Warm Slough

12 ReviewsAdd Review

River floaters and anglers find direct access to Henry's Fork of the Snake River at Warm Slough, where multiple campsites spread along the water's edge near Rexburg. This free campground operates under seasonal restrictions, with overnight camping permitted only from October 1st through January 30th for up to 10 consecutive days.

The campground's layout extends along a dirt road system that parallels the slough, offering both drive-in and walk-in site options. Most sites include fire rings, and several feature picnic tables positioned to take advantage of the waterfront setting. Two pit toilets serve the area, though maintenance quality varies by season and location within the campground. Shauna & Steve H. notes "several great spots by the river" with established fire rings and tables.

Water activities dominate the recreation opportunities here. Campers launch tubes and small watercraft directly from the sites to float downstream, while fishing along the banks attracts those targeting the slough's resident fish populations. Wildlife sightings include moose and deer, particularly during early morning hours when mist rises from the water surface.

Access requires careful navigation, as GPS systems frequently provide incorrect directions to the actual campground entrance. The correct route follows Warm Slough Road off 4000 North, continuing past no-trespassing signs that apply to adjacent private property rather than the road itself. Cell service reaches the campground area, and campers can explore additional camping near Rexburg for extended stays beyond the 10-day limit.

The seasonal closure during summer months addresses overuse issues, making fall and winter the primary camping seasons when the area maintains a quieter atmosphere for those seeking riverside camping without fees.

We love this campground

We love camping at Warm Slough. Several great spots by the river. Several have fire rings and some have picnic tables. There are 2 pit toilets. This year they closed it for overnight camping in the summer due to misuse. However, camping is allowed during the fall and winter beginning October 1st to January 30th for a limit of 10 days. My kids love tubing down the Warm Slough River and my son likes fishing along the banks.

Tricky to Find but Worth It

This place was hard to find - I almost gave up. The GPS directions and coordinates on this app are both wrong. Take Warm Slough Rd off 4000 N. Ignore the no trespassing signs- they refer to the land on either side of the road. You can also search "Warm Slough Campground" in google maps. There is a smaller campground at the end of the road, and a larger one with pit toilets if you hang a right at the brown sign with the various camping rules.

Lots of options with fire rings and tables. Really nice and peaceful once you find it :-)

Good for the price($0)

As many free sites are it hasn’t been maintained or respected by those who use it. There’s trash all over and broken glass in the pit toilet. But there’s some picnic tables and fire pits and plenty of space.

Nice for a night

Pro tip: don’t try to find this location using Apple Maps. iOS will take you to the main road ands that’s it. Then you have to hunt for the dirt road that goes to Warm Slough. That road looks very much like private property. Google Maps will take straight to the actual site.

If you fish or want to float Henry’s Fork of the Snake River, this may be a good spot for multiple nights. It’s right on the water. Pretty. Multiple spots with fire pits, but well-spaced. We got the last spot on a Monday in Oct, but it didn’t feel crowded at all.

There are 2 pit toilets. The one at the front is truly disgusting. The one further in by the boat launch is clean, but no TP. Maybe Idaho Fish & Game consider October to be off-season and it would be better maintained in Summer.

We heard hunters close by, but they stopped by about 8:00pm. Otherwise, it was quiet and peaceful. The morning was beautiful - cold with mist coming off the river. For us, it was great for a one-night pit stop on a longer road trip.

Cool free spot

It’s nice and open, many campsites to choose from. There’s pit toilets, the main one is pretty dirty though. Overall it’s a really nice place not far from town either.

quiet and peaceful

We spent 2 nights here in between trips to Yellowstone and Tetons due to winter road closures. Great spot to hang out outside of Rexburg. Each site has a fire ring and plenty of privacy. Toilets are operating and clean. Right on the banks of the slough and there’s even a resident moose!

Good tent camping, good water access

Easily accessible. We camped in our tent, the roads were super easy to drive on. Great water access. Lots of wood for campfires. Yes cell phone service and it was free! Although the bathroom was very unclean.

My Go To

Can camp in tents, cars, or hammocks. Lots of spots near the rivers throughout the dirt road. Pretty popular for fire pits in the spring and summer. Can float the river as well. Sometimes see the occasional moose or dear.
