Adventureland’s gates open at 10 a.m. on every day the park runs, but closing time is the part that trips people up: it shifts week to week depending on the season, the day, and whether Adventure Bay is open too. That’s why “Adventureland hours” is one of the most-searched questions about the Altoona, Iowa theme park.
This guide breaks down the full 2026 operating calendar, including exactly which weeks the park runs daily versus weekends-only, when Adventure Bay’s schedule diverges from the main gate, and every other detail you need to plan a visit: ticket and season pass pricing, parking, the ride lineup, on-site camping, and the bag policy.
Quick Answer
Adventureland’s gates typically open at 10 a.m. on every operating day, with closing time ranging from around 6 p.m. during spring and fall weekends to roughly 9 p.m. on peak summer days. For 2026, the park runs Friday through Monday only in May, daily from June through August 23, weekends-only through Labor Day (September 7), and then on a reduced schedule through Phantom Fall Fest in October. Adventure Bay water park follows a similar but slightly later calendar. Always check the official Adventureland hours and calendar page for the exact times on the day you’re planning to go, since specific hours shift year to year.
Adventureland Hours: The Full 2026 Season Calendar
Adventureland kicked off its 2026 season on Saturday, May 16, open from 10 a.m. to 6 p.m. For the rest of May, the theme park operates Friday through Monday only, giving early-season visitors a long weekend window rather than a full seven-day schedule.
Once June arrives, Adventureland switches to daily operation and holds that schedule through August 23. From there it reverts to a weekends-and-holidays pattern through Labor Day (September 7), then continues on a lighter fall schedule through Phantom Fall Fest in October before closing for the winter.
Daily hours follow the same seasonal logic: gates generally open at 10 a.m. year-round, while closing time is shortest on spring and fall weekend days (often around 6 p.m.) and stretches later into the evening — up to around 9 p.m. — on peak summer days and during special events. Because exact daily open and close times are published on a rolling basis, cross-check the official operating hours calendar before you leave home, especially if you’re visiting during a shoulder-season week.
Adventure Bay Water Park Hours
Adventure Bay, the water park included with regular admission, opens about a week after the main gate — in 2026 it opened Saturday, May 23, from 11 a.m. to 7 p.m. Its May schedule runs Saturday through Monday only, then shifts to daily operation alongside the theme park through late August before dropping back to weekends for the fall shoulder season.
Because Adventure Bay is weather-dependent, its hours and open days can change on short notice even within its posted calendar — a cool or rainy forecast sometimes means a later opening or earlier closing than the theme park next door. In 2026, Adventureland also added Neon Nights, a Friday-and-Saturday evening event at Adventure Bay from 7 p.m. to 10 p.m. running July 10 through August 15.

Tickets, Prices & Season Passes
Adventureland sells admission in a few tiers: single-day gate tickets, discounted advance-purchase tickets online, and season passes for repeat visitors. Advance online pricing is almost always cheaper than paying at the gate, and local credit unions and grocery partners in the Des Moines area frequently sell discounted tickets as well.
Season passes are tiered (entry-level, mid, and premium levels), with higher tiers adding perks like free or discounted parking, bring-a-friend tickets, and discounts on food and merchandise. Because prices and promotions change by season, use the official Adventureland Resort site for current rates rather than relying on cached prices elsewhere online.
Parking & Getting There
Adventureland sits at 3200 Adventureland Drive, Altoona, IA 50009, just off Interstate 80 a few minutes northeast of downtown Des Moines, making it an easy day trip from most of central Iowa.
General admission tickets do not automatically include a parking discount, but many season pass tiers do — ranging from a percentage discount on daily parking up to free parking for the top pass tier. Check the official directions and parking page on the Adventureland Resort site for current parking rates and the latest driving directions.
The Ride Lineup
Adventureland’s seven roller coasters mix wood and steel. Tornado, a wooden out-and-back coaster designed by William Cobb and built by the Frontier Construction Company, debuted on July 4, 1978 and reaches about 93 feet tall, hits roughly 58 mph, and runs about 2,850 feet of track along the shore of a small lake; in 2024 the American Coaster Enthusiasts named it a Coaster Landmark.
Other wooden entries include Outlaw and the fully enclosed Underground, both built by Custom Coasters International, with Underground threading its train through a dark, covered structure rather than open air. On the steel side, Monster is a Gerstlauer Infinity model that was the first of its kind built in the United States when it opened in 2016, while Phoenix is a Maurer spinning coaster and Dragon Slayer is an S&S 4D Free Spin. The park rounds out its coaster lineup with Flying Viking, a smaller Zamperla family coaster, plus dozens of additional family, thrill, and kids’ rides, including the Space Shot drop tower and the Storm Chaser swing ride.
Camping at Adventureland Resort
Adventureland operates its own on-site campground, Adventureland Campground, with full-hookup RV sites (including big-rig-friendly, pull-through spots), tent camping, modern shower and restroom facilities, and a swimming pool, positioning the property as a resort destination rather than just a single-day park.
The campground generally runs from May through the end of October, matching the park’s own operating season, and season pass holders can receive camping discounts. Book directly through the official Adventureland Campground page on the Adventureland Resort site for current site availability and rates.
Bag Policy & Park Rules
Adventureland allows one bag per guest, generally capped around 15 x 15 x 15 inches, and bags go through a physical inspection at the front gate rather than requiring a clear-bag-only policy. Standard backpacks, totes, purses, and diaper bags are permitted; diaper and medical bags get reasonable exceptions to the size rule.
Guests may bring in sealed, unopened bottled water or sports drinks, and empty refillable bottles can be filled at bottle-filling stations inside the park. Outside food and coolers are generally not allowed past the gate, though the park makes exceptions for documented medical and dietary needs — check the official rules page on the Adventureland Resort site for the current, complete list before you pack.
