Delaware Rockhound Locations

Delaware was one of the first States to enter the union since it was one of the original 13 colonies. While it’s commonly overlooked, rock enthusiasts should not ignore it!

Delaware is the second smallest State in the U.S. and only has a few places to rockhound. The Piedmont region in Hockessin is a decent place to start, but along the beach and local canals are also reasonably plentiful. Delaware is an excellent place to find small Fossils, Quartz, and Sillimanite.

Be polite wherever you explore. Always pack out what you packed in. Meaning if you stop for a snack while rockhounding at any site, clean up after yourself and pack your trash items back out with you.

Always do your research regarding laws and regulations, and don’t forget to ask for permission to access an area and collect specimens.

This article will discuss the top rockhound locations in Delaware and the different types of rocks and minerals you can collect. Don’t forget to make it to the bottom of the page because we list out the best rock and mineral societies in the state.

The best region of Delaware for finding metamorphic rocks is the northwestern part of the State. It’s right along the border of Pennsylvania and is the more mountainous part of the State.

Hockessin and Hoopes Reservoir are two hot spots for finding Sillimanite and other silicon-based crystals.

Hockessin is located right along the eastern border of Pennsylvania. It’s the hillier portion of the State and is primarily rural and suburban.

This is a great spot for finding Garnet and Sillimanite.

Saint Georges and the Chesapeake Canal are excellent spots to find fossils and marine debris, such as sea shells.

Hoopes Reservoir is located just north of Willmington and east of Hockessin. The waterways are a great place for sediment deposits.

This is a great spot for finding Fossils and Sillimanite.

Cape Henlopen is just south of Wildwood, New Jersey. However, the North Atlantic Inlet separates the two States with a small waterway.

It’s one of the best spots to find various Quartz crystals.

The northern part of Delaware borders New Jersey and Pennsylvania. It’s deemed one of the nicest places to live and has several pleasant suburbs.
