Overview
Lake Dunlap is a small, quiet residential community of roughly 1,900 people situated along the Guadalupe River in Guadalupe County, Texas, about 30 miles northeast of downtown San Antonio and just a few miles from New Braunfels. The community takes its name from Lake Dunlap itself — a narrow reservoir created by one of several low-head dams built on the Guadalupe River by Guadalupe-Blanco River Authority (GBRA) in the early 20th century.
The area is best understood as a lake-oriented neighborhood rather than a conventional tourist destination. Most visitors come for the water — fishing, kayaking, and leisure boating on the Guadalupe — or to pass through as part of a broader Hill Country or New Braunfels itinerary. The surrounding landscape is classic Texas Hill Country edge country: live oaks, cedar, rolling terrain, and a river corridor that stays noticeably cooler than the surrounding plains in summer.
Important context: In 2019, the Lake Dunlap dam failed, draining much of the lake. As of this writing, GBRA has been working through a lengthy process regarding the dam's future. Travelers interested in boating or full-lake conditions should verify the current status of the reservoir locally or through GBRA's official communications before planning a water-focused trip.
Before You Go
Dam and Water Level Status
The single most important pre-trip check for Lake Dunlap is confirming current water conditions. The 2019 dam failure significantly altered the lake's character, and restoration or dam-replacement timelines have shifted over the years. Check with GBRA (Guadalupe-Blanco River Authority) or local community sources for the latest information before assuming full boating access.
Visas and Entry
Lake Dunlap is in the United States. For entry requirements, visit TravelerPulse's Visas section and consult the official U.S. Customs and Border Protection website for current guidance specific to your nationality.
What to Pack
- Sun protection (hat, sunscreen, UV-protective clothing) — Texas sun is intense April through October
- Insect repellent, particularly if visiting near dusk along the river
- Water shoes if you plan to wade or launch a kayak
- Cash for small local purchases; verify card acceptance at any local vendor
Getting There
Lake Dunlap sits just off Interstate 35 in Guadalupe County, making it straightforwardly accessible by car. From San Antonio, the drive is roughly 30–35 miles northeast via I-35; from Austin, it is approximately 45–50 miles southwest on the same corridor. New Braunfels, the nearest sizable town, is only a few miles away.
The nearest major commercial airports are San Antonio International Airport (SAT) and Austin-Bergstrom International Airport (AUS). Both are within reasonable driving distance. There is no scheduled public transit or intercity bus service that serves Lake Dunlap directly; a personal vehicle or rideshare from New Braunfels is the practical option for most travelers.
Rideshare availability (Uber, Lyft) exists in this corridor but may be less reliable than in urban centers — verify availability at the time of your visit, especially for return trips.
Getting Around
Lake Dunlap is a small lakeside community with no local public transportation. A personal vehicle is effectively required to get around. Roads in and around the community are a mix of county roads and residential streets; navigation apps work reliably in this area.
For those interested in the river corridor, some sections of the Guadalupe are accessible by non-motorized watercraft such as kayaks and canoes — again, verify current access points and water conditions before arrival, as these can change depending on dam and flow status.
Things to See & Do
On and Near the Water
Historically, Lake Dunlap's primary draws have been fishing (largemouth bass, catfish, and other Guadalupe River species are common), recreational boating, and casual paddling. Verify current access and conditions given the ongoing dam situation before planning water activities.
The Guadalupe River corridor more broadly — including sections near New Braunfels — offers well-established tubing, kayaking, and swimming. New Braunfels outfitters rent tubes and kayaks for Guadalupe and Comal river floats, which are a very short drive from Lake Dunlap.
Natural Surroundings
The general area features walking along the river and quiet country roads. Birdwatching can be rewarding along the river corridor, particularly during spring and fall migration.
Nearby Attractions
Most structured attractions and dining require a short drive to New Braunfels or further into the Texas Hill Country. Consider combining a Lake Dunlap stop with visits to Landa Park in New Braunfels, Natural Bridge Caverns, or Gruene Historic District — all within a short drive (see Nearby section).
Food & Drink
Lake Dunlap itself has no significant restaurant or bar district — this is a residential community. Travelers will find their dining options in nearby New Braunfels, which has a well-developed food scene ranging from traditional German Texas restaurants (the area has deep German immigrant heritage) to Tex-Mex, barbecue, and contemporary dining.
Gruene, a historic district just a few miles away, has a small concentration of well-regarded restaurants and the famous Gruene Hall venue. Verify current hours and availability locally, as small Texas towns see variable seasonal hours.
Practical Information
Emergency Services
For any emergency in the United States, dial 911. Guadalupe County Sheriff's Office serves the unincorporated areas around Lake Dunlap. The nearest hospital facilities are in New Braunfels and San Antonio — verify the nearest urgent care or emergency room location before your trip.
Connectivity
Cell coverage is generally available in the Lake Dunlap area on major U.S. carriers, though signal can be inconsistent close to the river or in lower terrain. Download offline maps before arrival.
Weather
Summers (June–August) are hot, frequently exceeding 95°F (35°C). Spring and fall offer the most comfortable conditions. Winters are mild but occasional cold fronts can bring sharp temperature drops. The Guadalupe River corridor can experience flash flooding — monitor local weather alerts, especially during spring storm season.
Safety
Lake Dunlap is a quiet residential community and does not present unusual safety concerns for visitors. Standard travel common sense applies: secure valuables in your vehicle, be aware of your surroundings at boat launches or remote river access points, and inform someone of your plans if heading out on the water.
Flash flooding is the most significant natural hazard in this part of Texas. The Guadalupe River can rise rapidly after heavy rain upstream. Check National Weather Service forecasts and heed any flood warnings — do not attempt to cross flooded roads or waterways. The Texas "Turn Around Don't Drown" campaign exists for good reason in river-corridor communities like this one.
