The Grand Prismatic Overlook trail at Yellowstone National Park offers a breathtaking hiking experience. It features a scenic route that passes the Firehole River and leads to a remarkable view of the park’s largest hot spring, the Grand Prismatic Spring. This 1.2-mile round-trip journey is considered easy to moderate. It ascends through a lush forest before culminating at an overlook that presents an expansive view of the vibrant thermal spring below.
From this vantage point, hikers can see the full spectrum of the spring’s microbial mats, creating a brilliant display of oranges, yellows, greens, and blues. The trail doesn’t stop there; it continues towards Fairy Falls, offering a longer trek to one of the park’s most enchanting waterfalls.
For an optimal experience, pack water, wear sun protection, and choose sturdy footwear. The trail’s popularity may lead to crowds, but the combined beauty of the Firehole River, Grand Prismatic Spring, and Fairy Falls makes this hike an unforgettable Yellowstone adventure.
