The cache is located at one of the three lakes at the park. It is placed near the paved track that is surrounding the lake.
The cache is a micro cache that contains only a logbook. So, do bring your own pen/pencil to sign it. And please take good care of the ziplock bag protecting the logbook from getting wet. Do zip it back properly.
Be careful when retrieving and replacing the cache if you are coming during peak hours as there will be a lot of muggles jogging around or picnicking near the GZ. Plan your visit well and enjoy the beautiful scenery. If you are lucky, you may witness planes flying by from the GZ.
