Brook trout fishing and September solitude are the draws here. Lower creek sites suit tent campers who want water sounds at night; upper sites fit bigger rigs on the long aprons along FR 5130. First-come-first-served keeps crowds thin on weekdays.
No potable water on-site means hauling everything in, and early summer mosquitoes are genuinely bad enough that one reviewer called them 'a terror.' Privacy is thin in both sections, so close neighbors will feel close.

<p>This forested campground is located along Eightmile Creek. Easy access for trailers. On paved forest road #5130.</p>
The elevation is 2,600 ft. This pack it in, pack it out campground has two unnamed sections in a stand of Jeffrey pine. The lower section stretches along Eight Mile Creek in two spurs and is not suitable for travel trailers or motorhomes over 30 feet. This section has no understory so privacy is minimal. The upper section parallels Forest Rt. 5130 and features long, spacious, sunny parking aprons surrounded by grass and wildflowers, offering poor privacy between sites. This is bear country; practise safe food storage techniques.
Open mid-May through October 31
The parking aprons are gravel. RVs are permitted in upper section only.

The campground opens mid-May and closes October 31. Summer brings daytime highs between 65 and 80°F, with nights dropping to the 40s and 50s. The creek stays cold enough to feel refreshing but warms slightly by midsummer for comfortable wading. Weekends and holidays draw moderate crowds; weekdays are quieter. Early season means wildflowers and bugs. September offers solitude and cooler air, though nights get chilly.
Open into Oct with cooler nights and likely fewer mosquitoes; reviews sparse on seasonality.
Potable water is not available at this site. Vault toilet(s)
