Ask about this camp →U.S. Forest Service lists this as a developed campground. Expect marked sites, a fee station or a reservation, and the usual campground rules. The dispersed-camping freedom of the surrounding forest does not apply inside it. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.

From the Forest Service's own Motor Vehicle Use Map roads layer (EDW, Clearinghouse refresh Aug 30, 2026), straight-line from the pin to the nearest mapped segment. The nearest segment is not necessarily the way in, a maintenance level is the agency's class and not a report on today, and a road's season is the road's — it is not a campground order.

Coming out here — Flat Rock Extension Campground · Salmon-Challis National Forest · ID
- Surface water mapped nearby: USGS maps Yankee Fork as a perennial stream, under 0.1 mi from the pin (National Hydrography Dataset, data refreshed October 2022). Mapped as perennial is not the same as flowing today. Nobody has checked it for you. Filter or boil anything you drink.
- Ground slope around the pin: about 7.4% — gentle. Measured on USGS's 3DEP elevation model (1 m data here), sampled every 10 metres around the point. That is the hillside, not the ground under your wheels — a graded pullout or a bench a few metres across is too small to show up at that spacing, and nobody has checked this one for you.
- No rail line and no interstate or US route is mapped within 10 mi of the pin. Checked against the FRA/BTS North American Rail Network (data updated Jul 21, 2026) and the Census's TIGER/Line primary roads (TIGER/Line 2025, released Oct 2025). Both are national files and both are maps of what is built, not counts of what moves on it.
- Power: Dave carries his own — batteries or solar. A generator will run your rig and it is also the thing everybody camped near you can hear.
- Getting online: Dave recommends Starlink. He has had it since SpaceX introduced it, used it for four years living on the road, and it delivers as promised — several hundred nights out, and he can count on one hand the places he could not connect. The cable on his unit runs 150 feet, which is usually all it takes to find enough sky. Starlink → Referral link — Starlink pays Dave $100 in cash if you sign up through it, and that money funds this site and the next trip. It costs you nothing and does not change the recommendation.

Likely — The record is good enough to put a pin on, but thin in places. Treat the details as a starting point, not gospel.
How it was placed
Developed FEE campground (not free) - review | auto:usfs-fee 2026-08-20: US Forest Service developed campground, agency coordinates, agency states a fee. No dollar amount in the agency record -- expect a charge and confirm the current rate before you go. Not field-verified. | Fee 2026-08-22: the forest's own page contradicts itself -- its fee field reads $5 per night single site while the sentence directly below reads 'A $10.00/night fee is charged for overnight camping'. Carry enough for $10. No recreation.gov listing. Source: https://www.fs.usda.gov/r04/salmon-challis/recreation/flat-rock-extension-campground (page last updated July 1, 2026). || Water: Salmon-Challis National Forest's own site page for Flat Rock Extension Campground, https://www.fs.usda.gov/r04/salmon-challis/recreation/flat-rock-extension-campground (read 2026-08-24; page "Last updated" July 1, 2026), "Facility and Amenity Information > Water": "Potable water is not available at this site.". Corroborated by the USFS EDW Recreation Sites layer (apps.fs.usda.gov/arcx/rest/services/EDW/EDW_RecInfraRecreationSites_02/MapServer/0, re-queried live 2026-08-24 for SITE_ID 32288 / MANAGING_ORG 041302), WATER_AVAILABILITY = "No; drinking water is available at nearby campgrounds". Page "Seasons of Use": "6/1" -- that is the season of the SITE, not a statement about when the water is turned on. The parenthetical in the value is the page's own sentence, verified present on the live page at write time: "There are no hookups, drinking water is only available from nearby Flat Rock Campground." No natural water anywhere near this site is claimed to be potable. Agency record only -- not field-verified. Nightshift fire 1680 (Idaho batch 2).

On the agency's books. The land manager inventoried this site, so its existence is not in question — current conditions are. Nobody from here has camped it recently.
What we don’t know about Flat Rock Extension Campground
A land record can put you within a few meters of a spot. It cannot tell you any of this — so check it yourself, and treat anything below as the open question it is.
- Whether that MVUM road is the way in, and the last stretch beyond it
- How many rigs actually fit
- Cell coverage by carrier
- Current fire restrictions
- Whether any water here is drinkable
- Shade & wind exposure
- Noise and who else shows up
- Whether a listed EV charger works today, or the road miles to it
