Recreation
Great opportunities for hiking, fishing, scenic driving and wildlife viewing are available around the campground. The North Fork of the Shoshone River is a popular fly-fishing location for rainbow and Yellowstone cutthroat trout. The nearby Pahaska Trail provides access into the North Absaroka Wilderness Area.
Facilities
The campground offers family campsites for hard-sided camp trailers and RVs. Some sites overlook the river. Each site is equipped with a table, campfire ring and food storage locker. Vault toilets, hand-pumped drinking water (two spigots, one spigot is accessibiliy compliant) and trash collection are provided. Campers may gather firewood in the area.
Natural Features
The campground is situated along the North Fork of the Shoshone River and has beautiful views of the surrounding mountains. A forest of lodgepole pine covers the campground, which sits at an elevation of 6,700 feet. A wide variety of wildlife lives in the area. Visitors often glimpse grizzly bears, deer, elk, bison, moose, fox, coyotes and bald eagles.
Nearby Attractions

What you actually pay
Derived by CAMPANAC: the agency’s published rates for this season, $20–$40 a night, plus one $8 recreation.gov reservation fee for the booking. A weekend here means Friday and Saturday night, booked once. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.
Who keeps the booking fee
The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

The price is derived by CAMPANAC, not published per site: the per-night rate this campground publishes for each site’s own site type. 21 of the 21 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.
