Any varnish that's rated for outdoors should work fine. I'd be hesitant about varnishes that are indoor only, I have some tables that I did with indoor polyurethane and they're cracking now.

There's a really good book called understanding wood finishing by Bob Flexner that I highly recommend if you want to learn more about finishing.

It's just wood, so any place that deals with outdoor wood furniture should have stuff that will work for you.
