We took a self-guided tour, rented a canoe from Willow Beach Marina grabbed a few beers and snacks from the on-site store and had a memorable fun time. The views are truly breathtaking!! The staff at the marina are top notch - super friendly and informative. If you have time, I would recommend renting a car and driving to the marina from Las Vegas (about an hour drive), the views driving are amazing and can only truly be appreciated in person. Absolutely a must see and do, would love to go again some time. Since the marina is located in a National Park you do have to pay a park entrance fee of $25 per car if you do not have a season pass. Truly worth every penny!!
