Canon 70-200 F4.0 non IS

It's a great travel lens when paired with a WA zoom. I use it with the 17-40L on a 5DII. That's if you don't mind the weight. I travelled to Spain last spring to visit my daughter and walked around various cities for nearly 4 days carrying that combo in 32 degC heat. My wife and daughter thought I was crazy and by the end of day 2 I had to agree with them. I'm off to visit my son in Oz and NZ in March and am serously thinking of getting a smaller lighter APSC-type camera with fixed zoom lens just for travelling.
