I was in the area with family in August a couple of years back.
The trail was really short from the parking lot. The Falls was pretty though a little crowded and busy. There will be people walking in the water. Be careful if you are walking through the water. Also, there are giant rocks and logs to sit on.
I feel like Tiffany Falls is somewhere you go in the autumn. You would see the leaves being colors.
There's a small fee enter (around $11/vehicle). It's done through a park kisok. You can use the same parking ticket at Sherman Falls within around 2 hours or so. The price not too bad for vehicle with at least 3 people.
The parking area is really small. If you visit in the afternoon, you are going to wait a bit or park at Sherman Falls and walk (around 20 min) to Tiffany Falls. There isn't really a closer relatively larger parking lot. read more
