Imperative that you remember to bring a strong bug repellent just in case. Horseflies hurt and draw blood when they bite. Make sure you know where you're going as this is in the middle of nowhere on a paved road followed by sandy or dirt or mud or washboard sections. The parking is on a dirt and salt hard surface. The short walk to Blue Lake is on wooden boards of all shapes, sizes and types. We were at this large geothermal pond, about 16 miles south of Wendover, to meet members of a Boise, ID scuba diving group. The water is warm and clear enough to be used for scuba diving training. Besides this group, there were two people on the pond, one on a paddle board and one in a river tube. There were two people snorkeling. Two men were flyfishing from the shore wearing long sleeves and long pants. Besides bug repellent, bring, at a minimum, drinking water. Either eat before you come or bring food. There is this pretty pond/lake, with a parking lot, a wooden boardwalk, surrounded by marsh and tall grass, hidden in the desert.
