When Dr. Doug Diekema isn't in the emergency room at Seattle Children's Hospital, there's a good chance he's out on the trails.

He developed a passion for the outdoors as a kid. One that he's passed on to his children and now wants to share with others.

"I don't think there are many things that are better for kids than getting outside and enjoying some exercise in a beautiful place," said Diekema.

But it's important to stay safe and that means preparing for every possibility. Dr. Diekema recommends parents carry a backpack with all the essentials just in case. You'll want to bring water, snacks, sun protection, extra clothes, first aid kit, light source, compass, map and finally a garbage bag — but not for trash.

"In a pinch, [if] I encounter somebody who's cold and wet, I can make a rain jacket," said Diekema. "I can stuff it with leaves and make a couple of holes for the legs to create a little sleeping bag for somebody to keep them warm."

Another tip Dr. Diekema gives involves how long your hike should be.

"As a general rule, you can take your child's age in years and that's about how many miles they're going to be able to walk," said Diekema. "A three year old is probably going to be able to walk around three miles and a six year old around six miles."

Remember, the ultimate goal is to have fun. You want your kids to enjoy the wilderness and have a good time.
