To reach Castle Craig you drive into Hubbard Park, neat and green and meticulously landscaped, centered around a large lake with multiple fountains. It's practically Midwestern. (This is totally a compliment.) And then you keep driving. You might think you're immediately going to drive up, but what you do is drive along...and along...and over the river and through the woods and over some more woods and some more woods until you wonder if maybe you're lost. Which would be embarrassing. The roads within the park technically have names, in a theoretical, Google Maps sense, but there are no signs. In fact, except for a sign at the gate near the park's swimming pool, nothing on the way to the tower is marked. You just have to guess, and go slowly on the narrow two-way road - especially where it crosses the water on a low bridge - and remember to turn left at the fork. And then, eventually, you'll be in a parking lot, surprised to find that you've ascended 976 feet. The parking lot is right below the tower; Castle Craig, like the Fox Hill Tower in Vernon and unlike Haystack Mountain in Norfolk, is a lazy-person attraction. (Though you can hike up here too, if your knees are better than mine.)
Metacomet, by the way, is sometimes called Metacom and is the same person as King Philip, who you might know from his eponymous war.
