Siam Amazing Park: the wave-pool day, priced and timed.

One park, five zones, one ticket

The park splits into Water World plus four ride zones — Xtreme World for the big coasters (Vortex, Boomerang, the Giant Drop), Adventure World, Family World and Small World for the under-130 crowd. The day pass covers all of them, which is the practical difference from pricing up Dream World, where the extras sit outside most tickets. Note the tier logic: it's height, not age — the park's own FAQ draws the adult line at 130 cm because that's where the ride manufacturers draw theirs. A tall eight-year-old pays adult price and rides the adult rides; a small ten-year-old doesn't, on both counts.

The wave pool, and the name change worth knowing

The wave pool is the reason this park is on the list at all — a Guinness-certified giant the park calls the world's largest, wide enough that the far end feels like an actual beach when the swell machine runs. If you knew this place from an older guidebook, it was Siam Park City, and Thais still say Suan Siam; taxi drivers respond to the old name faster than the new one. Same park, same address on Suan Siam Road, renamed in its 2019 rebrand.

Honest expectation-setting: this is a park running since 1980, and it reads that way — some corners are worn, and on any given week a ride or two may be down. Check the park's own channels for current ride status the week you go; don't assume every headline ride runs daily. The water side is the consistent half, and it's the half you're going for.

With kids, practically

The 101–130 cm ticket at ฿850 covers a child's whole realistic day: Small World, Family World and the shallow ends of Water World. Under-100s swim free, which makes this the cheapest big family day out of Bangkok's three big parks. Bring swim gear that follows the park's rules (proper swimwear, not street clothes — their FAQ is specific), rent a locker in Water World (the park runs a locker service), and plan the water half for the morning before the afternoon sun peaks.

Getting there

The park sits at 203 Suan Siam Road, Khan Na Yao — the east side of Bangkok, past the Ram Inthra corridor. Since late 2023 the MRT Pink Line monorail runs along Ram Inthra: get off at Nopparat station (PK26), the stop named for the hospital nearby, and it's a short taxi or motorbike-taxi hop down Suan Siam Road to the gate. A ride-hail straight from central Bangkok runs 40–70 minutes depending on the expressway. Pair it with our Bangkok with kids plan as the full-day slot — with an 18:00 close and the water side best before the afternoon storm window, arrive at opening.

Quick answers

How much is Siam Amazing Park in 2026?

The official standard day pass is ฿1,000 for anyone above 130 cm and ฿850 for 101–130 cm; children under 100 cm enter free. Online seasonal promotions run cheaper — check the park's official ticket site before paying gate price.

What are the opening hours?

Daily, 10:00–18:00, per the park's own pages.

Is Siam Amazing Park the same as Siam Park City?

Yes — same park in Khan Na Yao, renamed from Siam Park City (Suan Siam) in 2019. Locals and taxi drivers still use the old names.

Which is better with kids, Siam Amazing Park or Dream World?

Water versus rides. Siam Amazing wins on a hot day and on price for small children (free under 100 cm, one ticket covers everything); Dream World wins for coaster-hungry kids over 120 cm and for Snow Town. Both are full-day trips in opposite directions — don't try to combine them.
