Thirteen holes. Not nine, not eighteen. Thirteen. Tamarack operates on its own terms, a semi-private layout in Naperville that refuses conventional math. The oddball routing works for walkers who want more than a quick nine but less than a full commitment. At 70 walkability, you will encounter some terrain. Nothing brutal, but bring comfortable shoes and expect mild elevation shifts between greens and tees. The shorter format means you can loop it twice for a full day or play it once and still make dinner. Naperville has plenty of golf options. This one stands apart by not trying to be something it is not.
