Richard Hanson, managing director of our leading supplier Grand American Adventures, is the man to ask about the best time to go to the USA:
If you are visiting the south east, go in spring. Anywhere from Louisiana to Tennessee, the absolute best time is April. In summer, youíll get thunderstorms and oppressive humidity. October is also great, but you run the risk of hurricanes. In the desert south west the best times are spring or fall to avoid the heat and crowds. You donít want to go there too far into the winter either because you start losing the daylight hours. Colorado is great all the time. Even in spring, you have snow at night and crystal blue skies during the day.
