Explore the Dinosaur Island Adventure in Yokosuka's Soleil Hill Park

Discover the Exciting Dinosaur Island Adventure at Soleil Hill



The long-awaited immersive experience known as "Dinosaur Island" has officially launched at the Soleil Hill Park (Nagai Uminote Park) in Yokosuka, Kanagawa Prefecture. Visitors can take on the role of an investigator, embarking on a thrilling mission to uncover the secrets of Dinosaur Island.

This attraction is a revamped and enhanced version of last year's "Dinosaur Adventure," which ended last November. The previous exhibit featured awe-inspiring dinosaur displays, but the new format allows visitors to engage deeper in the story. As they step onto the island, they become the main character in an adventure that requires them to tackle various mysteries and challenges.

Upon arrival, guests are assigned a mission sheet at the reception and can begin exploring the park. They will encounter life-sized replicas of formidable creatures, including a Tyrannosaurus Rex over 10 meters in length and a Triceratops in its habitat. The experience gives guests a sense of adventure reminiscent of exploring an unknown island, as they observe the dinosaurs and look for clues hidden within the terrain.

As participants complete the challenges listed on their mission sheets, they can receive a Certificate of Investigation based on their performance. There are three ranks: C, B, and the prestigious A rank. Those who achieve the A rank are rewarded with a commemorative "Dinosaur Medal" as a token of their courage. The mission sheets are diverse, ensuring that visitors can undertake new challenges with each visit and dig deeper into the secrets of Dinosaur Island.

In addition to this main event, the park offers a variety of related activities. Visitors can participate in a "Dinosaur Fossil Excavation Experience," where they crush stones to uncover fossils and minerals, try their luck in the "Dream Dinosaur Lottery" for a chance to win great prizes, purchase various dinosaur-themed merchandise, and enjoy memorable photo opportunities at dedicated "Dinosaur Photo Spots".

As the spring break approaches, Soleil Hill Park is set to deliver an extraordinary adventure aimed at sparking curiosity among visitors of all ages.
