Overview

Hype:

Fantasy Island (Fantasiens Ø) is located in Breddam Sø in Præstevagen in the northern part of Store Dyrehave near Hillerød. Fantasiens Ø was established by Frederik VII in 1859 in connection with securing the water level in Frederiksborg Slotssø. When a canal was built, a small island was cut off from the mainland, and here the king had a romantic structure built. There was a Gothic-style gazebo, a toilet shaped like a stone mound, a grotto with moss benches and various fountains.

After the king's death in 1863, the facility was no longer used. In 1969, the buildings, except for one gable, were demolished. The ruins are visited annually by 30-50,000 guests.

Story

After the castle, we drove south a few minutes where they have some gardens and forest area. We hiked to Fantasiens Ø, which is also called the Island of Imagination. It’s where one of the kings had a little retreat next to a pond. The only thing left is a wall and foundation, but it looked fun and we enjoyed being in nature. 

Along the trail, there were a bunch of brown things that looked like dog poop but ended up being snails. We named them the dog poop snails.

After viewing the ruins, we took some random trails through the forest looking for what was labeled as a parkour playground on the map. The map wasn’t very detailed, so it took some guessing, but we eventually found it and had fun jumping from logs and climbing over things.
