The walk started out in an alternate location, Pioneer Park in Calistoga, but then continued around the normal track. One of the first places we passed was Saint Simeon Russian Orthodox Church with it's unique "onion" spire. With its Byzantine architecture and onion-shaped dome, it has been a part of the Upvalley community since the early 1950s. The Calistoga church was built for Russian immigrants from throughout the Bay Area who were buying vacation homes in the area. Parishioners of the church, numbering about 30, are mostly elderly Russian immigrants. Some members come up each week from Napa. The walk continued through neighborhoods with beautiful views of the hills. Twice we crossed the mighty Napa River, although the season and dry conditions reduced the water flow. The walk continued past vineyards with grapes ready for picking and leaves turning color with the season. The Calistoga geyser lived up to it's reputation and erupted for 5 continuous minutes. The town of Calistoga provided plenty of places to see, things to buy and food to eat.
