Bothe - Napa Valley State Park offers a veritable plethora of activities to take part in while you visit, even if you are only staying for the afternoon.  Daytime visitors to the park can enjoy a leisurely stroll in Ritchey Canyon on the Redwood Trail 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 or perhaps even consider taking a horseback ride.  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.  For reservations of the group picnic site please call the park.
