One of the best hiking experiences I had so far. It’s definitely a tough one if you are not a pro. We hiked up-to Nevada falls with our 5 month old in the carrier and it took 3 hours and 20 minutes from happy isle. Like I said, the hike is tough but it totally worths it. Take enough water and food with you. They have water refill station and restrooms at the foot bridge only. None of them at Clark point. We had gone out of water by the time we hiked up the Nevada falls. But the water from the stream seems pretty clean and we drank it and had no reaction afterwards.
