Definitely the most rugged backpacking trail I have ever been on. This hike is not for those who are not fit. Here are some tips for the hike: 1. The water, even in the springs has a strong salty taste after being filtered 2. There are very few spots for a decent campsite 3. The water is quite warm and there is a decent current and it can get deep in places 4. The trail has little to no shade during the late morning through late afternoon. Overall I would definitely do this hike again we had a great time, loved how quiet it was and had fun getting creative for a campsite.
