People often ask me what time of year is best for train trips to Copper Canyon. That is a hard one to answer because each season has its own draw. Let me say that I do not recommend June ( both hot AND dry). But all other times of the year are great.
Here are some highlights for each season.
Spring- very dry and weather is easy to handle.
Summer- starting July 1 or so it rains often. This greens everything up and the water falls flow.
Fall- green and cool- some think this is the ideal season, but it can get stormy.
Winter- nice at lower elevations. We might get a snow at higher places.
Here is our 2012 calendar for Copper Canyon tours– including both New Years trips.
