Hiked it in April - temp was about 65 and it was lovely. No snakes. There is 0.01% shade so I'd suggest March - mid-May best time to do it. June - Sept would be too hot for an enjoyable trek. Little or no water over the falls in the fall. Official Garmin round trip distance is 6.6 miles. Bring lots of water and sunblock and a hat. It's an easy walk around the west side of the temporary pond in the trail. As you crest the last ridge and can see the falls, watch for a single track path to the right that will take you in a more direct route to the falls. Keep you eye on your dog - mine got confused and thought we had headed back. A VERY bad place to lose a dog,
