A skipper-led hour-and-a-half cruise through the Port Douglas waterways, with Captains Richard and Drew providing commentary as the boat drifts the mangrove-lined river. Crocodiles turn up on more than 90 percent of trips, especially through the May–November dry season. Two vessels work the route — the Lady Douglas and her sister sailing junk, the Shaolin — departing from the Crystalbrook Superyacht Marina on Wharf Street.
