We kayaked Bear Creek at least 4 times this past summer. It is open from Memorial Day to Labor Day. We brought our own kayaks and paid $10 to Bear Creek Canoe Run (contact info and directions on Facebook, canoe and kayak rentals) for a lift from our car to where we put in. I'm not sure if our route was exactly the map below as there are other places to put in that I'm not familiar with in the area.
Overall, Bear Creek is a beautiful, easy day trip. It's about 6 miles, and you can stop, eat lunch, swim, and enjoy the view from a large rock that is a little less than half way. The kids with us were easily able to kayak with their sit-on-top kayaks. Canoeing is popular, but kayaking is much more fun on Bear Creek!
