Start to hydrate! You tend to lose water as your body acclimates to altitude and this leads to dehydration. Colorado is also very dry, so drink lots of water :) Summit County (Keystone/Breckenridge) is home to some of the best skiing in the nation! We will be getting married at the Keystone Ranch which is located at 9,200ft at the base and the ceremony will be located at over 11,000 ft!
The weather is gorgeous! 70s during the day, but it does get chilly in the afternoon/evening so bring a jacket.
