The lower Colorado River is moving flatwater with no rapids - just beautiful green waters. It is perfect for beginner and seasoned paddlers alike. Travel across the Mike O'Callaghan - Pat Tillman Memorial Bridge, into Arizona. Your destination is Willow Beach, where you will load your kayaks, and gear up for your journey on the Colorado River. Kayak past the Fish Hatchery, toward the emergence of a historic trailhead. Take a break and enjoy a short hike with spectacular views. Explore the ruins before returning to the kayaks. Back on the river, the green waters of Black Canyon flow through a narrow channel, where Emerald Cave is hidden. Paddle inside for a great photo opportunity. Watch for Desert Big Horn sheep, bald eagles, coyotes, and striped bass. Beyond Emerald Cave and the catwalk sits a sandy beach, where you'll enjoy a picnic lunch with million dollar views. Take a refreshing swim in the green waters of the Colorado River before kayaking back to Willow Beach.
