Alexis is an outstanding tour guide. She makes all of her trip- goers feel welcome and does a great job throughout the day keeping the group together. She is a wealth of knowledge about the National Parks in the area and shares current and historical information throughout the tour. As another reviewer mentioned, you may want some extra snacks for the trip or to go with your sandwich at lunch. The sandwiches are hearty, but if you like chips or fruit with it, take that. Alexis is also great with suggestions on other adventures in the area, restaurants, and pretty much anything thrown at her. She really creates an enjoyable day, and gives her guests a break from the hassle of traffic, parking etc, so your attention can really be on this gorgeous place you're visiting.
