If you're planning a bucket-list adventure through Yellowstone National Park, don't miss Grand Prismatic Spring — the park's most colorful and captivating natural feature. Its vivid rings of blue, green, orange, and red are caused by microbial life and minerals, and the view is truly breathtaking.
What Makes It Special
- It's the largest hot spring in the United States and third largest in the world
- Its vivid colors change with temperature and light conditions
- Located in the Midway Geyser Basin, it's one of Yellowstone's most iconic attractions
Senior Travel Tips
- Best Viewing Spot: The overlook on the Fairy Falls Trail offers the best panoramic views — a 1.5-mile round-trip hike on a well-maintained path
- Parking: Arrive early (before 9 a.m.) or late afternoon to avoid crowds
- Mobility: The boardwalk loop around the spring is accessible but has some slight elevation and steam areas — wear sturdy shoes and bring water
- Photography: Morning light gives the clearest view of the vibrant colors
What to Bring
- Sun protection and layered clothing (weather can shift quickly)
