Hawaii's ten greatest courses stretch across five islands, from Oahu's oldest championship club to lava-field layouts on the Kona coast, cliffside holes above the Pacific, and upcountry courses cut through old plantation land. Six are private and admit almost no one; four are attached to resorts and open to guests. The pursuit is defined less by any single round than by what it takes to assemble them — inter-island flights, resort stays, and for the private half, an introduction.
