If your family is new to mountain vacations, follow these simple tips for a happy, healthy trip.
Give the kids -- and yourself -- at least a day to acclimate to the altitude before you jump into organized activities.
Drink plenty of water to help ward off altitude sickness. Some symptoms to look out for are: headaches, light-headedness, weakness, upset stomach, and trouble sleeping. Call your doctor if you think your child might be ill.
Make sure you take extra water on hikes, and don't drink from streams or rivers. Even crystal-clear mountain water can carry giardia, a nasty intestinal parasite.
Take a front or back carrier for babies and toddlers. Mountain trails and some historic towns are not always stroller-friendly.
Pack clothes that kids can get grubby in -- not just their "vacation best" -- and include some warmer gear, since mountain weather can be unpredictable.
Remember to bring sunscreen -- the thin atmosphere makes it easy to get burned at high elevations.
