Devens DGC - The Hill
A really fun, challenging course. It's tough to find the first tee, so I'd advise printing the map from the Devens website. Crazy elevation changes and giant boulders make this a drastically different experience from the average course. Wear good shoes and don't expect to par it the first time around.
Bring your short and long game to the hill! A great mix of long and short holes, thickly wooded in spots. Hiking shoes are a good idea! I almost killed myself in my NB
