Forest Adventure Okinawa: Ziplines with Kids in Onna (2026)

Somewhere between the beach days and the aquarium, most Okinawa kids hit a wall: they want to climb something. Forest Adventure in Onna is where that energy goes to die happy — a treetop obstacle park with real ziplines, wobbly bridges, and a harness that clicks the whole way around.

It sits in the green hills of Onna Village, a short drive from the resort beaches. Here’s exactly how it works with kids, which course fits which age, and what to book before you go.

Forest Adventure Onna at a Glance (Quick Answer)

Forest Adventure in Onna is an outdoor treetop zipline and rope course in central Okinawa with two options: the easy Canopy Course for kids from about 110 cm tall (roughly age 6+), and the harder Adventure Course for anyone 140 cm and up. Expect 1.5–2 hours in the trees, ziplines over the forest, and a continuous safety harness. Advance reservation is required, and it runs rain or shine unless there’s a storm.

What Forest Adventure Actually Is

Forest Adventure is a French-born “parc aventure” chain with parks all over Japan, including one in Onna, Okinawa. Kids clip into a harness and move through platforms built into living trees.

Between platforms there are ziplines, net bridges, log swings, and Tarzan-style jumps into a cargo net. It’s genuinely physical — not a padded playground.

The key safety feature: a continuous belay system. Once you clip in at the start, the carabiners can’t both come off at the same time, so kids are attached to a cable for the entire course.

If you’ve done our Saga day out at Forest Adventure Yoshinogari, the format is the same — this is the tropical, ocean-view version.

Canopy Course vs Adventure Course: Which One for Your Kids?

This is the decision that trips families up, because siblings often can’t do the same course. The dividing line is height, not age.

Canopy Course — gentle, lower to the ground, kids from ~110 cm. A parent can walk underneath and spot them.
Adventure Course — higher, longer ziplines, self-managed clips, 140 cm minimum. Better for confident older kids, teens, and adults.

If your child is under 140 cm, they’ll be on the Canopy Course and an adult usually needs to accompany younger ones. Measure at home before you book so nobody’s disappointed at the gate.

Course	Price	Min. height	Rough age	Duration	Best for
Canopy Course	~¥2,600	110 cm	6–10	~60–90 min	First-timers, younger kids (adult accompanies)
Adventure Course	~¥3,800	140 cm	10+ & teens	~90–120 min	Confident older kids, teens, thrill-seeking parents

Live prices and opening times: Adventure Course ~¥3,800; Canopy Course ~¥2,600 (reservation required), open 9:00-17:00 (advance reservation required; last start varies by season). Suggested age range is 6+.

For a mixed-age crew, this pairs well with the other high-energy options in our things to do in Okinawa with kids roundup, and it’s a genuine hit with older kids — see our Okinawa with teenagers guide for pairing it with other beyond-the-aquarium days.

Booking and Tickets

Forest Adventure runs on advance reservations by time slot — you can’t reliably just show up, especially in summer and on weekends. Book your slot online before you leave the hotel.

Reservations are usually made on the official Forest Adventure site. If you’d rather bundle it with other Okinawa activities on one account, browse family experiences and tickets on Klook Okinawa and reserve alongside the aquarium or a glass-bottom boat.

Turn up 15–20 minutes early for the safety briefing and harness fitting. Latecomers can lose their slot.

Getting There

Forest Adventure in Onna is in central Okinawa, near the Onna resort strip and Cape Maeda. The realistic way to reach it with kids is a rental car — bus access is impractical for a treetop park in the hills.

If you haven’t sorted wheels yet, our getting around Okinawa guide covers rental cars, car seats, and the Yui Rail. Parking at the park is Free.

Because it’s smack in the middle of the island, it slots neatly into a Central Okinawa day. See our Chatan, Yomitan & Onna family guide for what to pair it with — American Village lunch, a pottery village, or a beach afternoon.

What to Wear and Bring

This is an outdoor forest course, so kit matters more than at an indoor attraction.

Closed-toe shoes — sneakers required; sandals and Crocs are usually refused.
Athletic clothes that can get dirty; long shorts or leggings help under the harness.
Gloves — thin grip gloves save little hands on the cables (sometimes sold on site).
Water and a hat — the canopy shades you, but Okinawa humidity is real.
Bug spray — you’re in actual woods.

Sun still filters through the trees, so reef-safe rules from the beach carry over — our sun safety and reef-safe sunscreen guide covers what to pack for Okinawa kids.

Weather and Rainy-Day Reality

Forest Adventure generally runs in light rain — you’ll get muddy and it’s part of the fun. It closes for thunderstorms, strong wind, and typhoons for obvious safety reasons.

Check the forecast and the park’s status the morning of. During Okinawa’s wet stretch, keep a backup plan handy — our Okinawa rainy season guide lists indoor swaps if the trees are off-limits.

Is It Worth It With Kids? Our Honest Take

Yes — for the right ages. Kids who are physically confident and at least 110 cm come off it buzzing, and it burns hours of energy that beach days sometimes don’t.

Under-6s and very cautious kids may find it frustrating; there’s no toddler version. If your youngest can’t join, plan a nearby beach or park so one parent can tag out.

Book a morning slot to beat the afternoon heat, and pair it with a shaded lunch and a swim afterward for a near-perfect Okinawa family day.

Frequently Asked Questions

What’s the minimum age for Forest Adventure in Onna?

There’s no strict age number — it goes by height. The Canopy Course starts around 110 cm (typically age 6+), and the Adventure Course needs 140 cm. Measure your child before booking, since siblings of different heights often end up on different courses.

Do I need to book in advance?

Yes. Forest Adventure runs on timed reservations, and summer and weekend slots fill up. Reserve online before you go and arrive 15–20 minutes early for the harness fitting and safety briefing.

How long does it take?

Plan for about 1.5 to 2 hours in the trees, plus check-in and gear-up time. The Adventure Course runs longer than the Canopy Course. Budget half a day once you add travel.

Does it run in the rain?

Usually yes in light rain — expect mud and enjoy it. It closes for thunderstorms, high winds, and typhoons. Check the park’s status the morning of your visit, especially during rainy season.

Can parents go with young kids?

On the Canopy Course an adult typically accompanies younger children and can spot from below or alongside. On the Adventure Course everyone manages their own clips, so it suits confident older kids, teens, and adults.

How do we get there without a car?

Realistically, you need a rental car. The park is in the Onna hills with poor public-transport access. It fits naturally into a central Okinawa driving day around Chatan, Yomitan, and Onna.

What should kids wear?

Closed-toe sneakers (no sandals or Crocs), athletic clothes that can get dirty, and optional grip gloves. Bring water, a hat, and bug spray. Sunscreen still matters even under the canopy.

Is it too scary for first-timers?

The Canopy Course is designed for beginners and stays lower to the ground, so nervous kids can build confidence. The Adventure Course is higher with longer ziplines and is better once a child already enjoys heights.
