“The Largest "Lost Rock"”

"How to find the boulder: Your best route to Rt. 16 in New Hampshire. Two miles south of Conway, you’ll come to the junction with Rt. 113. Turn left (if you’re coming from the north) or right (if you’re coming from the south, take the secondjunction with 113), onto Deer Hill Road (Rt. 113). Drive a ways past a sand-and-gravel company, and you’ll see a brown sign with white lettering on the right pointing to Madison Boulder. Turn right on Boulder Road. Drive past the Transfer Station, all the way to the end of the road, where the pavement ends, and keep on going down a dirt road (don’t try this if your vehicle has low ground clearance). Eventually you’ll come to a small parking area, and there it is: the Boulder. The biggest glacial erratic in New England. One of the largest in the world. Depending on who you believe, it moved somewhere between four and twenty-four miles to get here. It’s roughly rectangular, twenty-three feet high above the ground (and an estimated dozen feet below), eighty-three feet long, and fifty-five feet wide." -http://nielsenhayden.com/makinglight/archives/011265.html

This is an awesome spot! The directions are a bit off but if you just follow the signs for the Madison Boulder. It's pretty amazing.

At fist you think, "how impressive can a big rock be?" Then you see it. Whoa!!! Nice & easy hike for those who might have elderly or otherwise physically challenged folks with them. Very accessible. I'll also note that this site is located is MADISON (thus the name Madison Boulder), NOT Conway. Worth the trip.
