Parcel 1 (139A-0-40-322.000) delivers 0.45 acres (19,695 sq ft) of partially wooded land with direct frontage on Highway 603 and Breaths Bayou access at the rear property line. Parcel 2 (139A-0-40-323.000) adds an additional 0.22 acres (9,512 sq ft) with the same highway presence and waterway access at the rear. Combined, the two parcels offer approximately 0.67 acres with a versatile footprint suited for residential development, a commercial build, or a long-hold waterfront investment. The tree coverage on both lots provides natural privacy and character -- the kind of mature canopy that takes decades to grow and can't be manufactured on a cleared lot. Highway 43 frontage means visibility and access, while Breaths Bayou at the rear connects to the broader waterway network feeding into Bayou Lacroix, the Jourdan River, and ultimately the Gulf of Mexico -- giving a future owner both road presence and a back door to the water. Bay St. Louis continues to attract buyers who understand what this stretch of the Mississippi Gulf Coast represents -- a genuine coastal lifestyle within an hour of New Orleans, minutes from historic downtown Bay St. Louis, and positioned in one of the fastest-growing communities on the Gulf South corridor. These parcels are being offered together. Buyers seeking maximum flexibility, combined acreage, and the rare pairing of highway frontage with rear waterway access should move quickly. ## Location - **Address:** 10862 Highway 603, Bay Saint Louis, MS 39520 - **County:** Hancock - **Coordinates:** 30.323472, -89.416809 - **Google Maps:** https://www.google.com/maps?q=30.323472,-89.416809 ## Virtual Tour & Media - **Video Tour:** https://www.propertypanorama.com/10862-Ms43-Bay-Saint-Louis-MS-39520/unbranded ## Listing Agent - **Name:** Douglas Adams · **License:** S57911 - **Brokerage:** Crescent Sothebys International Realty - **Broker Phone:** (228) 697-3714 - **Listing URL:** [View original listing](https://www.realtor.com/realestateandhomes-detail/10862-Highway-603_Bay-Saint-Louis_MS_39520_M99458-16260?f=listhub&s=MGCMLSMS&m=4144895&c=propsimple) ## Photos ![10862 Highway 603 - Photo 1](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f311550749r.jpg) ![10862 Highway 603 - Photo 2](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f2280882791r.jpg) ![10862 Highway 603 - Photo 3](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f794506975r.jpg) ![10862 Highway 603 - Photo 4](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f3143311701r.jpg) ![10862 Highway 603 - Photo 5](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f2617154735r.jpg) ![10862 Highway 603 - Photo 6](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f2890207185r.jpg) ![10862 Highway 603 - Photo 7](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f2919251318r.jpg) ![10862 Highway 603 - Photo 8](http://lh.rdcpix.com/0c4a915082e3e6e90e94167954a23375l-f3599978228r.jpg) --- **MLS#:** 4144895 | **Updated:** 2026-10-31 **Source:** listhub *Copyright © 2026 MLS United.
