Houston Water Parks: A Side-by-Side Guide to Every Option

Houston water parks open in early April and run hard through September, and the metro now has more options than any other Texas market — six legitimate water parks within 90 minutes of downtown plus the Great Wolf Lodge indoor park in Webster. This is the practical Houston water parks guide: who runs the best slides, who's the cheapest, who's the closest, and what each one is actually known for. See the entertainment hub for the rest of the summer-weekend playbook.

The Houston-area water park lineup: Big Rivers Waterpark in New Caney, Typhoon Texas in Katy, Schlitterbahn in Galveston, Hawaiian Falls in The Colony (closed; the closest Hawaiian Falls is now a 90-minute drive north), Splashway in Sheridan, Six Flags Hurricane Harbor Splashtown in Spring, and the indoor Great Wolf Lodge in Webster. The day-pass big-name parks are Splashtown, Typhoon Texas, and Schlitterbahn. The day-trip standout is Splashway. The under-the-radar pick for families is Big Rivers.

Six Flags Hurricane Harbor Splashtown (Spring)

Address: 21300 I-45 North, Spring. Drive: 25 minutes from downtown, the closest big-name water park to inner-loop Houston. The Hurricane Harbor Splashtown listing has the full venue card. The Spring area sits just north of FM 1960 along I-45.

Known for: the legacy Houston water park — it operated as SplashTown for decades before Six Flags rebranded it. 28 slides, the Tornado funnel ride, the Wahoo Racer mat-slide six-lane race, and the Lone Star Lagoon wave pool. The Castaway Cove lazy river is the most-popular family ride.

Hours: weekends only from early May (typically May 2 opening weekend), then daily June through August, then weekends only through Labor Day. Operating hours 11 a.m. to 7 p.m. most days.

Pricing: a 2026 season pass ranges $65-$125 depending on tier (Bronze, Silver, Gold, Diamond, Diamond Elite). Single-day tickets run $40-$60 online, more at the gate. Free for kids under 2. Parking is $30. The Diamond pass — at around $125 — pays back in three visits and includes Hurricane Harbor Splashtown plus several other Six Flags water parks nationwide.

Typhoon Texas (Katy)

Address: 555 Katy Fort Bend Road, Katy. Drive: 40 minutes from downtown. The Katy area page has the broader suburb context.

Known for: the highest-rated water park in the Houston metro by most family-magazine roundups. 33 water slides, a sand beach wave pool, the Tropical Splash kids zone, the BamBoo Chute lazy river, and live summer concerts. The Texas Twister is the marquee thrill slide. The cabanas (rentable, expensive) are the move for groups.

Hours: open weekends only April 11 to mid-May, daily Memorial Day through early August, then weekends only through September 20. 10:30 a.m. to 7 p.m. weekday hours, 10 a.m. to 8 p.m. weekends.

Pricing: any-day tickets run $39.99 to $59.99 depending on date, $64.99 for a season pass. Free for kids under 2. Parking is $20 in the standard lot, $40 in the preferred lot. Save money by buying online at least 24 hours ahead. Typhoon Texas also runs daycare-style camps in summer ($75-$95 per kid per day, includes admission and lunch).

Schlitterbahn (Galveston)

Address: 2026 Lockheed Road, Galveston. Drive: 50 minutes from downtown.

Known for: the Texas water park name. The Galveston location runs both an indoor and an outdoor park section — the indoor section (the Massiv) is climate-controlled and operates earlier in the season. The Boogie Bahn surf machine is one of the few stand-up surf rides in Texas. Master Blaster uphill water coasters and the Torrent River wave river round out the marquee attractions.

Hours: opens for the 2026 season on May 2 (weekends only), then daily Memorial Day through mid-August, then weekends only through late September. The indoor section opens at 10 a.m.; the outdoor section opens at 11 a.m. and runs until 7 p.m. Closing time is 8 p.m. on summer Saturdays.

Pricing: 2026 Gold Season Pass is $89 (a deal — it pays back in two visits and includes all Schlitterbahn parks). Single-day tickets run $50-$65. Free for kids under 3. Parking is $15. The Schlitterbahn cabanas are the best-value cabanas of any Houston-area park.

Big Rivers Waterpark (New Caney)

Address: 23101 Highway 242, New Caney. Drive: 35 minutes from downtown (north on I-45, east on TX-242).

Known for: the dual-park concept. Big Rivers combines a mid-size water park (3 slide towers, a 850-foot lazy river, a wave pool, a beach pool) with a separate dry adventures park (an inflatable course, a 30-foot rope course, zip lines, ax-throwing, a corn maze, an alligator exhibit, and a petting zoo). One ticket covers both. The closest thing the Houston market has to a one-day amusement-park-plus-water-park combo.

Hours: Spring Adventure days run select weekends in March (water attractions closed). Full park (water + adventures) operates April 3 through September 30. Hours 11 a.m. to 7 p.m.

Pricing: single-day tickets are $19.99 during March Spring Adventure days (no water access) and $44.99 from April 3 through September 30 (full access). Season passes are $99.99. Free for kids 2 and under. Parking is $15. Big Rivers is the deepest discount play for families with multiple kids.

Splashway Water Park (Sheridan)

Address: 5211 Main Street, Sheridan. Drive: 1 hour 30 minutes from downtown (west on I-10, south on US-90A).

Known for: the destination-day pick. Splashway is family-owned, smaller than Typhoon Texas, and consistently rated the friendliest water park staff in Texas. The Castaway Cove lazy river, the Boomerango speed slide, and the Tahiti Tube body slide are the standouts. The park sits next to a 200-pad campground (Splashway Campground), which is the move for two-day stays.

Hours: weekends only May through Memorial Day, daily Memorial Day through August 17, then weekends only through Labor Day. 10 a.m. to 7 p.m. operating hours.

Pricing: single-day tickets are $36-$46 online. Season passes run $99. Free for kids 3 and under. Parking is free. Tent camping at the adjacent campground is $35-$55 per night. The total cost for a Splashway weekend (two days of park, a night of camping) often runs less than a single day at Typhoon Texas with parking.

Great Wolf Lodge Webster — the indoor option

Address: 600 Great Wolf Lane, Webster. Drive: 35 minutes from downtown. Indoor, 84-degree year-round.

Known for: the indoor water park hotel. 92,000 square feet of indoor water park kept at a warm 84 degrees year-round, included with every overnight stay. Howlin' Tornado funnel, Wolf Tail trap-door drop, River Canyon Run family raft, the lazy river, and a toddler-zone tree house make it the most range-accommodating water park in the metro.

Hours: 9 a.m. to 9 p.m. Sunday-Thursday, 9 a.m. to 10 p.m. Friday-Saturday.

Pricing: water park access is included with overnight stays — no separate ticket. Day passes are sold when capacity allows ($60-$85 per person). Family Suite rates run $250-$650 per night depending on season.

Water park planning tips

• Buy tickets online at least 24 hours ahead. Every park except Big Rivers charges $5-$15 more at the gate.
• Arrive 15 minutes before park open. The first 90 minutes have the shortest lines for slide towers; the lazy river never has a line.
• Pack reef-safe sunscreen, water shoes, and a refillable water bottle. Most parks ban glass and outside food but allow sealed water bottles and small snacks.
• Rent a cabana for groups of 4+. The math works out cheaper than buying 4 separate food and shade purchases across a 7-hour day.
• Schlitterbahn allows outside food in coolers (no glass). Typhoon Texas, Splashtown, and Big Rivers do not. Splashway permits outside food in limited coolers.
• All Houston-area water parks require kids under 48 inches to wear provided life vests. Free at all parks.
• Save the marquee thrill slide for the last hour. Lines drop 60-80% in the final 90 minutes before close.

Which water park to pick

• Closest to inner-loop Houston: Splashtown (Spring) — 25 minutes
• Highest-rated by Houston families: Typhoon Texas (Katy) — 40 minutes
• Best Texas brand-name and surf machine: Schlitterbahn (Galveston) — 50 minutes
• Best value plus dry-park combo: Big Rivers (New Caney) — 35 minutes
• Best two-day destination with camping: Splashway (Sheridan) — 1 hour 30 minutes
• Best year-round option (rain or 110 degrees): Great Wolf Lodge (Webster) — 35 minutes

Most Houston families end up picking two and rotating: one big-name day at Typhoon Texas or Schlitterbahn, plus one budget day at Splashtown or Big Rivers. For the rest of the family weekend playbook, see the Hermann Park visitor guide and the Houston Zoo visitor guide.
