Taiwan Water Parks by Age 3–12: Maraman, Leofoo, Janfusun (2026)

110 centimeters. That number decides which rides your kid actually gets on.

I've taken both my kids through several Taiwan water parks. Every time, before I buy tickets, I measure them. Why so picky? Because rides don't care about age. They only care about height. The lazy river won't seat anyone under 70 cm. The big slides usually need 130 cm. If your kid lands in the middle, half of that full-price ticket is wasted.

In this guide I'll lay out three of Taiwan's domestic water parks side by side: Maraman Water Park (馬拉灣) in Houli, Taichung; Leofoo Water Park (六福水樂園) in Guanxi, Hsinchu; and Janfusun Water Park (劍湖山) in Gukeng, Yunlin. I'll cover three age bands: 0–3, 4–7, and 8–12. The single most important sentence first.

Measure your kid before you buy the ticket.

Three Things to Check Before You Book by Age

"Age band" isn't really about age. It's about three things.

First, height. Almost every ride uses height, not age, as the gate. Common thresholds are 70, 100, 110, 130, and 140 cm. My younger one was once 3 cm short of the slide cutoff. She cried at the gate for ten minutes.

Second, water depth. Toddler pools typically run about 30 cm deep. But the outer edge of the wave pool runs deeper than an adult's waist. Your kid plays happily in the shallow end. Two steps the wrong way and you've got a problem. Don't take your eyes off them.

Third, sun and nap time. Water parks have almost no shade. UV is the silent enemy. Kids splash for half a day and crash. My routine is fixed: play in the morning, retreat at noon, buy an afternoon ticket if needed to skip the midday sun.

This is the height-threshold table I check before every visit:

Height threshold	Approx. age	Roughly what's playable
Under 70 cm	About 0–2	Shallow toddler pool only
70–110 cm	About 2–7	Lazy river (life vest + adult companion), wave pool shallow edge
110–130 cm	About 6–9	Mid-size slides, rainbow slide, splash play structures
Over 130 cm	About 9+	Big slides and two-person rafts mostly unlocked

Ages 0–3: Toddler Pool Only, Big Rides All Blocked

The bottom line first. For kids 0 to 3, the toddler pool is essentially all you get.

Under 3 years old or under 100 cm height — all three parks let your child in for free. But free doesn't mean fun. Anyone under 70 cm can't ride the lazy river at all, never mind the wave pool or any slide. The realistic playspace for this age is the kids' splash zone.

Maraman has "Sima Lake" (思瑪湖) with zones graded by toddler height. Leofoo Water Park has "Water Maze" (水迷宮) at 30 cm depth with a sandy pool beside it. Janfusun has rows of water cannons and tipping buckets. When my younger one was 2, the Leofoo water maze ate an entire afternoon.

She refused to leave.

A realistic note first. Water parks are not great value for 0–3 because there's only one small area they can use. Ticket money, full day in the sun, lower ROI than you'd think. If you just want toddler water play without UV exposure, indoor family parks are safer. Something like KKday's Taoyuan Qiaohu Dreamland family bundle is indoor and works on rainy days.

Ages 4–7: The Awkward 100–120 cm Window

Ages 4 to 7 is the most awkward stretch.

Most kids this age fall between 100 and 120 cm, and they're stuck in the middle: the toddler pool feels babyish, but the big slides are still off-limits. The unlock list does start growing, though.

The lazy river accepts 70 to 110 cm with a life vest and adult company throughout. The wave pool requires a parent for under 110 cm. Maraman's "Aqiuwan" (阿酋彎) has a rainbow slide for kids between 110 and 150 cm. Water jets and tipping buckets everywhere. My older one at 6 spent hours there and never got bored.

But the thrill slides still gate them out. Maraman's Speed Warrior slide blocks under 130 cm. The Wizard Raft is even higher, requiring 135 cm. Leofoo's Poseidon Raft also starts at 130 cm. The time my older one measured at 115 cm, she watched bigger kids fly down slides while she circled the lazy river.

I remember the look on her face.

For this age, I'd pick a park with lots of splash structures and a good lazy river. Janfusun's single ticket covers both water and land sections, and the splash zone is big. Klook's Janfusun one-day ticket often runs at a discount, so the math works best here.

Ages 8–12: Slides Unlock, Stamina Becomes the Limit

Ages 8 to 12 is when the water park actually opens up for your kid.

Most kids at this age clear 120 cm, and the 130-to-140 cm rides start unlocking one by one. Maraman's Speed Warrior has five slides. Leofoo's Big Whirlpool requires 140 cm plus swimming ability. The Poseidon Raft and Dark Slide start at 130 cm. The playable list expands fast.

But height isn't the constraint anymore. Stamina and nerve are. After each slide run, kids haul their own tube up the stairs to queue again. When my older one was 10, by 3 PM her legs were done.

One afternoon and they're toast.

Nerve also matters. Leofoo Water Park had a guest fall from a slide in 2024.

High-speed slides require correct posture every single time.

No matter how much your kid complains, don't let them ride loose.

This age fits parks with high ride density. Leofoo Water Park combined with the adjacent Leofoo Village land park gives one ticket access to all the thrill rides. Klook's Leofoo Village two-person bundle suits one adult plus one older child going hard together.

Maraman, Leofoo, and Janfusun — Age-Band Comparison Table

After walking through all three age groups, here's the three parks in one table to check before booking:

Park	Age 0–3	Age 4–7	Age 8–12	2026 season	Reference ticket price
Maraman (Houli, Taichung)	Sima Lake graded play zones	Aqiuwan rainbow slide	Speed Warrior, Wizard Raft	Opened 4/3, daily through summer	Adult list NT$1,300 (~US$40), commonly discounted to NT$850–899 (~US$26–28); moonlight ticket NT$499 (~US$15), entry after 5 PM
Leofoo Water Park (Guanxi, Hsinchu)	Water Maze, sandy pool	Lazy river, wave pool shallow end	Big Whirlpool, Poseidon Raft	Daily 6/19–8/30; weekends and public holidays in September	Adult NT$799 (~US$25), student NT$599 (~US$19), child NT$499 (~US$15), toddler NT$399 (~US$12); afternoon ticket NT$399 (~US$12), entry after 1 PM
Janfusun (Gukeng, Yunlin)	Splash play zone	Snoopy lazy river, air mat slide	Big Bowl, Tornado	Water rides 6/19–9/6	One ticket covers water and land; list NT$1,199 (~US$37), commonly discounted to NT$599–699 (~US$19–22)

How to read this. Maraman's Sima Lake has the most granular age zoning, covering toddler through pre-school. Leofoo's Water Maze plus sandy pool is the 0–3 killer combo. Janfusun's single-ticket water-and-land access gives the best ROI for school-age kids.

Two dates worth writing down. After 8/30 Leofoo Water Park runs weekends and public holidays only, and Janfusun's water rides shut on 9/6. If you're squeezing in a trip at the tail of summer, the window is tighter than it looks.

Prices move, and each park's standing discounts move with the promo calendar. Compare the live numbers across the booking platforms first, then confirm against the official site before you travel.

Swimwear Rules Differ by Park, and Wrong Gear Means No Entry

I learned this one the hard way.

All 3 parks require proper swimwear. It isn't a suggestion — wrong gear and you don't get in the water. But the 3 parks care about different things, so here's each one.

Maraman is the strictest, and the swim cap is non-negotiable. The official wording is blunt: proper swimwear in water-resistant fabric, swim cap required. Board shorts are fine, but no buttons or zippers. Cover-ups are allowed if the fabric is water-resistant. Rash guards can go in the water. The HOSA hut at the entrance sells swimwear if you forgot yours, at gate prices.

Leofoo checks fabric, not style. To ride a slide or enter the play structures: swim cap plus swimwear, and cotton or knit fabrics cannot go in the water at all. No metal, buckles or zippers on any garment. Cover-ups are fine as long as they aren't water-absorbent cotton, but the Big Whirlpool, Speed Flying Fish and Dark Slide require taking them off first, because a soaked cover-up can wrap over your head. Accessories are banned outright on rides: swim rings, goggles, necklaces, rings, watches, bracelets, earrings, waterproof phone pouches, GoPros.

Janfusun says it in one line, and it means the same thing. Before entering the water, put on swimwear and a swim cap, and check your clothing for cotton content and any hard fittings like buttons or zippers.

Two more things on the kid side.

Life vests. Maraman rents them at NT$200 (~US$6.2), of which NT$100 (~US$3.1) is a refundable deposit. The smallest rental size fits down to about 15 kg. Below that, bring your own, and it cannot be an inflatable one because the park won't accept those.

My younger one once wore a cotton sun jacket in and got turned back at the changing room door.

She cried about it for a while.

Pack swimwear, swim cap and a water-resistant cover-up into the same bag before you leave the house. Whatever is missing, you buy at gate prices.

Lockers belong in the budget too. Leofoo's run from NT$20 (~US$0.6) to NT$400 (~US$12), and with kids I always take the big one so diapers, spare clothes and a swim ring all fit in one trip.

On-Site Logistics with Kids: Changing Tables, Feeding, Naps

Tickets bought, heights checked, swimwear cleared. The rest happens inside the park, and these are the points that trip up parents the most.

Locate the changing tables first. Before you go, check the official site for family bathrooms and changing stations. Water parks are huge. The moment your kid needs a diaper change and you're on the opposite end of the park, it gets messy fast.

Don't push through feeding. Kids playing in water get hungry fast, and on-site food is expensive. Pack simple snacks, but verify each park's outside-food policy first. My younger one hits hunger and melts down right in line.

Schedule the nap. Water play burns serious energy. Around 1 or 2 PM, kids drop hard. If you want two days, stay at a hotel next to the park. Trip.com's weekly Friday Buy-One-Get-One on selected tickets and experiences sometimes throws in a free water park ticket when two adults travel together.

Where to Buy Tickets the Smart Way

Now the money side. The three parks price differently.

Maraman runs a moonlight ticket: enter after 5 PM for NT$499 (~US$15). Leofoo Water Park has an afternoon ticket at NT$399 (~US$12) for entry after 1 PM, which is about right for a half-day with a toddler. Janfusun uses one ticket for water and land, and also offers an afternoon option.

Leofoo has stacked its discounts this summer, and they all expire on the same date. The 3 still running:

Deal	Condition	Water park price	Expires
Outfit discount	Wear flip-flops or a sleeveless top when buying at the gate	NT$450 (~US$14)	8/30, extended to selected September holidays
Afternoon ticket	Enter after 1 PM, no eligibility check	NT$399 (~US$12)	8/30
Hawaiian shirt combo	Wear a Hawaiian shirt, floral top or floral dress	Water + land combo NT$999 (~US$31)	8/30

One more thing worth flagging. Leofoo's earlier lucky-digit promo, the one keyed to ID numbers containing 5, 8 or 0, ended on 7/31. Plenty of guides still list it. Showing up to claim it is a wasted trip to the counter.

For platforms, Klook, KKday, and Trip.com all sell these tickets. Prices track the official sites and usually undercut on-site prices by a small margin. My habit is to compare all three platforms before checkout, then layer on whatever credit-card bonus is currently active.

For a one-stop scan of live ticket prices and codes across all three parks, the 1stCoupon Klook deals page handles that. One reminder. Water park tickets are usually date-bound or have short validity windows. Confirm the weather and your kid's status before you tap purchase.

FAQ

Q1: Are kids under 3 really free? Do I need ID? All three parks waive entry for kids under 3 or under a certain height threshold, with minor variations between parks. Bring your child's passport or any document showing their date of birth. If your kid is right at the cutoff, staff will measure on the spot.

Q2: My kid is just a couple cm short of the height limit. Any workaround? None. Height limits are safety rules. Staff will pull a kid from the queue mid-line if they fall short. The pragmatic move is using the comparison table to pick a park that offers more in the splash and lazy river zones, so the ticket money lands on rides they can actually use.

Q3: Do my kids need to know how to swim? For lazy rivers, wave pools, and toddler splash zones, no. Life vest plus adult supervision is enough. Some big slides do require swimming ability — Leofoo's Big Whirlpool, for example. Those rides are gated at age 8+ anyway.

Q4: Can my kid wear a regular T-shirt or a sun jacket in the water? No. All 3 parks block cotton. Leofoo states that cotton and knit fabrics cannot enter the water, Janfusun asks you to check for cotton content before getting in, and Maraman requires cover-ups to be water-resistant. If your kid burns easily, switch to a rash guard — all 3 parks allow those. Maraman also requires a swim cap on every ride, so pack one in the kid's size.

Q5: Do water parks open in the rain? Light rain typically doesn't stop operations. Thunder or heavy rain triggers temporary ride closures. This is part of why indoor family parks make a useful backup plan for toddlers. Check the forecast the night before.

Q6: Which summer month is least crowded? The entire summer is peak season. Relatively better windows are weekdays and the first hour after opening. Hit the most popular slides right at open. Crowds peak around noon, which conveniently lines up with kids needing a nap.
