Next stop, California!

Prince William and Duchess Kate's Canadian tour is nearly over -- but before the royal couple jet off to Los Angeles on Friday, they stopped by the ENMAX Conservatory at the Calgary Zoo, Botanical Garden and Prehistoric Park.

Checking out the ENMAX Conservatory (one of the most energy-efficient greenhouses in the world, employing renewable energy technologies such as solar photovoltaic panels and geothermal energy), Kate unveiled her very last outfit for her 8-day trek through Canada.

After sporting an appropriately Western look (jeans and cowboy hat included!) for the Calgary Stampede, the Duchess, 29, looked demure in a red, knee-length coat-dress plus her trusty nude pumps; she wore her hair in half-up do.

Following an official departure ceremony in Calgary Rotary Challenger Park, she and William, also 29, arrive in Los Angeles late Friday afternoon.
