Pego is situated in the centre of the municipality of Abrantes; one of the three parishes that do not front other municipalities within Abrantes. Its neighbours include the parishes of Mouriscas (in the northeast); Concavada (in the east); São Facundo and São Miguel do Rio Torto (to the south), Rossio (to the west) and Alferrarede (in the northwest).

Leaving the main city of Abrantes, towards Portalgre on the EN118, following the left margin of the Tagus, intersects the civil parish of Pego. The road leads along the Ribeira de Coalhos to a small plateau with several small low-rise homes: the first indications of a small settled community.
