Sitia Natural or Nature Park (Greek Φυσικό Πάρκο Σητείας)[i] is a UNESCO Global geopark located in the east of the island of Crete, in southern Greece.

The municipality contains the park, except that the naval base at the tip of Cape Sideros and the small islands are excluded.

The premier activities offered by the park to the public, in addition to its two centers, is sponsored group spelunking in the extensive cave systems and group hiking over the peaks and gorges of eastern Crete, for those physically able to perform these arduous activities.

[2] Geopark management was added to the responsibilities of a governmental agency, the Municipal Organization for Socio-Cultural Development of Sitia (DOKAS, abbreviation of the Greek name).

[ii][3] Put together in 2011 under the Kallikratis program[iii] by combination of several smaller agencies, its repertory of managed cultural projects includes others, such as the library and the philharmonic, as well as the geopark.
