Explorer cruises are an adventure-style experience traveling at speeds up to 45 miles per hour. You are welcome to bring food and drink on board. The Explorer is an open-air boat and not climate controlled; please dress for weather. Although the boat is covered, there is an uncovered deck in the back. Please note that river conditions vary and may result in frequent, sustained turbulent motion along with varied weather. For safety and comfort, guests should be in good health and without conditions that could be aggravated by motion. Please consult your doctor prior to booking a cruise on the Explorer if you have a health concern. The boat is not wheelchair accessible.
