We should possibly consider one or two hiking trips. Here is what I found so far: Keplr CascadesThis is on the way into the park, one of the first stops and is a quick little pull-off Est. time ~15 minutes. This is a view of a waterfall on the firestone river about two miles south of old faithful village  Lower Falls in the Grand Canyon of YellowstoneHike in from the north rim trail There are staircases and railings but it is still a moderate to hike with some serious elevation change 308’ tallest in the par Mammoth Hot Springs Northern end of the park Mud Volcano (smells bad) The mud volcano is located southeast of canyon village and is another boardwalk hike around a 0.6 mile loop. In this hike, you will see the famous mud volcano as well as some of the most acidic features in the park, plus dragons mouth spring, sour lake, sizzling cauldron, and more. This is an easy hike but be warned that it smells bad thanks to the sulfuric gasses rising from the ground. Yellowstone is a massive volcano, often referred to as the yellowstone supervolcano. Much of the park sits above the yellowstone hotspot, from which hot magma floats toward the surface and heats pockets of water and gas which create the geysers we see in the park. But don’t worry, geologists studying this volcano say it is unlikely we will see any major eruption in the next couple hundred years.  Yellowstone LakeIt is easy to get swept away with views of the amazing geysers, but Yellowstone lake is beautiful # in itself. Located at 7700 feet above sea level, Yellowstone Lake is the largest high elevation lake in north america. It is also home to the largest population of cutthroat trout which originated from the pacific ocean. This puzzled scientists for decades, as the lake drains to the atlantic ocean with no streams connecting it to the pacific. The water remains cold year round, so I don’t recommend trying to swim The Norris AreaThere are two main loops in the norris geyser basin; named the porcelain and back basins Porcelain basin loop is about 1 mile long and is an easy boardwalk hike Back basin is about 2.5 miles and is an easy boardwalk hike but you can take shortcuts as needed. This is home to the the tallest geyser in the park, Steamboat geyser. Unfortunately, you’ll need some serious luck to see this one erupt, as it can go as much as 50 years between eruptions. In these pools, you will see rainbows of vibrant colors thanks to the microorganisms living here. Each temperature range is ideal to a different group of organisms and therefore, the colors act as a thermometer  West Thumb Geyser BasinTBR Midway Geyser BasinThis is a popular spot for instagram photos, as you get classic yellowstone colors and it is a very short walk from the parking lot. Because of that, it gets really crowded
