Hiking is a great outdoor activity that can burn loads of calories while having fun with friends and family. I love being outside for my exercise sessions and would pick that any day over going into the gym. For the average person, you could burn an average of 250-400 calories per hour depending on the terrain and pace.

Some safety reminders when you are hiking:

*Take plenty of clean, cool water. You should be drinking constantly during the hike. Remember to hydrate prior to going and bring extra water in case you are out longer than planned. There is nothing worse than getting a heat related illness that could have been prevented by hydrating properly.
*Wear a hat, sunscreen and eye protection. This will protect your face, head and skin from direct sunlight and sun damage.
*Tell someone where you are going and when you should be back. Even if hiking with a partner, always let a 3rd party know in case you have an emergency. If you don't return on time, help will be sent sooner than if no one knows you are missing!
*Time your hikes. Try to go when it is cooler and when creatures are not lurking. Dawn and dusk are often times animals (like snakes) come out for cooler weather so if you are planning a time that is similar to theirs, be aware of your surroundings.
*Bring your cell phone. Even if you can not get a signal where you are, often emergency signals will work to notify someone that you are in trouble.
*Always pack a high energy snack filled with complex carbs, protein and unsaturated fats to eat half way through. This will give you energy on the return trip to maximize your endurance levels.

All in all, enjoy the time outside, challenge yourself and burn calories at the same time!
