Dress in layers
Winter weather can change quickly either way, so the temperature you find when you leave your house may not be the same two hours later. Dressing in layers lets you add or remove clothing to keep you body temperature just right.
Bring water and snacks
Everyone thinks of bringing water to drink during summer activities, but you still need to hydrate during the winter, too. If temps are cold and you will b outside for a longer time, consider using an insulated thermos to store water. Portable snacks like granola bars can give you an extra boost of energy while you spend time outside.
When you are out and about in nature using the buddy system is the best way to spend the day, especially when outdoors with children. People of any age can encounter problems for any number of reasons, from fatigue to a twisted ankle, so having other people near by in case of an emergency is important. Try to stay within sight of the people you are with, and don't let children go off on their own.
Know the conditions
If you are planning a trip outdoors in an unfamiliar area, try to research the local conditions head of time. Are there shelters/facilities close by? What is the terrain like? What are the weather conditions expected to be while you're there? Knowing the basic conditions will allow you to be more prepared when you arrive.
Take care of pets
Many pet owners love to bring their dogs out for family recreation time, but winter can be even more dangerous for pets than for people. Animals don't generally wear coats, hats, boots, and gloves, so they can be prone to frostbite, hypothermia, cut paws (from ice), or other winter-related problems if they are outside for an extended period of time.
Enjoying the outdoors int he winter can be a great time for families. By following these simple safety steps you will surely have a day to remember!
