It's a very popular place so you need to be sure and get a reservation and check for avaliability. They have redone their launch ramp this year and i'm not sure if their finished yet. Also this year the water level has been low in spots and they've been flushing the damms up above so this has created sandbars in abnormal places. Most will be north of moabi and south of moabi as you enter the gourge. Good luck. Give the park a call.
