Yesterday, my girlfriend and I were all ready to go with our gear and day free for the narrows when we found out that Zion was requiring reservations for the park shuttles. Parking at the narrows was not allowed during this time, so shuttles were necessary, however the park shuttles were all sold out until the next day. We were told our options were to walk, bike, or rent a private shuttle, and as the narrows are 8 miles from the entrance, we wanted a shuttle. I called Southwest Adventure Tours, and the owner Jason quickly answered the phone and was extremely polite and had a shuttle ready to go next to the gate and visitor's center where we were. Within minutes, we had paid $30 each for roundtrip tickets, which was cheaper than any other private shuttle service, and our driver Wayne was the nicest person I've ever met and took us up there, with just the 2 of us being on board. Our experience was just as good on the way back. Within minutes, a Southwest Adventure Tours shuttle was ready for us at the narrows even though we finished earlier than we made the reservation for and took us right down. The service could not have been better!
