Located in the heart of the beautiful Napa Valley wine country, Bothe-Napa Valley State Park offers camping at 50 campsites, picnicking, swimming, and hiking trails that go through stands of coastal redwoods as well as forests of Douglas-fir, tanoak, and madrone. Daytime visitors can enjoy a leisurely stroll in Ritchey Canyon to view the delicate ferns and listen to the water splashing down the rocky creekbed. Bring your wine and cheese and picnic under the towering Douglas Firs. On hot summer days, grab a swimsuit and towel and come enjoy a dip in the park's swimming pool open on weekends, beginning on Memorial Day weekend through mid-June, then daily through Labor Day, from 12- 6pm. There is an additional fee for the use of the swimming pool, to be paid at the park entrance. The large picnic grounds are located in the day-use area, and are even available for group events and getaways. A covered area for group use contains picnic tables, a sink and an electrical outlet with a horseshoe pit and wheelchair-accessible restroom nearby. Whether you visit the back country on a several hour hike or take a mere stroll along the creekbed, you will enjoy a close-up look at all the natural beauty the park has to offer. There are well over 10 miles of trail for your indulgence. Summer temperatures may reach 105 degrees Fahrenheit, but nights are usually cool. In the fall, when daytime temperatures are more pleasant, the leaves begin to turn, creating a dramatic and colorful display. Temperatures don't often go below freezing and snow is infrequent, but nearly 45 inches of rain are apt to fall during a single winter - between December and March. Dogs are restricted to the camp and picnic areas and must be leashed. They are not permitted on the trails or in the pool area. The park is open 8am-sunset.
I did Ritchey Canyon to Spring Trail to South Fork to Coyote Peak, which looped back to the Redwoods Trail. This was 5.35 miles and 1,924 feet of climbing (according to Runkeeper).
I came across several deer on Ritchey Trail and a rattle snake up on the rocks of Coyote Peak Trail, so keep an eye out.
Don't bother with the last ascent up to Coyote Peak. It's gnarly and you really cannot see anything because of the trees! The best view is at the trail marker on the exposed rocks below the final ascent. I did not go up to the Homestead site.
I had no trouble following the trail markers to create my own loop.
Good trail with some small creek crossings, redwood trees, slight elevation change, some nice open paths, brushy areas, areas with poisen oak, wear good shoes as there are a few areas where you may slip if you dont have good traction.
