Spring weather is quite unpredictable with park roads opening anywhere from mid-April through May. But if you don't mind monitoring the park website to know when the roads are expected to be cleared, you can witness a beautiful nature awakening and enjoy a pretty much empty park in its opening weeks.

Spring

Summers feature the best weather conditions with all park's facilities open, but it comes with hoards of people, adding hours to wait in traffic or in lines. We recommend avoiding July as the busiest month in the park.

Summer

The weather is still nice, there's plenty of active wildlife, and most crowds disappear in late August, making Fall one of the best times to enjoy the park. Lower accommodation prices come as a bonus.

Fall

Winters bring heavy snowfalls with temperatures rarely above freezing, so most roads, hotels, and activities are closed. You can only enter the park through the North Entrance, but you won't see much.

Winter

America's Wild Heart

Yellowstone – America's Wild Heart

The Grand Prismatic Spring is one of the most iconic and stunning geothermal features in the world. It is the largest hot spring in the United States and the third largest in the world, with a diameter of 370 feet and a depth of 121 feet.

The spring is known for its striking rainbow colors, which are created by the unique bacteria that live in the mineral-rich waters. The colors are particularly vibrant during the summer months when the water temperature is at its highest.

Take a boardwalk trail that leads around the edge of the spring for a closer view. One unique feature of the spring is its constantly changing colors, which shift based on the water temperature, time of day, and weather conditions. Despite its beauty, be careful to stay on designated paths and boardwalks, as the water can be dangerously hot and acidic.
