years ago.
Mission San Juan Capistrano
Founded in 1716 in East Texas as Mission San José de los Nazonis, it was moved to the east bank of the San Antonio River in 1731 and renamed San Juan Capistrano. It's part of a UNESCO World Heritage Site.
Mission San Francisco de la Espada
Part of the San Antonio Missions UNESCO World Heritage Site and still an active parish, Espada shows off a three-bell stone chapel front and a double-arched 1745 aqueduct that carries its acequia over Piedras Creek.
Lake Casa Blanca International State Park
Set on a 1,680-acre reservoir in Laredo, minutes from the Mexican border, the park draws anglers after bass, crappie and catfish, along with swimmers, boaters and water-skiers. Trails, picnic areas and shoreline campsites fill the land side.
Monterrey Cathedral
Built over more than a century and finished with a baroque facade in 1800, Monterrey's cathedral faces the downtown Plaza de Armas. Its bell tower went up in the 1890s, and a 1940s mural by Ángel Zárraga decorates the apse.
Fundidora Park
For nearly a century this was the Fundidora steelworks; today it's a big public park with preserved industrial buildings, including a former blast furnace that now houses a steel museum with viewing platforms.
When you get to Santiago
About 40 minutes by car south of Monterrey, Santiago lies in the Sierra Madre Oriental between Cerro de la Silla and Cumbres de Monterrey National Park. It joined Mexico's Pueblos Mágicos program in 2006 and serves as the base for waterfalls, canyons and the reservoir at Presa de la Boca.

How we put this guide together
Wayro calculates the route from OpenStreetMap road data; mile numbers are positions along this route, not highway mile markers, and "from the route" distances are straight-line, so the real detour depends on access roads. Stops are chosen from parks, natural sites, museums, historic sites and attractions close to the route (roughly 2 to 7 miles depending on the type, farther for World Heritage sites): at least one strong stop for each stretch of the drive, then the best-known places nearest the road, with no more than five of one type, up to nine in all. Places that are closed, private or not open to visitors are removed. Place and city descriptions are written by the Wayro team from official park, museum, tourism and government websites and other published sources. Safety levels and entry rules were checked against the U.S. Department of State on September 29, 2026. Conditions change, so check the linked sources before you travel.
