Draethen is situated in the county borough of Caerphilly in South Wales. It is bordered by Bedwas to the west, Rhiwderin to the east, Michaelston-y-Fedw to the south east and Lower Machen to the north, with nearby towns and villages including Risca, Rogerstone, Crosskeys and the capital city of Cardiff.

Caerphilly, some 3 miles from Draethen, is well known for its famous cheese and castle, the second largest castle in Europe. Each summer the two combine to host the Big Cheese Festival at Caerphilly Castle which combines historical re-enactments, arts and crafts displays, a funfair and a fireworks display.

Newport also has plenty of attractions to keep visitors to the area amused. The Get Out—Go Country! outdoor team offer activities such as canoeing, kayaking, rafting and archery. The Fourteen Locks attraction, a Visitor Centre beside the canal, gives a computerised virtual journey along the canal and you can even work a lock. Tredegar House, a 17th century Charles II mansion, is another fabulous attraction, with several tours and events held throughout the year, including Halloween and Christmas celebrations.

Last but by no means least is the capital city of Cardiff, it being some 6 miles from Draethen to the very heart of the capital city. The Cardiff Castle grounds are home to The Welsh Regiment Museum and The Queen's Dragoon Guards Museum, whilst the Millennium Stadium lies just a stone's throw away, and is already an iconic building praised for its atmosphere by both football and rugby supporters alike.

There are many walks criss-crossing the hills and valleys and the Rhymny Valley Ridgeway Walk and the Rhymney River Circular Walk meet up at Draethen.
