The Insider's Guide to Living in Costa Bella (Lake Travis, Austin, TX 78734)

Costa Bella is one of the most coveted gated communities on Lake Travis. It is an intimate enclave of Mediterranean-style estates on large lots, and its biggest draw is access to the lake: many homes have boat slips, and the community has its own private marina. I have sold homes in Costa Bella and represented clients in nearby lake communities including Vineyard Bay, Lakeway and Arbolago, so I can help buyers compare their options on Lake Travis.

What You Are Actually Buying Into

A private community marina. The Costa Bella marina has about 72 boat slips and can accommodate boats up to about 50 feet, so residents can enjoy lake life even if their home is not on the water.

Lakeview clubhouse and amenities. A clubhouse overlooking Lake Travis, a resort-style pool, a fitness center and tennis and basketball courts.

Privacy and space. Large, wooded lots and a gated entrance give Costa Bella a quiet, established feel.

Local Insider Tips: What Only a Realtor Can Tell You

Ask about the boat slip. Not every home comes with a slip, and slip size matters. I always confirm whether a slip conveys with the home and what the marina fee is.

Water levels matter on Lake Travis. Marina location and water depth affect how usable a slip is in a drought year, so it is worth asking about before you buy.

Compare nearby lake communities. Costa Bella, Vineyard Bay, Arbolago and Lakeway each offer a different scale and price point on the water. I have worked in all of them and can help you compare.
