It's wonderful to have a relaxing bath in mineral water while looking out over beautiful scenery. If you live in the US or are planning a visit, consider going to one of the two natural hot springs (温泉) in the western US:
Travertine Hot Springs
At the edge of the Sierra Nevada Mountains near Bridgeport, California lie the Travertine Hot Springs. The orange, green, and red rocks and the mountains create beautiful views for you to enjoy while you bathe. Each pool is a different temperature, so you can find one that's comfortable for you. These springs can easily be reached by car. Take Route 395 south from Bridgeport and turn left onto Jack Sawyer Road. In about a mile you'll arrive at the springs. If you like to camp, you can camp along Jack Sawyer Road.
Bagby Hot Springs
In the middle of an ancient forest you'll find the Bagby Hot Springs. At the springs there are wooden bathhouses, with both private baths and communal baths. Through a system of pipes the spring water is brought to the baths at a temperature of 136 degrees Fahrenheit. If that's too hot buckets of cold water are also available to mix into the bathtub (浴缸) or to cool off with after your bath.
The Bagby Springs are about 45 minutes from Estacada, Oregon, on Highway 224. To get to the bathhouse there is a 1.5-mile walk from the parking lot through the beautiful Mt. Hood National Forest. While in the area, make sure to visit Portland, which is known for its coffee, restaurants, and music.
The best time to visit the two hot springs is in late spring, or in summer or fall. While in the area, check out the Curecanti National Recreation Area, where you can enjoy canoeing, fishing, bird watching, camping, and hiking.
