It depends! You'll need to factor in flights, car rental, hotels on or near the rim, gear (clothing, shoes, hydration pack, trail snacks, medical supplies, hiking poles, etc). This hike is an investment that I think is worth it, yet should be taken seriously. You want good gear to avoid unnecessary chaffing, blisters, heat rash, proper hydration throughout the hike, and the right kind of energy foods. This last trip, I spent $1200 in flights, rental car, hotels, food, etc.
