Birthday Party Rental Request Form

You bring the cake, drinks, and paper goods, and we’ll provide the nature-filled fun. To ensure the best experience for the children, we ask that there is enough adult supervision on the trail, and that most adults remain at the back of the trail or in the party room so the kids can fully enjoy their program.

Planning for a larger group or hoping to include more adults? We recommend booking a facility rental instead, click HERE for more details.

Before booking, please click HERE to review the information page to confirm that our Nature Birthday Party Package is the right fit for your celebration.

Let us help you create a day filled with joy, laughter, and memories that will last a lifetime. We are now booking through June 14, 2026. We look forward to assisting you with booking our venues.
