Spring in California is the best kayaking I have found, variety of kayaking for everyone’s levels and styles.
South Silver last weekend was epic, only on dreams you can see such a clean and steep section of whitewater, but I guess here is where the dreams come true. 600 feet per mile of awesomeness. This is a bigger sister of the Brush Creek down on the Kern river.
Start with finding good directions to the put in
The Middle fork of the Feather is an epic masterpiece of whitewater. Jaw dropping . The Devils canyon and Bald Rock both world class and if lucky you could do a 5 day trip , @1400 sounds ideal .
Also the South Branch of the Feather most be the only place on earth you can run waterfalls like that and no need ropes. A fantastic adventure for the waterfall lover.
