Old Faithful Geyser of California

Old Faithful Geyser of California is the most kid-pleasing hour in Napa Valley and a reminder that the region's hot springs come from real volcanic heat. On a private property on Tubbs Lane just north of Calistoga, a geyser fed by underground water heated by the area's geothermal system erupts on a regular cycle, sending a column of steaming water high into the air for a few minutes before subsiding. According to the site, eruptions come about every fifteen to thirty minutes year-round, so there is no schedule to chase: you buy a ticket, find a bench in the viewing area, and wait a short while for the hiss and roar. Around the geyser the owners have built a relaxed attraction that suits families and anyone who has had enough tasting rooms: a small geology museum explaining the geothermal system and the region's volcanic past, a heritage animal farm with goats and other animals, native gardens, bocce and lawn games, picnic areas with a complimentary picnic station, covered lounges and a gift shop. Leashed dogs are welcome, parking is free, and the paths are mostly flat and accessible. Admission is a modest fee per person, cheaper for children and free for toddlers, and tickets stay valid for twelve months. It is a little old-fashioned and some visitors find the price steep for the time spent, but with a picnic and children in tow it easily fills a happy hour or two, and it costs far less than a single winery tasting.

What you are seeing. Calistoga sits in a geothermally active corner of the valley, which is why the town has been famous for hot springs and mud baths since the nineteenth century. Old Faithful is one of the few places where you can see that heat break the surface. Heights and intervals vary with conditions underground, and the site has had quieter spells in the past, but its current cycle is frequent enough that most visitors see several eruptions in an hour. The museum and signage explain the plumbing of a geyser in terms children can follow.

Visiting well. The site opens every day of the year from morning, with longer evening hours from late spring through summer and earlier closing in the off-season, so call ahead on holidays. Bring or buy a picnic and use the tables and the free picnic station; the lawn games keep children busy between eruptions, and the goats are a reliable hit. Bicyclists who ride in get a reduced rate, which pairs well with the Vine Trail's Calistoga end. Allow about an hour for the geyser and farm, longer with lunch.

Pairing it. The geyser is five minutes from downtown Calistoga and close to the Petrified Forest, which makes a natural family half-day: geyser in the morning, petrified redwoods next, lunch on Lincoln Avenue, and a swim in a hot-springs pool in the afternoon. Adults can add Sterling Vineyards or Castello di Amorosa, both of which have family-friendly options, with a designated driver for the day.
