See the tree canopy in RoamWill Starlink work at Aux Arc Campground?
At some sites. About 25 of 85 sites have a clear gap in the trees for Starlink and 13 a partial one; the rest sit under 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.
See the tree canopy in RoamWhich sites at Aux Arc Campground are the most level?
56 of 85 sites are flat, and 24 more have a gentle slope most RVs can level with blocks; 5 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 Aux Arc 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.
See the coverage map in RoamWhen is the best time to see fall color at Aux Arc Campground?
October. In a typical year the leaves around Aux Arc Campground are at their best in mid to late October, though any one fall can run a week or two early or late. Much of the forest here stays green, so expect color in patches. Roam’s fall foliage map shows how far the color has come this week, free every September through November.

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.
Fall color is the typical peak from NASA’s MODIS satellite record of when leaves change (2001–2023), limited to deciduous and mixed forest with USGS land cover (NLCD), calibrated to the USA National Phenology Network’s ground reports of colored leaves (CC BY 4.0). It is an average of many autumns, so the page gives a window, not a date.
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. Photos: Recreation.gov.
From the campground’s Recreation.gov listing: “Aux Arc Campground offers spacious, shady campsites with electric and water hookups. Three picnic shelters, with electricity, can be reserved as well. Additional amenities include a dump station, two playgrounds, hot showers and a boat ramp. Ozark Lake extends 36 miles along the Arkansas River. The shoreline of the lake varies from steep bluffs and tree-lined banks to open farm lands and level fields.”
