Four championship courses in the Central Sands of Wisconsin — Sand Valley (Coore & Crenshaw, 2017), Mammoth Dunes (David McLay Kidd, 2018), The Lido (Tom Doak, 2023 recreation of C.B. Macdonald's 1917 original), and Sedge Valley (Tom Doak, 2024) — routed through prehistoric sand dunes that give this modern resort an otherworldly links character. All four courses are walking-only. Sand Valley, Mammoth Dunes, and Sedge Valley are resort-accessible, with group tee times requiring substantial advance planning. The Lido is a private destination club with a national membership roster; Sand Valley resort guests can access it only Sunday through Thursday on a limited basis. Sand Valley has been named the USGA's host site for four national championships beginning with the 2026 U.S. Mid-Amateur. Roughly 2.5 hours from Milwaukee and 3.5 hours from Chicago. Pairs naturally with Whistling Straits for a Wisconsin golf circuit.
