Visitor Tips & Planning Your Visit

Getting the most from your trip to Rock’N River requires a bit of planning. Here are tips based on visitor reports:

1. Arrive Early

Since capacity is limited, arriving early helps you secure parking, seating, and access to slides before crowds build.

2. Use Twilight Admission

If you can’t stay all day, the twilight hours (last 2 hours) offer a reduced rate—perfect for evening fun at a lower cost

3. Bring a Cooler & Food (Within Limits)

Small coolers (under 48 quarts) are allowed—but expect bags to be searched. Glass, alcohol, and large items are prohibited. 
Food trucks and a swim-up concession (Watering Hole) are available onsite for snacks, drinks, and light meals.

4. Be Mindful of Height Restrictions

Before heading close to slides, get kids measured and tested (if eligible) so you know which attractions are open to them. This prevents disappointment mid-visit.

5. Plan for Shade & Sun

Though there is some shade and cabana rentals, space is limited. Bring hats, sunscreen, umbrellas, and towels.
Pick lawn spots early to claim comfortable places for breaks.

6. Lockers & Belongings

Lockers are available for rent (small, medium, large) via the General Store (for a fee). 
The General Store also sells swim diapers, goggles, etc.

8. Bring Approved Life Jackets

If needed, bring a US Coast Guard–approved life jacket—they are allowed when outside floaties are not.
