Groups planning a Bay Area day-and-night outing in spring, when the hills are green and trails uncrowded. Arroyo Flats has a fire circle, five picnic tables, and a double BBQ already set up. Book by phone at least 3 days out, and bring a beer/wine permit ($25) if that's your crow
Families or couples wanting a solo site won't find one here. It's a single group reservation, requires advance phone booking, has chemical toilets only, no showers, and summer visits mean dry grass and hot trail conditions that reviewers found rough.
Compare with similar sites, watch availability, and build a packing list — Camp Sage handles all of it.
Spring is the sweet spot here. Daytime highs reach the mid-60s to low-70s°F, with mornings in the mid-40s to low-50s°F. The hills are green, wildflowers bloom, and trails are at their most scenic. Weekdays and early-season weekends stay uncrowded. Summer brings dry grass and temperatures climbing to around 80°F. Winter sees rain that greens the hills again, with afternoons around 57°F and crisp mornings near 43°F. Late summer and fall require fire-season caution.
Spring is described as the 'sweet spot' with green hills, poppy blooms and ideal temps.
