Only at a few. About 12 of 63 sites have a clear gap in the trees for Starlink and 10 a partial one; most sit under tall trees. Satellite texting on a phone needs less open sky, but still works best from the most open spot you can find. This is our estimate from tree heights — check with the Starlink app's obstruction check when you arrive.

31 of 63 sites are flat, and 19 more have a gentle slope most RVs can level with blocks; 13 are steeper, better for tents. Sites that take RVs or trailers fit rigs up to 80 ft.

Yes. T-Mobile, Verizon and AT&T all report coverage at every site at Twiltley Branch Campground. That's the coverage each carrier reports to the FCC, not a measured signal, so under trees or below a ridge it can be weaker.

How we know Sources and limits
Shade, sun and Starlink are our estimates from Meta and the World Resources Institute’s canopy-height model (about 2 m pixels, from satellite imagery calibrated with space lidar; CC BY 4.0). From 2 m above each site we trace 72 lines out to 60 m and note the tallest tree in each direction. Shade counts trees overhead, the canopy within 30 m and how much of the afternoon sky is blocked. Sun counts how open the southern sky is. Starlink needs open sky above 35°, with the northern half counted twice because US dishes tilt north, and we keep the best spot within 8 m of the site’s post. The model sees tree heights only, not trunks, buildings or hills, so check with the Starlink app when you arrive.
Slope is the ground at each site’s post over about 4 m, from USGS 3DEP 1 m lidar: level under 2%, gentle to 4% (most rigs level on blocks), sloped to 8% (fine for a tent), steep beyond.
Cell coverage is from the FCC Broadband Data Collection (carrier filings as downloaded May 2026): each site is tested against each carrier’s modelled outdoor 4G/5G coverage. It is what the carriers report, not a measured signal.
Weather is NOAA’s 1991–2020 climate normals for the campground. Sites and facts are from Recreation.gov’s open data (July 2026). Map imagery: USGS The National Map.
From the campground’s Recreation.gov listing: “With four boat ramps and three designated swimming areas, there's plenty of ways to enjoy the lake shore. Many sites have electric hookups and there's a pay phone onsite. Pets are allowed on a six (6) foot or shorter leash. Okatibbee Lake boasts 4,000 acres of water surface in the Pascagoula River Basin. Extensive beaver flowages, stump beds and old creek channels provide abundant cover where anglers battle largemouth bass and crappie. Summers are hot and humid, with temperatures ranging from 70 to 98 degrees Fahrenheit.”
