Hidden Lakes at Tan Tar A Resort in Osage Beach sits along the shores of the Lake of the Ozarks in central Missouri. Designed by Bruce Devlin and Robert von Hagge and opened in the mid-1980s, the course reflects the bold, strategic style this partnership became known for during that era. The routing makes use of rolling Ozarks terrain with elevation changes and wooded corridors typical of the region, while the lake itself comes into view on several holes, adding both scenic interest and strategic consequence. The design incorporates water hazards beyond the lake shoreline—ponds and creeks appear throughout the layout—and the architects shaped generous, undulating greens that reward precise approach play. Bunkers are positioned to frame landing areas and greenside zones in the Devlin-von Hagge manner, emphasizing visual definition and strategic options. The alternate tees provide different yardages and angles, allowing the course to play to various skill levels while maintaining the design's core challenge. Tan Tar A Resort has long served as a destination property on the Lake of the Ozarks, and Hidden Lakes functions as one of its primary golf offerings. The course caters to resort guests and regional golfers seeking a lakeside round in the Ozarks. The combination of natural topography, water features, and the architects' shaping creates a layout that balances scenic appeal with strategic variety across its eighteen holes.
