The state of Delaware has two distinct geological regions with the majority being comprised of the Atlantic Coastal Plains offering little in the way of climbing opportunity. However, the northern tip of Delaware is comprised of the Piedmont Region of the Appalachians. The fall line separating these two geological areas created the Brandywine Valley and is where Delaware climbing has been most developed. Although the piedmont region of Delaware only comprises a small amount of the state, there exists a plethora of unrecorded and undiscovered boulders and climbable rock waiting to be discovered.

            One of the most developed areas in the state is located in Alapocas Run State Park. This state park offers wonderful views of the Brandywine River and offers climbers the opportunity to climb a variety of different top rope routes, as well as some highball-esque bouldering challenges. The climbing wall is maintained by the state and has its bolts and hardware updated when needed, additionally you'll need a (free) climbing permit to climb in this area. Alapocas sees light use and is probably one of the most accessible crags on the east coast.

             For bouldering opportunities, climbers should go to Rockford Park. Consisting of a boulder field running downhill towards the Brandywine River, this park offers incredible shade and incredible views to compliment the sheer volume of bouldering problems available. From dead points and cave problems, to techy slabs and weird off widths, this park has it all.

            Development of both Alapocas and Rockford Park is ongoing, and in these two areas alone there exists ample room for extensive growth. Areas north of the fall line have unfortunately been underdeveloped, if at all. Areas South of the fall line become more and more flat leading to a complete lack of development in the area. In spite of this lack of development north and south of the fall line, there remains plenty of rock to be found and conquered.
