"Harpers Ferry water park" and "Harpers Ferry Adventure Center" are two of the most searched phrases about the area, and they get mixed up constantly. They are different places run by different companies, in different states, and neither is in historic Harpers Ferry, West Virginia. This independent guide sorts out which is which, what each offers, the rules that matter, and how they compare with a river trip. It's part of our things to do in Harpers Ferry guide.

Is there a water park in Harpers Ferry?
Yes. The Harpers Ferry Waterpark is a floating inflatable park on what its site calls a "scenic private quarry," with slides, floating obstacles, jump platforms and ninja-style challenges. Its site says it is "a part of the River Riders family" and lists River Riders' address, 408 Alstadts Hill Road, Harpers Ferry, WV, and phone, 304-535-2663. For 2026, it says it "more than doubled the size of the park."
The Harpers Ferry Waterpark is an inflatable course on open water, not a pool-style park with concrete slides, and it is not part of Harpers Ferry National Historical Park. It's a private summer attraction, and you'll drive there.
Is Harpers Ferry Adventure Center in Harpers Ferry, WV?
No. Harpers Ferry Adventure Center's main location is in Virginia: 37410 Adventure Center Lane, Purcellville, VA 20132. Its directions page sends you along US 340 across the Potomac River bridge, then tells you to make the first left immediately after the bridge, before the light, and go through the gated entrance. That puts it on the Virginia bank of the Potomac, across the water from Lower Town. Its own site stresses that the main address is Purcellville, VA, not Harpers Ferry, WV.
One exception: Harpers Ferry Adventure Center's flat-water tubing checks in at 150 Millville Road, Harpers Ferry, WV 25425, which its site says is "NOT at our main location." Enter each address in your GPS exactly as the company gives it.
Harpers Ferry Brewing is on the same lane, at 37412 Adventure Center Lane. Harpers Ferry Adventure Center says its wristband holders get 10% off there.
What can you do at Harpers Ferry Adventure Center?
Harpers Ferry Adventure Center runs river trips and land adventures from its Virginia base. Its site lists tubing, whitewater rafting, kayaking, a zipline, a ropes course and camping. Its own "Know Before You Go" page sets these minimums and typical times:
| Activity | Minimum (Harpers Ferry Adventure Center) | Typical time |
|---|---|---|
| Flat-water tubing | 5 years and 40 lb | 1–2 hours on the water |
| Whitewater tubing | 12 years | 1.5–2.5 hours |
| Whitewater rafting | 5 years and 50 lb | 2–3 hours |
| Whitewater kayaking / duckies | 12 years | Check with the outfitter |
| Zipline | 7 years and 70 lb; 250 lb maximum | 1.5–2 hours |
| Ropes course | 5 years, 50 lb and 3 ft tall | About 2 hours |
Other rules worth knowing before you book:
- Arrive 30 minutes early for waivers and gear. Late arrivals can be cancelled without a refund.
- Pay at booking. Reservations are required for guided trips, with full payment due when you book.
- Rain or shine. Trips pause for thunderstorms, and the company can change trips, group sizes or minimum ages for water levels or weather.
- No pets, though service animals are welcome.
- Camping: campsites have no electricity, and reservations are required.
Peak season is June through August, when trips can sell out. As of November 2026 the company hadn't posted 2027 dates or prices, so check its booking page in spring.
What are the Harpers Ferry Waterpark rules?
The Harpers Ferry Waterpark's rules page is strict about age, height and swimming:
- Age and height: at least 5 years old and 45 inches tall. Some attractions have their own limits.
- Swimming: "Participants must be able to swim proficiently."
- Life jackets: everyone wears a secured, fitted life jacket at all times. The park has sizes from youth to adult XXXL. Your own Coast Guard-approved Type III jacket may be allowed, but staff can require the park's.
- Companions: ages 5 and 6 need a paying companion in the park with them. The rules say ages 7 to 14 need a companion on site, while the FAQ says anyone under 16 needs an adult on the property, so plan on an adult staying.
- Waivers: participants 18 and older sign their own; a guardian signs for anyone 17 and under and must be at check-in.
- Spectators: everyone on site needs a pass. A discounted non-participant pass is available.
Each session is 1.5 hours, and the park asks you to arrive 30 minutes before your slot. Go barefoot or wear grip socks, which are sold on site. Bring sunscreen, water and an ID. You can bring your own food and non-alcoholic drinks, though not into the water, and snacks, drinks and ice cream are sold there.
The waterpark closes only for thunder and lightning; rain and cool days don't close it. Its rules say there are no refunds within 3 days of your date, with a credit good for a year.
When is the waterpark open, and what are the hours?
River Riders' waterpark pass page lists the season as "Memorial Day through Labor Day," without a year. Neither the waterpark site nor River Riders had posted 2027 opening dates, session times or prices when we checked in November 2026, so check with the waterpark before you plan around it. Splash passes are sold by time slot on its booking page.
River Riders also sells a Waterpark Full Day Adventure Pass that pairs a 1.5-hour waterpark session with a 2-hour climb in its Aerial Adventure Park.
What is the River Riders Aerial Adventure Park?
The Aerial Adventure Park is River Riders' ropes course in the trees, which River Riders says has more than 100 challenge elements of varying difficulty. Climb time is two hours, and the weight range is 40 to 265 pounds. Its season pass runs May 1 to September 30. River Riders also sells separate zipline tours. In winter the same property runs Snow Riders snow tubing.
So if you want ropes and ziplines, you have two choices: River Riders in West Virginia or Harpers Ferry Adventure Center in Virginia.
How far are they from Lower Town Harpers Ferry?
Both are a drive from Lower Town, not a walk. Neither is inside Harpers Ferry National Historical Park, and the park shuttle runs only between the Visitor Center and Lower Town. From Harpers Ferry Adventure Center, you follow US 340 across the Shenandoah River into West Virginia to the park Visitor Center at the Harpers Ferry stoplight. River Riders is on Alstadts Hill Road on the West Virginia side. We haven't published drive times we couldn't confirm, so check your map app.
If you're pairing a waterpark or river day with Lower Town:
- Park at the Visitor Center, 171 Shoreline Drive, and ride the shuttle. NPS lots close 30 minutes after sunset.
- Pay the park fee only for the park part of your day. See our parking, fees and shuttle guide.
- Watch the footbridge closure. As of November 2026 the Potomac footbridge is closed; see the footbridge update.
Waterpark or river tubing: which should you choose?
Choose the waterpark for still water, lifeguards and a fixed 1.5-hour session, especially with kids who meet the 5-year, 45-inch rule. Choose river tubing for a longer float on the Shenandoah or Potomac, as long as the river is at a safe level. Our tubing and rafting guide compares all three outfitters.
| Harpers Ferry Waterpark | River tubing | |
|---|---|---|
| Where | Private quarry, 408 Alstadts Hill Rd, WV | Shenandoah or Potomac, depending on outfitter |
| Water | Still quarry water | Moving river, from flat water to class II–III |
| Time | 1.5-hour session | About 1–2.5 hours on the water (Harpers Ferry Adventure Center) |
| Minimum | Age 5, 45 in., proficient swimmer | From 5 years and 40 lb (flat water) to 12 years (whitewater) at Harpers Ferry Adventure Center |
| What cancels it | Thunder and lightning | High water: River Riders stops tubing at 6–10 ft and all river trips at 10+ ft |
| Life jacket | Required for everyone | Wear one, buckled, every time |
| Season | Memorial Day–Labor Day (River Riders) | Mainly Memorial Day–Labor Day |
River safety
The rivers at Harpers Ferry have strong currents, ledges and debris, and people have drowned near The Point and on the Shenandoah. Wear a life jacket on any river trip, and don't go in on your own when outfitters have stopped tubing. Check the live levels on our current conditions page.

Waterpark morning, town afternoon
Do the waterpark or the river in the morning, then park at the Visitor Center and take the shuttle down to Lower Town for a late lunch and the museums. In summer the last bus back up runs at 7pm, but check the schedule on the day.
