Mare Island Golf Club, whose 1892 founding makes it one of the oldest courses in the country, attracts golfers with breathtaking island scenery. Built near old Marine barracks, the course—which wasn't expanded into an 18-hole layout until 2000—originally sported sand greens, dry fairways, and a cast of unusual inhabitants including a Marine lieutenant's horse, who was drawn to the grounds by career aspirations of becoming a golf cart.

Today, the par-70 course begins with nine traditional, tree-lined holes before opening up on the back nine with a links-style layout designed by renowned Pacific Rim architect Robin Nelson. As golfers swing toward distant greens, views of San Pablo Bay and—on a clear day—the Golden Gate Bridge appear from certain vantages and sand-trap oases.

To perfect a backswing or spell out a marriage proposal with golf balls, players head to the 225-yard driving range with a bucket of balls. Patrons should arrive at least 20 minutes before tee times and can grab a bite in the restaurant or look for one of the 10 ammunition bunkers scattered throughout the course, which serve as a reminder of its connection to the military during World War I and II.
