Description

Scarba is not served by any public ferries, but access from Craobh Haven or Crinan Harbour is possible by arrangement with local boatmen. The rough summit ridge can be accessed from the harbour at the north end, from where a vehicle track leads up past Kilmory Lodge to a height of about 200 metres. After that, there are no paths or well defined routes, and the terrain becomes rough and boggy. The island rises steeply to a peak (Cruach Scarba) of . A cylindrical triangulation point marks the highest of several summits, which are surrounded by several small lochs.

Corryvreckan

Between Scarba and Jura lies the Gulf of Corryvreckan, known for its whirlpool. Writing in 1549, Dean Monro wrote of "Skarbay" that between it and "Duray":

Ther runnes ane streame, above the power of all sailing and rowing, with infinite dangers, callit Corybrekan. This stream is aught myle lang, quhilk may not be hantit bot be certain tyds. This Skarbay is four myles lange from the west to the eist, and an myle breadth, ane high rough yle, inhabit and manurit, with some woods in it.

Scarba and a few nearby islets ( Lunga and the Garvellachs) are collectively the Scarba, Lunga and the Garvellachs National Scenic Area, one of 40 such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection by restricting certain forms of development.
