The Rocky Mountain National Park offers 360 miles of hiking trails. The trail to Alberta Falls suits the novice hiker, and it's a scenic trip from start to finish. The one mile round trip hike can challenge those not accustom to Colorado's high altitudes. The path has some steep sections as it parallels Granite Creek. Visitors can hear the fall well before it's seen. Late in autumn, when some waterfalls experience a sharp decline in water volume, this one still flows with gusto.
