Be prepared for an early start, that takes you on the road and into the crown jewel of the national parks. Did you know, Yellowstone is the world’s first national park? This mountain wilderness is home to grizzly bears, wolves and herds of buffalo and elk, and you’ll spend the full day exploring this huge and fascinating national park with your Intrepid leader. Visit Old Faithful and watch as it sprays over 4000 gallons (14,000 litres) of boiling water into the air, then be hypnotized by the rainbow technicolour of the Grand Prismatic Spring.
