This is the premier wall at Bald Bluff. 100+ feet tall and 300 feet long this wall is a stunner. Vertical to gently overhung, this wall has fantastic climbing from 5.10 to 5.12. The Dike Wall has some of the most interesting features to climb in Western Maine. Large and small chunks of basalt were left sticking out of the wall as the dike eroded leaving some truly amazing square-cut holds to grab. "Welcome to Greenwood City" and "Spikes & Twine" are the best ways to climb these features. 

Parts of the base of the Dike Wall run steeply uphill and are not very accessible. Thus the routes are accessed at three different points (Lower Dike, Middle Dike, Upper Dike). Although you can scramble up the actual dike, it is not recommended. Loose blocks abound and can create a serious hazard for both you and other climbers. 

Lower Dike - From the end of the approach trail, walk underneath the overhangs of the Bastard Wall leftwards to the very bottom of the dike. This is the belay spot for both "Spikes & Twine" and "Welcome to Greenwood City". 

Middle Dike - From the end of the approach trail, follow the trail steeply uphill past several interesting caves to where the gully peters out. From here take a left and follow the obvious footpath to the base of the cliff.

Upper Dike - From the end of the approach trail, follow the trail steeply uphill past several interesting caves to where the gully peters out. From there follow a trail uphill and to the right of a short outcrop then back left across the top of the outcrop to the cliff.
