Did you know that you could easily burn 500+ Calories in less than 60 minutes on a vigorous hike? Going 30 minutes out on the South Fortuna Trail (one of my favorites) and back will scorch the calories. Add weight in a backpack or extend it longer and make it to the summit and you could be getting closer to a 1000 calorie workout. This type of exercise that mixes low, moderate and high intensity for a long duration is incredible for targeting fat and increasing cardiovascular health.
