Donousa attracts hikers and beachgoers, while the Donoussa Trail Run is becoming popular with runners. There are also a couple of worthwhile caves, accessible from Stavros by boat.
Donousa has five numbered and well-marked hiking trails, four of which are old trails that connect the villages. They are:
- #1: Stavros to Kalotaritissa (4.4km, 1¼ hours) The longest and toughest of the trails, with steep sections and terrific views.
- #2: Kedros to Messaria (1.1km, 30 minutes) Connecting the most popular beach with the hamlet.
- #3: Mersini to Livadi (0.9km, 30 minutes) Steep trail down to one of the lovelier beaches.
- #4: Kedros to Kato Mylos/Vathy Limenari (2km, 45 minutes) Coast-hugging trail connecting Kedros Beach to the Limenari Beach via a ruined windmill.
- #5: Kampos to Limni/Aspros Kavos (2.1km, 40 minutes) Trail starts near Stavros and leads to the tip of a remote cape.
It is a rocky and dry island covered in scrubland and with very little shade, so be prepared with decent shoes, plenty of liquids and sunscreen. The main beaches of Kedros, Limenari, Livadi and Kalotaritissa can all be reached on foot on these marked tracks.
