The amphitheater is an excellent ice climbing spot located in Grafton Notch. It has a relatively short approach, is rarely crowded, and is easily top roped. The and the approach also offer some incredible views out into the notch. Because of its location, it tends to hold ice even during warm winters.
Drive past the parking for the trailhead up Old Speck for about half a mile. On your left you’ll see a pullout with a sign marked cable road. Park here and follow the cable road straight for about 100 feet, then turn off left into a marshy area. There are blazes leading to the cliff but it can be tricky to find if the trail isn’t packed down (I’ve added a second point on the map above with the approx. location of the cliff). Head uphill steadily until you reach a cliff. If you hit a clearing ~ half way you should be on the right track. Once at the cliff, walk around climbers right and set up some top ropes or lead something to the top.
