What an amazing experience! Definitely worth an inclusion into any itinerary, although if riding (cycling) through, the accessibility could prove a little challenging for casual riders, given the undulating terrain and sweeping bends.
That said, the night home (with a guide) is highly recommended. Our guide had the sharpest eyes, matched only by the extensive knowledge of the foliage and fauna found in the forest surrounding the area. Three hike thoroughly enjoyable.
The staff at the centre were also very warm, affable and welcoming and we felt right at home in the lush, verdant surroundings. Big thank you to Momoka-san of the visitor centre for her laughter and impeccable English, and for sharing her insights of Okinawa!
Have tent camped here twice, and it has been fantastic each time. The staff are very professional and friendly. There is a lot to do here, and their facility can handle large groups (we met a group of about 90 campers there).
There is a large obstacle course here as well, but many of its parts are broken and pose a potential danger. If you have kids, there are plenty of other things offered, like night hikes, kayaking, etc.
We stayed overnight in a family room with breakfast and dinner. The breakfast was Japanese and the portion is small. It may not appeal to those who prefer bread and butter. However, the dinner was delicious and the portion was large. The kids had a different dinner menu with some dishes similar to the adult meal.
Our room does not have attached bathroom, but it was not inconvenient at all as the toilet was just outside our room. In addition, there's a public bath, indoor and outdoor, on a separate building. You can use it from five in the evening till ten at night.
The nature walking paths are closed after five and certain paths require an entrance fee.
The playground is located at a different place and you'll need to drive to go there.
The general location is good if you're going to see the Yanbaru Kuina at Ada.
We came for a day trip to get more information. We hiked the accessible trail and wild boar trail. Both were very nice. We were interested in river song tour but was told our son needed to be 10yr. We could have missed interpreted what she was saying. The lady helping us in the visitor center was very accommodating and kind. She gave us maps and information. You pay for the trails at the visitor center too. ¥300-¥100 person depending on age.
