The elevation is 1,100 ft. The campground has three unnamed sections. One section is located along Trinity River with several campsites overlooking it. Because this section is along the river, it has a greater variety of trees including Pacific Madrone, oak, and Ponderosa pine. The other two sections are located across the road away from the river. One of these sections is held in reserve for groups and is not included in this survey. The other section is a large loop around a grassy area and dotted with Douglas fir. This section is ideal for overnight stops or longer stays. This is bear country; practice safe food storage techniques.
Open May 15 through October 31.

Best season: summer. Summer is the best time to visit because warm, stable weather (daytime highs typically in the low- to mid-70s°F, evenings in the low-50s) makes the Trinity River ideal for swimming, kayaking, and shore-side lounging. River-based activities and fishing are at their peak, trailheads are fully accessible, and the three group sites are most usable without snow or muddy roads. Expect moderate crowds on summer weekends (the campground is small so sites fill fast) and plan ahead for possible fire and ( Peak months: July, August, June, September Avoid: October, November, December, January
Summer is best: river warms for swimming, boating and sites fill quickly; reviews most praise summer visits.
