River Road in Canyon Lake crosses the Guadalupe River four times as it winds 10.6 miles between Loop 337 and Canyon Lake Drive in the picturesque Texas Hill Country. A great way to take in the skyscraper cypress trees and colorful limestone bluffs is by tubing down the river. Outfitters offer shuttles that will bring you back to where you started. The river banks are lined with camping sites, concession stands and restaurants. Traveltex.com
