Seasoned kayaker John Cline paddles with a local hotel concierge along the Colorado River, periodically explaining that kayaking is perfectly safe for beginners and an ideal way to savor the pleasant Texas weather. Suddenly, the sky erupts and an onslaught of rain drenches the waterborne duo. They rest their paddles on their laps, look at each other, and start laughing. Rising Phoenix Adventures' kayak and canoe trips create these unique memories so regularly that one Belgian businesswoman even makes annual trips to the area just to ride the class-1 river. Since establishing the outdoor-excursion company in 2004 with barely 10 kayaks and canoes, Cline has more than quadrupled his fleet to accommodate the ever-increasing demand. After alighting one of the trusty vessels, adventurers set off to navigate through the river's islands and beneath a scenic half-mile tree canopy, where the shores offer glimpses of wild pigs, great blue herons, and undomesticated beach umbrellas.
