Questions
Which sites at Rainbow Point Campground are the shadiest?
Nearly all of them. 81 of 83 sites at Rainbow Point Campground have good shade from the trees, including from the hot afternoon sun.
See the tree canopy in RoamWhich sites at Rainbow Point Campground get the most sun?

See the tree canopy in RoamWill Starlink work at Rainbow Point Campground?
Only at a few. About 2 of 83 sites have a clear gap in the trees for Starlink and 27 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.

55 of 83 sites are flat, and 25 more have a gentle slope most RVs can level with blocks; 3 are steeper, better for tents.

Yes. T-Mobile, Verizon and AT&T all report coverage at every site at Rainbow Point 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: “The campground offers several single-family campsites, many of which have electric hookups. Sites are equipped with a picnic table and campfire ring. Vault toilets and drinking water are provided. Firewood is available for purchase within the campground. Hebgen Lake sits on the Madison River, at an elevation of 6,240 feet. The lake covers 21 square miles and has 65 miles of shoreline. Rainbow Point is situated on Rainbow Bay, among a dense forest of lodgepole pine. A variety of waterfowl is often spotted in the area, including sandhill cranes, herons, Western grebes, white pelicans, osprey, Canada geese, mallards, wood ducks, loons and bald and golden eagles. Bison, deer and moose are frequently seen as well.”
