The municipality is of great transportation importance because of the major railway and highway networks connecting Rijeka with Ljubljana and Trieste to the west, Zagreb and Split to the east and Pula to the south through the Učka tunnel. Sixty five percent of the annual Croatian border traffic takes place through four international border crossings - Pasjak (with Starod in Ilirska Bistrica municipality on the Slovenian side), Rupa (with Jelšane), Mune (with Starod), and Lipa (with Novokračine) - within the Matulji municipality. Šapjane, a main railway crossing into Slovenia with Ilirska Bistrica) on the Slovenian side, is also in the municipality.

The Opatija - Matulji railway station, the principal railway station for Opatija and surrounding municipalities, was constructed and opened in 1873.

The A7 motorway starts in the northern part of the municipality, on the border crossing with Slovenia and connects with the A8 expressway at the south, next to Rijeka and Opatija.

The region is well known locally for its Istro-Romanian folklore, namely Zvončari during the carnival festivities.
