Did a quick day hike last weekend to Goldbug Hot Springs in Elk Bend, ID. It's a little under 2 miles one way, and about 900' elevation gain - half of it in the last quarter-mile. You start at a trailhead next to private land and hike about a quarter-mile through private land (it's allowed but stay on trail, dogs on leash and keep your noise level down).
It was very hot in the afternoon and there is little cover, it improves as you approach the hot springs. The springs actually spring cold water and hot water, and some pools are hotter than others, so explore!

We are in the middle of a heat wave. I think it was in the 90s F when we hiked it at 3 pm. Lots of sunscreen needed. Luckily there is a stream that comes down so if you bring a filter, you will have safe water for sure. Thankfully around here there is pretty much always water to be found in the mountains!
