New York, N.Y.: Brian, is it a common thing to experience lightheadedness when visiting the Canadian Rockies? I had sight discomfort while visiting the Grand Canyon. Please advise.

Thank you,
Anna

Brian Patton: Most of the popular hiking trails start at 4500-5000 ft above sea level, below the height that most people experience altitude sickness. That said, there is less oxygen in the air at higher altitudes, and some people are more susceptible than others. The most common symptom is a headache. At higher altitude, dehydration occurs more quickly than at sea level, so plan on drinking plenty of water.

Boston, Mass.: When is the best or least inexpensive time to take a train trip across Canada roundtrip from Montreal and back for 2?

Brian Patton: The least expensive time is winter, but the warmer months are better. Try and book just before or after high season (June to Sept) to save money.
