Big Nelson Complex

The USDA Forest Service manages Big Nelson Complex as a compact lakeside campground with just four to six sites near Ovando. Most campers park in a central area and walk down stairs to reach their sites, though site 3 allows drive-up access. Sites 4, 5, and 6 sit closest to the water, with site 4 offering minimal tent space while sites 5 and 6 provide more room for camping gear.

The campground includes one vault toilet, picnic tables, and metal fire rings at each site. A gradual boat launch provides lake access for small watercraft. Campers must bring their own water and pack out all trash, as this operates as a dry campground with no water hookups or garbage service. Browns Lake sits less than 10 miles southwest for additional fishing access options.

Big Nelson not big no no no it is small very small.

Big Nelson Campground is anything but big. This is a tiny cramped campground. I found 6 campsites, but the Forest Service website list this campground as having four. With the exception of site three, all the other sites require you to park in a parking area. Site 3 was the first site I noticed on arriving at the campground and was located to the left of the parking area. Sites 4, 5 and 6 require parking in the parking area and walking down a set of stairs to access. Sites 4, 5, and 6 can only be accessed from the stairs, driving down the road to the boat launch will only get you to the boat launch. Site 4 is on the left at the bottom of the stairs. Site 4 is tiny, it is a picnic table next to a metal fire ring, if you want to pitch a tent at site four you would need to do it next to the fire ring and skip making a fire or pitch it in a small flat area above the picnic table near the parking area on the opposite side of the fence. Site four really doesn't have much room for a tent. Sites 5 and 6 are fairly roomy, especially when compared to site 4. Site 5 is on the right side of the stairs, plenty of room for a tent, nice view of the lake and has a metal fire ring and picnic table. Site 6 can be reached by walking through site 5 or from the boat launch road. You could unload your gear at site 6 right from your car, but would can not park next to site 6, you will need to drive back up to the camping area. Site 6 has plenty of room for a tent and also has a picnic table and metal fire ring. The campground has one small vault toilet and is at the beginning of the road to the boat ramp. The boat ramp isn't really a ramp, but the shore of the lake with a gradual entrance in to the water. Campsite 2 I found as I was leaving the area, it is just past the vault toilet as you leave. Campsite 2 requires a walk down a few stairs. It is a tight campsite with just enough room for a small tent next to the picnic table. A metal fire ring is on the opposite side of the picnic table. What I guess would be campsite 1 is further down the road and down below the road, I would not suggest using this site as it is a bit of a walk from the parking area, the road is two narrow to park here. Site 1 does not have a picnic table but does have a fire ring, odds are you won't even notice the site coming in or out. During my stay the campground did not have a fee, but the information sign indicates a fee may be coming next year. This is a dry campground, your only source of water is the lake so come prepared, this is also a trash-in trash-out site.
