Mt Sharp Airpark Wimberley: A Brand New Fly-In Community in the Texas Hill Country

Mt Sharp Airpark (TT35) is a brand new fly-in community four miles north of Wimberley, built around a 4,650 foot concrete runway with a 1.5 acre fishing lake, an 80 by 100 foot community hangar, and roads you can taxi an airplane down right to your own front door. The FAA only activated the field in September 2025, which makes this one of the newest residential airparks in all of Texas. So if you have been quietly stalking airpark listings waiting for something fresh to pop up in the Hill Country (I see you, I am one of you), this is the new kid on the block.

According to AirNav, the field sits at roughly 1,111 feet MSL with Runway 12/30 in good condition, concrete surface, runway edge lights, and it is privately owned by the Mount Sharp Airpark Owners Association. Permission required prior to landing, no tower, CTAF on 122.975. That is the spec sheet. But the spec sheet never tells you whether you actually want to live somewhere, so lets talk about that part, pilot to pilot and broker to buyer.

Where Mt Sharp Airpark Sits in the Hill Country

Location is the whole ballgame with airparks, and this one is sitting in a pretty sweet spot. You are four miles north of Wimberley proper, which puts you about 19 minutes and 14 miles from Dripping Springs, roughly 23 minutes from San Marcos down RM 12, and about 45 minutes south of Austin depending on how the traffic gods feel that day.

Here is the thing about that Wimberley address though. Mount Sharp Road is the same road that runs to Jacob’s Well Natural Area, which is one of the most beautiful spring-fed swimming holes in Central Texas. So you are not out in the middle of nowhere staring at a runway and a fence line. You are in real Hill Country, cedar and live oak and limestone, the kind of land people drive an hour from Austin just to spend a Saturday in. And you get to fly home to it.

For my buyers who work in Austin but are tired of Austin (a category that grows every single year right), this geography is the sweet spot. Close enough to get to the airport, the airport, or a meeting downtown. Far enough that your view is hills and sky instead of your neighbor’s second story.

The Airstrip: What You Are Actually Flying Into

Lets walk through the runway, because this is where a lot of airpark dreams meet reality.

Runway 12/30 is listed by the FAA at 4,650 feet long and 60 feet wide, concrete, in good condition. The developer markets it as 4,700 feet, which is close enough that we are splitting hairs, but I always tell people to plan off the FAA number, not the brochure number. There are displaced thresholds, 150 feet on the 12 end and 200 feet on the 30 end, so your effective landing distance is a touch shorter than the full length. Left traffic for Runway 12, right traffic for Runway 30. Runway edge lights mean you can come home after dark.

That 4,650 feet of concrete is genuinely a lot of runway for a residential airpark. For comparison, plenty of Hill Country strips are 2,800 feet of grass that turn into a swamp after a good rain. Concrete that long means you are not just talking about Cubs and 172s. A lot of high-performance singles and turboprops can operate here comfortably, and the community hangar even advertises Jet fuel alongside AvGas, which tells you the developers are thinking about turbine traffic.

But here is the honest part, the part most listing copy will not tell you. There are no published instrument approaches at TT35. None. It is a VFR field. So when a cold front parks an 800 foot ceiling over the Hill Country for two days in January, you are not shooting an approach down to minimums and taxiing to your hangar. You are sitting at San Marcos or Austin Executive renting a car. If you fly hard IFR for business and getting home in the soup is non-negotiable, this is the single most important thing to weigh. My writeup on Threshold Ranch down in Boerne covers a field that does have published approaches, and the difference between the two communities really comes down to exactly this question.

Now, lets be fair. Most pilots are not flying 150 hours a year of actual instrument time. If you are a VFR pilot, or you fly IFR but you are flexible about your travel days, a VFR-only field is not a dealbreaker at all. It just needs to be a decision you make on purpose instead of a surprise you discover in February.

Density altitude is the other thing I would plan for. Field elevation is around 1,111 feet, which is not high. But this is the Hill Country in July, and when it is 100 degrees out your density altitude is going to climb well past 3,500 feet. Run your hot-and-heavy takeoff numbers before you buy, not your standard-day sea-level fantasy numbers. The good news is 4,650 feet of concrete gives you margin that a short grass strip never will. Plan your summer departures for the cool of the morning and you will be fine, no big deal right.

Living There: Hangar Homes, Acreage, and a Fishing Lake

Ok this is the part I actually get excited about, because Mt Sharp is not just a strip with houses bolted on. It was designed as a community first.

The whole neighborhood is laid out with ribbon-curb asphalt roads, which is a fancy way of saying the roads are built so you can taxi your airplane from the runway right up to your hangar at home. That is the entire point of airpark living and a lot of older parks did it badly. Doing it right from day one, in a community activated in 2025, is a real advantage.

Then there is the stuff that has nothing to do with airplanes. A 1.5 acre community lake stocked for fishing and kayaking. A spring-fed creek with a community area along it. About two miles of running trails. Underground power, which if you have ever lived in the Hill Country during an ice storm you understand is not a small thing (we lost power for the better part of a week in 2021 and I still think about it every time the forecast says “wintry mix”). And an 80 by 100 foot community hangar with overnight guest parking, a lounge, a conference room, and a workout area, plus the fuel.

Lots run large here, generally from a couple acres on the small end up to dramatically bigger parcels, so you have room for a real hangar home, a shop, a pool, whatever your version of the dream is. This is acreage living, not a subdivision with a taxiway. You are going to be on a well and a septic system, which is completely normal for this part of Wimberley and Dripping Springs, but it is something a buyer coming from the city needs to budget for and inspect. More on that in a second.

If you want to picture the lifestyle, think coffee on the porch with a view of your airplane and the hills, then a kayak on the lake in the evening, and the option to be wheels-up to anywhere in Texas inside of a few minutes whenever the mood strikes. As somebody who has admitted on camera that my idea of a perfect morning is coffee on a balcony, I get the appeal in my bones.

Who Mt Sharp Airpark Is Actually For

Lets be real about the fit, because airparks are not for everybody and pretending otherwise does nobody any favors.

This community makes sense for:

• The VFR or flexible-IFR pilot who flies a single or a turboprop and wants a real concrete runway, not a grass strip
• The buyer who wants genuine Hill Country acreage with a well, a septic, and elbow room, not a tight subdivision
• The Austin or San Marcos professional who is happy to trade a 45 minute drive for hills, sky, and a hangar in the backyard
• The early adopter who likes the idea of getting in on a brand new community while lots are still available and choices are still open

It makes less sense for the hard-IFR business flyer who absolutely has to get home in low weather, simply because there are no instrument approaches. And it makes less sense for somebody who wants to be ten minutes from a grocery store and a Whole Foods. Wimberley is wonderful, but it is a small Hill Country town, not a suburb. That is a feature for most airpark buyers and a bug for a few. Know which one you are.

The Real Estate Angle: What a Buyer Should Check

Here is where being a pilot AND a broker actually earns its keep, because buying into an airpark is not like buying a normal house and the due diligence list is different.

First, the airfield ownership. TT35 is owned by the Mount Sharp Airpark Owners Association, and “permission required prior to landing” means there is a structure governing who can use the runway and how. Read the association documents before you fall in love. Understand the dues, the rules, the maintenance reserve for that concrete runway, and what happens to the airport rights if you ever sell. The runway is the single most valuable shared asset in the whole community and you want to know exactly how it is governed.

Second, the well and septic. This is rural Hill Country. You are almost certainly on a private well and an on-site septic system. Get the well flow tested, get the septic inspected, and understand the water situation in your specific spot, because groundwater can vary a lot across the Wimberley area. This is normal and manageable, it just is not something a city buyer is used to thinking about.

Third, connectivity. If you work from home (and a lot of airpark buyers do), confirm what internet you can actually get. Hill Country broadband has improved a ton but it is still worth verifying line by line rather than assuming.

Fourth, because this is a newer community, look hard at what is built versus what is planned. New airparks are a chance to get a great lot, but you are also buying into a vision that is still filling in. Ask what the build-out timeline looks like, how many lots have sold, and who your neighbors are going to be.

Brand new airparks do not come along often, especially not ones with concrete this long in a location this good. Scarcity is real here. I wrote a whole piece on how Texas has more residential airparks than any other state, and even with all of them, the supply of genuinely new, well-built, long-concrete options near Austin is tiny. That scarcity is a big part of the value story. It is also why you do not want to rush the due diligence just because inventory feels urgent. Kahneman’s whole thing in Thinking Fast and Slow is that we make our worst decisions when we feel rushed and let the gut take over, and a runway home is exactly the kind of purchase where you want the slow, careful part of your brain in the pilot seat.

If you are new to all of this, my complete guide to airpark living walks through everything from hangar home construction to how runway rights work, and it is the place I would start before you tour anything.

Thinking About Mt Sharp or Another Hill Country Airpark?

I am a broker and a pilot, which is a combination that does not come around very often. That means I can talk crosswind components and comparable sales in the same conversation, and when you are buying into an airpark that is exactly the combination you want on your side of the table.

Mt Sharp sits right in the heart of the country I know best, the Hill Country west and south of Austin. At Neuhaus Realty Group, we work this market every day, from standard subdivisions to properties with hangars and taxiways. If you want a more developed and established option to compare against, take a look at my profiles of Lakeway Airpark and Lago Vista and Rusty Allen Airport over on Lake Travis. Different communities, different tradeoffs, same flying-home-to-the-Hill-Country dream.

Whether you are flying a Cub or a TBM, lets figure out where you belong. Reach out to Ed Neuhaus or get in touch with our team, and we will talk it through. Be safe, be good, and keep the shiny side up.
