The Hill Country's acreage belt, hiding in plain sight north of San Antonio
Spring Branch is an unincorporated Hill Country community in Comal County, Texas (ZIP 78070), spread along the US-281 and Hwy 46 corridor with roughly 20,600 residents. It's defined by acreage homesites, Canyon Lake and Guadalupe River access, and the A-rated Smithson Valley schools of Comal ISD — country space within 30–45 minutes of San Antonio and New Braunfels.
Settled by German farmers in 1852 along a spring-fed creek feeding the Guadalupe, Spring Branch has never been a downtown-and-a-square kind of town. The tiny municipality that incorporated in 2015 holds only a few hundred people; the Spring Branch that matters to buyers is the wider 78070 area — thousands of households spread across ranch land and lake-country subdivisions.
The anchor isn't an employer — it's the land and the schools. Comal ISD's Smithson Valley cluster is the single biggest reason families choose this stretch of western Comal County, and Canyon Lake plus the Guadalupe River give the area a recreational identity most suburbs can't match.
Growth here is real but rides on the broader Bulverde/Spring Branch corridor, where local economic-development figures project more than 20,000 new homes over roughly 5–10 years as buyers push north on US-281 chasing acreage they can't find closer to San Antonio.
Three buyers dominate: relocating families targeting Smithson Valley schools; move-down and lock-and-leave buyers who want Hill Country space without a Fredericksburg price tag; and lake-and-river buyers chasing Canyon Lake access, weekend places, and land.
1 · Water & septic. Most of 78070 is well-and-septic, not city utilities. Confirm the well, the septic type, and who maintains the road before you fall for the view.
2 · School section. It's Comal ISD across the core, but big subdivisions like Mystic Shores span attendance lines. Verify the exact campus at the address, not the subdivision name.
3 · Tax overlays. County + Comal ISD is the ~1.34% base. Specific subdivisions add an ESD, MUD, PID, or WCID — check the parcel's actual rate with the Comal County Tax Assessor.
Spring Branch is an ownership market first. Rental inventory is thin and skews to single-family homes rather than apartments, so renting long-term here often means competing for the same houses buyers want. The 78070 median sat around $449,000 in mid-2026, down from a 2026 peak — a cooling worth watching, not a collapse.
Because so much of the area is acreage and septic/well rather than city services, the "wrong part of town" mistake here is usually about land and utilities, not blocks. Confirm what you're actually buying before you fall for the view. Start with the guides below.
Where to Live
Mystic Shores
The area's flagship master-planned community, wrapped between the Guadalupe River and Canyon Lake's north shore. Gated and non-gated sections, 1–20 acre tracts, community pool and boat ramp. Often addressed via FM 306 / Canyon Lake — confirm the exact campus by section, as the far reaches shift attendance.
River Crossing
Established golf-course community off Hwy 46 with mature trees and a country-club core. More amenity-driven and less raw-land than the acreage tracts — a fit for buyers who want Hill Country setting without a ranch to manage.
Creekwood Ranches & Lantana Ridge
Larger-tract, low-density subdivisions for buyers whose priority is privacy and space — multi-acre homesites, mature oaks, and room between neighbors. Utilities are typically well and septic; verify both before you offer.
Rockwall Ranch
Gated 1–2 acre estate homesites with underground utilities on the New Braunfels-facing edge of the area, explicitly zoned to Comal ISD schools. Popular with buyers who want a build lot without a build deadline.
The Reference Desk
1 · An ownership market on acreage. The greater Spring Branch area (ZIP 78070) is unincorporated Comal County — roughly 20,600 residents spread across ranch tracts and lake-country subdivisions rather than a dense town grid. Inventory skews toward single-family homes on larger lots, much of it well-and-septic rather than city-serviced. Rental supply is thin, so long-term renting usually means competing for the same houses buyers want.
Source. Redfin put the 78070 median sale price at $449,398 for June 2026, down 15.6% year over year. That decline measures against an inflated 2026 peak near $620K, not a structural collapse — the median is volatile in a low-transaction, acreage-heavy ZIP, so verify at the address.
2 · What moves price here. Acreage, lake or river access, and gated versus open all swing value more than a street address does. A one-acre interior lot and a Guadalupe-frontage tract in the same subdivision price on entirely different curves. Land, water, and utilities — not blocks — are the variables that matter.
3 · The Smithson Valley premium. The single biggest non-land driver is schools. Homes zoned to the A-rated Smithson Valley cluster (Comal ISD) carry a relocation premium, and it is the first thing out-of-area families ask about. Confirm the exact campus at the address — big subdivisions here span attendance lines.
Typical housing stock. Master-planned lake communities like Mystic Shores, golf-course and gated sections like River Crossing and Rockwall Ranch, and larger-tract acreage subdivisions — most on well and septic. For a price-point view, see What $400K buys you in the Texas Hill Country.

The two arteries are US-281 (north–south) and Hwy 46 (east–west); the 281/46 junction is the area's commercial hub. This is car-dependent country — no rail, no fixed-route transit, ride-hail is thin. Budget for distance to everything.
Walk-in and freestanding-ER coverage clusters at the 281/46 node. For a full-service hospital — CHRISTUS or Resolute in New Braunfels, or the San Antonio systems — plan on a 25–40 minute drive.
The recently expanded ~140,000 sq ft H-E-B plus! at 20725 Hwy 46 W anchors local shopping. Big-box and specialty retail sit in Bulverde to the south or New Braunfels to the east.
There is no municipal utility — every service is by private company or cooperative, and the provider depends on the parcel. Electric is typically Pedernales Electric Cooperative (PEC) on the Hill Country/US-281 side or GVEC toward the Seguin/southeast side; confirm at the meter. Internet is largely GVTC fiber (covering most of the ZIP, up to 1 Gbps), with satellite filling rural gaps. Most homes are on well and septic, not central water/sewer — a defining feature of the area.
Unincorporated: trash is private-hauler contract (Republic and others), not a city route. Propane is common for heating and cooking off the gas main. Budget these as separate line items a city buyer wouldn't expect.
Dining is corridor-based rather than a downtown row — a mix of Hill Country cafes, BBQ, and lake-adjacent spots along US-281 and Hwy 46, plus chains near the 281/46 node (Panera sits beside the Texas MedClinic). For a broader restaurant scene, Gruene and downtown New Braunfels are ~25 minutes east and Bulverde is closer. Verify hours seasonally — river-and-lake traffic swings demand.
Rural acreage means room for animals and frequent white-tailed deer — fence and landscape accordingly. Vet and boarding services cluster around Bulverde and the 281/46 corridor, with emergency vet care in San Antonio.
As unincorporated territory, Spring Branch is governed by Comal County, not a city hall. Permits, septic (OSSF) authorizations, and floodplain review run through Comal County offices in New Braunfels; property records and valuations are at the Comal Appraisal District. New Texas residents transfer registration and license within 90 days through the Comal County Tax Assessor.
No city property tax for unincorporated parcels: the base is Comal County (0.2690) + Comal ISD (1.0748) ≈ 1.34 per $100 (2025). Specific subdivisions may add an ESD, MUD, PID, or WCID — verify the parcel's actual rate with the Comal County Tax Assessor.
Spring Branch trades a town identity for a landscape one. There is no historic square or festival calendar here — the draw is water, land, and quiet, wrapped between Canyon Lake and the Guadalupe River in the limestone hills of northern Comal County. What you get is space and access, not walkability.
Canyon Lake access
A U.S. Army Corps of Engineers reservoir on the Guadalupe, ~8,200 surface acres with roughly 80 miles of shoreline and eight public parks. Boating, swim beaches, fishing for largemouth, striped and smallmouth bass. Water rights are held by the GBRA; monitor lake level before you launch.
The Guadalupe River
The river runs through the area above the lake — mean flow at the Spring Branch gauge is about 353 cfs. Tubing, paddling, and fishing under the cypress. Nichol's Landing, a primitive WORD riverfront park in Spring Branch, sits on two Texas Paddling Trails. For cold-water angling, see Guadalupe River Trout Fishing.
Guadalupe River State Park
~1,938 acres straddling Comal and Kendall counties near Bulverde, ~15 minutes out. Four miles of river frontage for swimming, tubing, and fishing, plus hiking, birding, and camping across the Hill Country terrain.
Acreage & the night sky
Multi-acre homesites, oaks, and low density are the point. Away from city glare, the star visibility is a genuine amenity — and the wildlife (deer, especially) is a daily fact of life to plan your fencing and garden around.
Wineries & Hill Country drives
The US-281 corridor threads toward the Texas Hill Country wine trail and toward Gruene's dance-hall scene ~25 minutes east. Weekend country without leaving the county, plus easy reach to Blanco, Boerne, and Wimberley.
Smithson Valley country
Friday-night football and school identity anchor the community's social life the way a downtown would elsewhere. The A-rated Smithson Valley campuses are as much a gathering point as any main street.
Spring Branch draws three buyer types: families targeting the A-rated Smithson Valley schools; lock-and-leave and move-down buyers who want Hill Country acreage without a Fredericksburg price; and lake-and-river buyers chasing Canyon Lake access, weekend places, and land.
