A friend and I had intended to hike the entire length of the trail, spending the night near the river and then returning the next day. However, it was too hot and we were too dumb about our water supplies. We filtered water out of a foul-looking trickle at about mid-way in the day, but it wasn't enough. We spent a hot night at the shelter, hiked a bit more towards the river the next day, then turned back for the car. This was the thirstiest hike I've ever had, but it was due mostly to my inexperience. I think I would have enjoyed the trail a lot more if not for this error of mine. Take plenty of water!
