See the tree canopy in RoamWill Starlink work at Guilford Lake State Park Campground?
At some sites. About 11 of 40 sites have a clear gap in the trees for Starlink and 14 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.

13 of 40 sites are flat, and 16 more have a gentle slope most RVs can level with blocks; 11 are steeper, better for tents.

Yes. T-Mobile, Verizon and AT&T all report coverage at every site at Guilford Lake State Park 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 Guilford Lake State Park Campground?
October. In a typical year the leaves around Guilford Lake State Park Campground are at their best in late October into early November, though any one fall can run a week or two early or late.

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 — where each one is, its number and its type — are from the agency’s own campsite GIS feed: Ohio DNR’s state park camping-units map (as of August 2026); the park is placed with the USGS Protected Areas Database (PAD-US) and named as the agency names it.
