This is a geothermal area with several mud pots, fumaroles and has a short walking path with a very strong sulfur smell to it (obviously). It is worth your time, especially if you have not been to Yosemite NP (probably the largest geothermal area in the world). You can continue your journey up a hill but it only leads to a scenic lookout area overlooking the geothermal area and the surrounding valley.
