"Outside with Greg Aiello" is an adventure/travel show that explores both international and domestic national parks and scenic wonders beyond the crowds and popular tourist stops. The series is hosted by Greg Aiello, who was born and raised in Yosemite National Park in central California. Greg's love for the outdoors led him to work in the wild as a mountain guide, leading clients into the highest reaches of the Sierra Nevada Mountains in California. In season two, Greg journeys to the mountainous Caribbean island of Dominica and to the Nordic nation of Iceland. He tours Dominica to see how the people and its tourism industry are rebuilding after being nearly wiped out by Hurricane Maria in 2017, and visits Iceland to see how fire and ice co-exist in a place that is rapidly growing as a top travel destination.
