Unless this is inside the PierCo building somewhere, it is likely pinned in a wrong location.

No playground here during winter season, is it perhaps a summer season feature on the Rising Star Hotel grounds?

There is no sign of this establishment here. The building and terrace area are in use by NAVA.

No sign of Maria Leather Shop at this location. The tagged premises are occupied by Blue Surf Property.

Path between Sirena Beach and Paralimni Marina impassable due to Marina construction works.

The footpath splits three ways here. Main one leads downhill as marked. The other two I have not checked but run parallel to the hill slope.

No sign of "Tropical" Restaurant here. Perhaps it is unmarked and actually located inside the Blue Ivy Hotel.

No sign of Angel Silver Jewellery here, may have been closed down as has relocated elsewhere.

Passed by on 21-08-2023 and could not find this trail.

There is no playground here in winter, maybe it is a summer-only feature?
