The Thrill Ride O' Love was Waterland's version of a Tunnel of Love. The ride had forty-five-degree plunges and pictures of Romeo and Juliet and other Valentine's Day-related art. There was a golden Gate of Love at the end where it led outside the tunnel to an exit pool.
The empty pool was at least fifty meters (fifty-five yards) across and shaped like a bowl, around the rim there were bronze statues of Cupid standing guard with their wings spread and bows ready to fire. There were also multiple mirrors in the room as Percy Jackson comments that Ares and Aphrodite would be able to see themselves from any angle. There was a tunnel leading to the pool, with a sign above it reading "THRILL RIDE O' LOVE: THIS IS NOT YOUR PARENTS' TUNNEL OF LOVE!"
Percy, Annabeth Chase, and Grover Underwood had to enter the ride in Waterland to retrieve Ares' shield. They, however, did not know that there was a trap set by Hephaestus. Percy and Annabeth had to go through the tunnel in order to escape numerous metal spiders. As a daughter of Athena, Annabeth was deathly terrified of spiders. The two managed to escape when Percy channeled the water from the pipes into the room. The water pushed them toward a closed gate at the exit forcing them to jump over the gate at the last minute, but Grover caught them, with the help of Luke Castellan's winged shoes.
