So here's the deal with frog rock, the kayakable lines are fairly easy straightforward, and not really to challenging. The danger of this rapid is the failure to make the move to the left at the end. The right side is bad news. It features two large undercuts with a sieve in the middle, ... it is an easy rapid with conqequences that can quickly become unsurvivable.

To Get There: The Railroad Bridge access is reached from Highway 24 mile 201.5.
Turn off on County Road 371 down towards the river. Cross the river and turn right headed downstream. In 3.3 miles from Hwy 24 you will reach the Railroad Bridge access site (camping and picnic area also available). To reach the put-in, return to Highway 24 or alternatively run your shuttle on County Road 371 which continues as a dirt road on river left before crossing back over to river right just before town. Either way, it's 6.7 miles downstream to Buena Vista. Take the main street in town east toward the river, past the ballfield, and down to the public access on river right.

See Colorado Rivers and Creeks II, by Banks and Eckardt (The Bible), for info on this and most of the other runs of Colorado.
