I am going on the American Parks & Canyons plus Little Big Horn tour April 26th 2012. What sort of temperature is it likely to be that time of year ? Will i need hiking boots ? And finally could you please tell me the name of the tour guide .

Anna from Wales.

The temperature can be quite unpredictable at that time of year. It could be anything from quite cold to very hot, so I would pack for all conditions. It's very unlikely to rain, though, so you won't need waterproofs.

You probably won't need walking boots unless your ankles need extra support when you're walking in countryside. If you do take them, it might be worth wearing them on the flight to keep your luggage weight down.

We haven't appointed a tour manager yet but if you can write again a month or two before you fly, I should be able to let you know.

Kind regards,

Olly, your editor
