Megan and Tyler of Good Trip Adventures put together an amazing itinerary for our visit to the Grand Tetons and Yellowstone. They shared information about the history, geology, wildlife, and so much more during the trip to give us a broader understanding of the parks in a way that was easy to digest. They are super personable, fun, and highly experienced guides that toured us to common points of interest (Old Faithful, Grand Prismatic, etc) but led us away from crowds to give us better views. They also added hikes to beautiful places that a commercial tour (or self-tour) wouldn't include. I highly recommend Good Trip Adventures for any trip to anyplace. Best trip ever!
