Tips for a Great Tour
Touring FLWO is always the experience of a lifetime, whether it’s your first visit or your 50th. To make it an even better experience, please remember:
Arrive between 8:30am - 9:00am. The tour video begins promptly at 9am and the bus departs promptly at 9:30am. We cannot hold the bus for late arrivals.
Bring your lunch, water and sunscreen. Tours of FLWO are an all-day adventure and there are no facilities for purchase of these items during the tour.
Bring a sweater or jacket. The mountain is 15-20 degrees cooler than the Visitor Center.
