Spring Fling & Glow Egg Count

It’s a new twist on an Easter Egg Hunt! April 4 & 5, 2026

Have you ever seen glowing Easter eggs? We’ve discovered that the Easter Bunny hides lots of different colored glowing eggs inside Rushmore Cave. It happens each year over Easter weekend. So, make plans to come on out, take a cave tour and count all the glowing eggs you can find for a chance to win a GRAND PRIZE! Plus, the first 250 children are guaranteed a goodie bag! (Note: You do not collect the eggs, you count the number of different colored glowing eggs you see. This way, everyone has a chance to find and count them all.)

In addition to finding the glowing eggs inside Rushmore Cave, you can ride the Rushmore Mountain Coaster, 2-seated Zipline ride, Gunslinger 7D interactive/virtual reality ride too! PLUS, face painting, games, prizes and photos with the Easter Bunny are all included with the purchase of a cave tour ticket, wristband, or season pass. (Tickets for just the Glow Egg Count alone are also available.)

While the egg glow event is geared for ages 12 and younger it will be fun for everyone!

It happens each year on the Saturday and Sunday of Easter weekend

Weather Notes: We will proceed with the event unless SD DOT issues local road closures.

Once in Ticket Page select either April 4 or 5 to view Spring Fling tickets.

Tickets available for Egg Glow Count event OR are included with the purchase of a wristband on those dates.
