Child at Midway Geyser Basin

The thermal features at Midway Geyser Basin may not gurgle and spout but they are brightly colored and colossal. At 370 feet (112.8 m) wide Grand Prismatic Spring is the largest hot water pool in Yellowstone and third largest in the world. Yet what makes this hot spring truly stunning is its ringed perimeter, green, yellow and orange. Excelsior Geyser, a gaping crater 200 x 300 feet, discharges more than 4,000 gallons (151,000 liters) of water each minute. And while Excelsior no longer acts like a geyser its orange and yellow carpet ushers run-off in elegant fashion.
Getting There
Midway Geyser Basin is located 6 miles (9.5 km) north of Old Faithful and 10 miles (16 km) south of Madison Junction. The road from Old Faithful to Madison Junction is open to wheeled vehicles from mid-April through October and is open to oversnow vehicles from mid-December to mid-March.
Getting Around
Midway Geyser Basin Trail is an easy 0.5-mile (0.8 km) loop. The trail is wooden boardwalk. Steep stairs limit accessibility for wheelchairs and strollers.
Things to Keep in Mind
Keep to boardwalks and trails. Swimming and bathing is prohibited in all hot spring pools. Do not throw objects into geothermal features. There is no shade at Midway Geyser Basin. There are no concessions between West Yellowstone and Old Faithful. Pack water and snacks. Wear sunscreen and hats.
