This is one of the best transitional class III-IV runs in California. Although the whitewater requires constant maneuvering, visibility is good, so you can pick the best route without getting out of your boat to scout. Despite the 100 fpm gradient, rapids are not as tough as the class IVs downstream, which are more dramatic affairs separated by pools and class II-III rapids.
Some people put in another mile upstream at a roadside turnout near the gas station in El Portal.
Put in above the highway 140 bridge, either from the steep left bank, or a ways upstream on the right bank. There is a pool before the bridge, but rapids begin immediately below. Sewage treatment plant for Yosemite Valley on the right. 1 Bridge and Red Bud picnic area, alternate put-in. Rafts usually put in here because the rapids are more wide-open downstream.
