Grand Teton’s own camping page names 14 free campsites, and none of them are in the park. They sit along Grassy Lake Road in the John D. Rockefeller, Jr. Memorial Parkway, the strip of Park Service land between Grand Teton and Yellowstone.
Here is the wording, from the park’s camping page, read August 26, 2026. Grassy Lake Road “has 14 designated campsites in eight areas along the road, free, first-come-first-served sites that are accessible once the road opens in mid-June.” The sites are “primitive with no water but do include shared toilets, bear boxes, and trash facilities.”
The conditions come attached in the same paragraph: camp only in designated sites, store food properly, park only in parking areas, no discharging of firearms, follow leave no trace. Fourteen sites across eight areas means most areas hold one or two vehicles. This is not an overflow lot.
Inside the park, the rule is the opposite
The same page is blunt about the boundary you are working around. “Car camping or sleeping overnight in vehicles is NOT allowed in park pullouts, parking areas, picnic grounds, or any place other than a designated campground.” Overnight parking at a trailhead is permitted only with a backcountry permit. And separately: “Camping is not permitted within the park along roadsides, at overlooks, or parking areas. Doubling up in campsites is prohibited and there are no overflow facilities.”
So the park has 1,000 sites across seven campgrounds, all reservation-only through Recreation.gov, bookable up to six months out. If those are full, the park’s own advice is to leave: the Parkway, national forest, Yellowstone, or a private campground. There is no legal fallback inside the boundary.
Stay limits, from the same page: seven days per person at Jenny Lake, 14 days at the other campgrounds, and no more than 30 days in the park per year. That annual number is parkwide. Moving between campgrounds does not reset it.
The catch worth knowing
That page carries a “Last updated: December 27, 2022” stamp. It is still the park’s live camping page and it is the only official source we found for the Grassy Lake sites, but a four-year-old page is not a promise about this week. Site counts, road status and closures all move.
We have not verified a current opening or closing date for Grassy Lake Road beyond the page’s “mid-June,” and we are not going to guess at one. It is a rough dirt road, and the Park Service does not publish a fall closing date on this page.
What to do
Call Grand Teton at 307-739-3399 before you count on a Grassy Lake site, and ask two things: whether the road is open, and whether all 14 sites are still designated. Carry all your water, because the page says there is none.
Then read the sign at the site. The posted sign and whoever manages that road beat any website, this one included.
