After 2h of driving, during which you can admire the beauty of the national park, you finally reach the trekking path that leads to the mountains. You'll then embark on a hike of up to 4 hours to reach the lake hidden in the middle of the mountains. It's a magical sight, and well worth the long walk. After a lunch break with this panoramic view, you can cool off in the lake, then climb back down for 2 hours to reach the car.
