The place
the agency’s own description · what’s there
In the agency’s own words
The Box Canyon Campground is situated on the canyon rim above the Henry's Fork of the Snake River. There are 16 single and 2 double units, each having tent and camper pads, fire rings, grills and picnic tables. Two of the single campsites are pull throughs. Campsites near the canyon rim are shaded by lodgepole pine and Douglas-fir. There are 2 vault toilets, water hydrants, and a bear-proof dumpster. The area is wheelchair accessible. This campground has several short trails that leave the Box Canyon Trail to access the Henry's Fork.

Nothing to book, just show up
One of 1,623 federal campgrounds where the site still goes to whoever pulls in first. Get there before noon on a summer weekend.
recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.
