Dispersed camping areas near Marion, Wisconsin offer primitive wilderness experiences within the Nicolet National Forest. Most sites require self-sufficiency with no potable water sources and limited facilities. The terrain consists primarily of mixed hardwood forests with elevations ranging between 1,100-1,300 feet above sea level, creating moderate temperature variations between daytime and nighttime even during summer months.
What to do
Water activities: At Oconto River - South Branch, visitors can wade or fish in the clear waters. According to Rebecca B., there are "2 campsites at this trailhead, pretty well spaced apart" with a "clean and maintained vault toilet."
ATV trail access: Mountain Lakes Rd Dispersed provides direct trail access for off-road enthusiasts. One camper notes it's a "big site for ATV campers right off trail" where you can "probably get toy hauler in here easy."
Creek exploration: The McCaslin Brook area features a flowing brook suitable for cooling off during summer months. Christopher R. mentions, "The McCauslin Brook runs through Townsend and Lakewood. There are a total of 3 sites in this location and all are on the Brook."
What campers like
Natural soundscapes: The running water provides peaceful background noise at many sites. Nick H. describes Oconto River off Mountain Lake Road as a "very cool spot right on the river" with an "in ground fire pit" and "no service :)."
Spacious sites: The third site at McCaslin Brook offers exceptional room for larger groups. Robyn B. explains, "The site is so spacious and could easily be for a large group," though cautions about access: "the easement was really washed out and we bottomed our minivan coming in."
Affordability: Most sites are either free or cost $5 per night, making them budget-friendly options. At Oconto River - South Branch, Rebecca notes the area offers "Peace for $5" with two well-spaced campsites.
What you should know
Vehicle clearance requirements: Many sites have challenging access points requiring high-clearance vehicles. At Oconto River off Mountain Lake Road, Nick H. warns visitors not to "follow road past campsites, either way unless your vehicle is lifted" as a "sedan would have gotten stuck if I tried."
Limited facilities: Most sites offer only basic amenities. At McCaslin Brook, Rebecca B. describes "three pull-in areas, with picnic tables and fire rings just off the road" that are "shaded and right by the creek."
Cell service limitations: Connectivity is minimal or non-existent throughout the area. Zachary S. reports "AT&T: No Service" at Oconto River sites, while Rebecca B. found "no AT&T to speak of, but TMobile had 20 down/1 up" at McCaslin Brook.
Tips for camping with families
Site selection: Choose the middle site at McCaslin Brook for the best water access. According to hesselinkj@yahoo.com, "Middle camp site has best access to brook" and can accommodate "a 8 foot pop up" with space for "20 foot max" vehicles.
Insect preparation: Bring appropriate insect repellent as some areas have significant mosquito populations. Jack H. from Pioneer Park warns the "area is covered in mosquitos" and you're "right next to the highway."
Bring entertainment: With no connectivity, pack offline activities for children. Zachary S. describes how one night at Oconto River was "almost absolutely silent other than the waterfall (difficult to access) about a mile away."
Tips from RVers
Size limitations: Most sites accommodate only small to medium-sized rigs. Rebecca B. notes that at McCaslin Brook, "Two may be large enough to handle more than 1 small rig/tent/popup."
Solar considerations: Heavily wooded sites limit solar charging capabilities. Rebecca B. decided not to stay at McCaslin Brook "simply because it was so shaded. While that made it nice and cool, it made solar & Starlink impossible."
Entrance assessment: Always assess entrances before attempting to bring in an RV. Michael U. observed that McCaslin Brook has "tent and some pull through sites spaced down the road" with "maybe 4-6 total" sites available.
