The Seaside Course is a golf course in Mario Golf: World Tour. It is the second Castle Club golf course and its tournament must be won in order for the player to compete in the Mountain Course's Tournament. It is located near a beach, similar to Blooper Bay. Due to it being near the beach, sand, palm trees and water are a constant hazard. It, just like Blooper Bay, has bunkers that have different shapes, Fast Fairways, and Island's over the water that the ball can land on. Its background is based on Palms from the previous handheld installment. Collecting all the Star Coins for this course's challenges awards the player with a Wario costume.
