💬 What Parents Say

• 💡Bring your own food and drinks to save money—multiple reviews mention this option, and with resident admission at just $4 per person, packing a picnic makes it very budget-friendly for families.
• 🕐Arrive right at opening time (noon) or plan for afternoon visits—families with young kids note that the noon start time is challenging, so going later in the day may work better for your schedule.
• 💡Bring proof of Lewisville residency (ID or driver's license with address) to get the discounted $4 resident rate instead of the $8 non-resident fee—this can save significantly for families.
• 💡Take advantage of shaded seating areas scattered throughout the park and arrive early to claim spots—reviewers mention ample seating and lounge chairs, which is essential with young children.
• 💡Note that the toddler shallow pool may have limited hours or closures—call ahead if you have children under 2 (who get free admission) to confirm all kiddie facilities are open during your visit.
