Trail Bay campground
Trail Bay
Located in the heart of Yellowstone National Park, the Trail Bay Camping Area offers easy access to popular nearby points of interest such as Old Faithful, the Grand Canyon of Yellowstone, and the Norris Geyser Basin.
The campground offers several amenities, including restrooms, fire pits, and picnic tables. The campground is available on a first-come-first-serve basis, and there are 19 campsites available.
An interesting fact about Trail Bay is that it is actually a man-made bay created by the construction of the Shoshone Dam in the early 1900s. Today, the area is a popular spot for fishing, boating, and hiking.
The best time of year to visit Trail Bay Camping Area is during the summer months, from June to August, when temperatures typically range from 60-80 degrees Fahrenheit. However, the campground is only accessible by boat or hike, so visitors should be prepared for a bit of adventure.
