Paddling Redfish Lake requires a little pre-planning. First of all, pick a campsite and make reservations!! It is very crowded throughout the summer and the Point, Outlet, Glacier View and Mt. Heyburn campgrounds are usually booked months in advance. (For reservations go to: http://maps.reserveusa.com/static/id1.html) Then click on the campground you want to check availability.
Even if you dont own a canoe or kayak you can still paddle Redfish Lake. Canoes and Kayaks are available to rent for a reasonable fee at the boat dock near Redfish Lake Lodge (http://www.redfishlake.com/marina.html). This is a fairly large lake and the water is very cold so stay close to shore if in a paddle craft. Powerboats are common on the lake, however most boaters observe the speed limit near the boat dock so large wakes arent a major problem. The views of the Sawtooth Mountains just past the point are incredible and worth a look.
There is a lot to do at Redfish Lake besides paddling. The visitors center and nature trail along Fishhook Creek is an interesting site and great for kids. In late summer you can walk along the boardwalk trail and see Kokanee Salmon (that give the lake its name) spawning in the creek.
Redfish Lake Lodge has rooms and cabins for rent but reservations are a must!
