Dune di Tirrenia, Nature reserve on the Mediterranean coast in Tirrenia, Italy.

Dune di Tirrenia is a nature reserve on the Mediterranean coast spanning 24 hectares with coastal dunes rising several meters high. Mediterranean vegetation including maritime pines and shrubs grows across these dunes close to the Tyrrhenian Sea.

The reserve was founded in 1997 by WWF Tuscany through a partnership with Pisa Municipality, Migliarino Natural Park, and Pisa Province. This collaboration made it possible to protect this valuable coastal area.

Educational panels throughout the reserve explain the local plants, animals, and how the coastal dune ecosystem works for visitors. They help people understand why this environment matters and what lives here.

Pedestrian access to the WWF-protected dunes is free, provided visitors follow the information on the wooden barriers and signboards. A path for people with reduced mobility runs through the oasis and was extended in 2011. Several dirt tracks cross the 24-hectare area toward the beach, which is partly free and partly occupied by bathing establishments.

Periploca graeca, a rare climbing plant resembling tropical lianas, has in the Migliarino, San Rossore, Massaciuccoli park its most important Italian station. At Tirrenia it grows in small hollows between the dunes, together with rushes and reeds. The reserve also shelters Solidago litoralis, a goldenrod found only on the northern Tuscan coast.
