Jenny Lake Campground

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. Photos: Recreation.gov.

From the campground’s Recreation.gov listing: “Jenny Lake Campground is a tent-only campground. Trailers, campers, pop ups and ALL towables are not permitted. Each campsite includes a compact gravel parking space for ONE VEHICLE NO LARGER THAN 8 FEET HIGH AND 14 FEET LONG, a tent pad, a picnic table, a fire pit with metal fire grate, bear-proof food storage lockers, and access to nearby water spigots, flush toilets, and two token-operated showers. Only two tents are permitted per site. ADA Access: Three campsites are ADA compliant, and feature accessible picnic tables, leveled sites, and leveled pathways to accessible restrooms and payphone. One coin-operated shower is also ADA accessible. Jenny Lake Campground is situated within short walking distance of Jenny Lake and right along the Grand Teton National Park bike path. The campground straddles a glacial moraine covered with an open forest of lodgepole pine, subalpine fir and Douglas fir. Across the lake, Teewinot Mountain, Cascade Canyon and Mount St. John dominate the landscape. The Jenny Lake area is home to black and grizzly bears, moose, deer, and other large animals.”
