If you’re on the river, float under the bridge and slightly around the bend. Look river left and you’ll see a small dirt pathway towards the end of the day use area. This is the ramp. If you’re putting in here, drive around the loop and you’ll see the put-in location easily. Parking is limited and hide your valuables. There are pit toilets here, but no water. The screenshot below is pinned with the dirt put-in location.
