Serene Hills is a 339-home community in Bee Cave where roughly 75 percent of the land was left as preserved green space. That means the neighborhood has more acres of open terrain than residential lots. That ratio is not typical for the price point. Most Bee Cave and Lakeway communities maximize lot yield. Serene Hills went the other direction, and the result is houses that sit in the landscape rather than covering it.

The community is in Bee Cave within the 78738 zip code, along Bee Cave Parkway between Highway 71 and Hamilton Pool Road. Downtown Austin is roughly 25 minutes east via Highway 71 to MoPac. The Bee Cave commercial corridor with H-E-B and Hill Country Galleria is about five minutes away. Lakeway is approximately ten minutes west. Falconhead borders to the south and Sweetwater to the north and east.

Housing was built primarily between 2014 and 2020. Contemporary Hill Country architecture dominates at roughly 40 percent, with native stone, stucco, metal roof accents, and oversized windows that take advantage of the green space views. Modern Farmhouse designs account for about 25 percent. Mediterranean influences appear in about 15 percent. Lot sizes range from a quarter acre to over half an acre on perimeter lots backing to preserved land. Pricing runs from the high $700s to over $2 million. The active market for a four-bedroom falls between $1 million and $1.6 million.

Lake Travis ISD serves Serene Hills. Students attend Bee Cave Elementary, Lake Travis Middle, and Lake Travis High. The district is well-regarded for academics, athletics, and extracurriculars. The tax base from Bee Cave and Lakeway commercial development supports teacher compensation and facilities. The elementary campus is close enough that the morning drop-off is brief, a practical detail that matters more to daily life than rankings.

With 339 homes, residents know neighbors by name. That is not a figure of speech. Community events, the pool, and trails create enough recurring contact for relationships to form naturally. Internal trails connect to Bee Cave Park Loop for longer outings. For dining, Tadashi serves Japanese cuisine with quality ingredients. Cafe Blue offers polished seafood. SP Brazilian handles special occasions. CARVE American Grille brings straightforward steaks and cocktails. The Grove Wine Bar works for quieter weeknights. Restaurant density in Bee Cave has reached the point where residents eat out several nights without repeating.

Compared to Rough Hollow, which is four times the size with a marina, Serene Hills offers a quieter experience with more breathing room and tighter social fabric. Compared to Sweetwater nearby, Serene Hills is smaller with more preserved natural terrain. Sweetwater offers more resort-style pools and a wider price range. Compared to Falconhead with its golf course, Serene Hills replaces golf with green space. No golf course, no marina, no lazy river. What it has is land that was left alone.

Serene Hills is for buyers who have looked at the large master-planned communities and decided they want something quieter. If 339 homes is the right scale, if you would rather look at open Hill Country than a roofline, and if Lake Travis ISD and a 25-minute commute check the practical boxes, this delivers. It works for families with young children who want kids growing up together, and couples wanting Bee Cave without the density. The green space is the product. Everything else is built around preserving it.
