Mushroom hunting: Spring camping trips coincide with morel mushroom season. Art S. observed at Camp Cadiz that "it was also morel mushroom time so some people were hunting for them." The oak forests surrounding Grantsburg provide ideal conditions for mushroom foraging in April and May.
Rock climbing: The limestone bluffs offer climbing opportunities throughout the region. Joel R. mentioned that near Backpack Campground, "there are several limestone bluffs, great for climbing, naturally forested woodlands, cliff caves, and several small waterfalls."
Fishing on the Ohio River: The riverside location of Tower Rock Campground provides direct water access. One camper noted, "Campground is smaller but the sites are spread out well... right on the river so may be closed during flood seasons." The Ohio River supports catfish, bass, and crappie fishing.
What campers like
Private, spacious sites: At Turkey Ridge Campground, camper David H. appreciated "#35 is a nice location. Large yard and not super close to other campers. #53 is smaller but very private." These sites accommodate multiple tents per site.

Off-the-beaten-path solitude: Many campsites in the region offer seclusion from crowds. Jeremy G. chose Camp Cadiz over Garden of the Gods camp because "Cadiz was spacious, quiet, and the other campers wanted to camp not party. Stayed an extra day because of it."
What you should know
Hunting season impacts: Turkey hunting season significantly affects campground availability and atmosphere. Art S. observed at Camp Cadiz: "Camp filled up with hunters who started generators at 3 in the morning to get ready to head out for turkey." Spring turkey season runs April-May, with additional seasons in fall.
Toilet facilities vary widely: Vault toilets are standard but conditions fluctuate. TJ V. noted at Turkey Ridge that "There are 'out houses' close by. Although they were pretty bad my buddy said 'storm of flies came shooting out the hole like a tornado.'"
Road conditions can be challenging: Many campgrounds require navigating unpaved roads. Art S. described the approach to Tower Rock Recreation Area: "The road is deceptively smooth. Ruts and water crossings appear suddenly."
Flooding closures affect riverside sites: Campsites near the Ohio River experience seasonal closures. J C. noted about Tower Rock: "right on the river so may be closed during flood seasons." Spring camping requires checking current conditions.
