Israel Nahal Ayun

It's a short hiking trail with few beautiful waterfalls.

Good for long exposure shots, but take filters - too much sunlight almost at any time.

There's a free parking right near the entrance to the National park. The entrance to the park itself costs around 20 NIS.
Location is very beautiful, but full of people, avoid visiting on weekends and holidays.
Opening hours are seasonal, make sure to check before visiting.
Very important: you will be allowed to enter not less than 2 hours before closing, park stuff is very strict about it.
