Calorie burn during hiking depends on body weight, pace, terrain difficulty, and fitness level rather than the specific mountain. Pinnacle Mountain State Park in Arkansas features a 2-mile round-trip trail with moderate elevation gain of about 350 feet. A person weighing 155 pounds hiking at a moderate pace on such a trail typically burns 200–300 calories per hour. For Pinnacle Mountain's moderate difficulty and roughly 1–1.5 hour duration for most hikers, expect to burn approximately 250–450 calories total. Someone weighing more burns proportionally more; someone lighter burns less. Faster hiking speeds and steeper sections increase calorie expenditure. To estimate your personal burn rate, multiply your body weight in pounds by 0.05–0.08 for moderate hiking, or use online hiking calorie calculators that account for your weight, trail gradient, and speed. Variables like humidity, altitude, and how much you stop affect the actual number. The precise figure matters less than understanding that any hiking burns meaningful calories and offers cardiovascular benefits regardless of the exact total.
