I haven't done it this year but a good place to start is Pioneer Park, then get out at , well, before, Tumwater Falls at Tumwater Falls Park. It takes an hour and a half, maybe 2 hours but I'm really not sure.. It's not something I've ever timed and there's always things to explore along the way. The river is real shallow in some places and a lot of people do it, but it's a fun way to enjoy the day. The river gets slow before the falls and you'll see the brewery, no mistaking where to get out I wouldn't think. It used to be you'd smell the yummy smell that came from beer brewing to let you know you're getting close. The brewery whistle blew at five and ending the float much later than that may put you in shade at the end, which can get chilly. You'll pass through a golf course where you can dive for balls. I hope I helped. Have fun and be safe!
