In the 1990s archaeological excavations were carried out in Ballygally and remains of a number of Neolithic houses on low ground about 500m from the shore of Ballygally Bay were discovered.

 Places of interest
Notable features include a sandy beach and the distinct headland of Ballgally Head.
It is also home to Ballygally Castle, reputed to be the oldest occupied building in Ireland and with a reputation for being haunted. It sits in the middle of the village and is currently used as a 4 star hotel. It was built around 1625 for James Shaw of Greenock and is one of Ireland’s best-preserved Scottish baronial style plantation houses. Ballygally, despite the shop being demolished in 2008 to build flats, now has a brand new two-storey building, funded by the Big Lottery, Larne Borough Council and NER. The building consists of a large Spar shop at ground level and a Community Hall on the first floor. This will be the venue for many social activities in the very near future. Restaurants, pubs and Cairndhu Golf Course are nearby. Ballygally beach is a popular destination during the Summer months. Situated 1–2 miles away is the Carnfunnock Country Park, which offers a cafe, trailer park, a children's park, go-cart racing, clay pigeon shooting, mini-train rides, bungee runs, mini-golf and nature walks.

Wedges of agglomerate have been found around Ballygally Head, showing that there were several stages of eruption, allowing tuff to form before the vent was blown out and once more filled with magma. There are tall columns in places around Ballygally Head, similar to the basalt columns found at the Giant's Causeway, but these are dolerite, a rock similar to basalt but which cooled more slowly, held inside the volcano vent, and so had time to grow larger crystals.
Scawt Hill, another volcanic plug 5 km west north west of Ballygally, is an internationally important site for geology due to the rare minerals found there. It is a protected Area of Special Scientific Interest.
