Shuna is just over two miles long and about one mile wide at most. Unlike its neighbouring islands, Shuna has little slate and has many trees and woods on the rolling landscape. There are a number of cairns on the island, one said to be the grave of an ancient chieftain.

Lunga ('ship isle' or `long isle') is just over one mile long and about one mile wide at most, and is another of the 'slate' islands. This island is picturesque and hilly, and rises to over 1000 feet. The tidal current between Shuna and Scarba is said to be every bit as treacherous as the whirlpool of Corryvreckan. There are a group of small islands just north of Lunga, including Rolla Meadhonach, Rubha Fiola, Eilean Dubh Mor and Eilean Dubh Beag.

Scarba ('isle of cormorants') lies 0.5 miles north of the northern tip of Jura and about one mile west of Luing. The island is some three miles long and 2.5 miles wide. The west side of Scarba is very hilly and rough, and rises to just under 1500 Feet, while the east side has better land as well as woodland. To the south of the island is the Gulf of Corryvreckan and the famous whirlpool. It is best seen between flood and half-flood, with a westerly or southerly wind - care should be taken if in a boat. There are the remains of an old chapel at Kilmory, but the island is now abandoned.

Garvellachs A group of fertile islands ('rough islands') to the west of Wing and Lunga, held by the MacDougalls, MacDonalds, then the MacLeans. Places of interest include Dun Chonnuill, an ancient fort and 13th-century castle and the monastery on Eileach an Naoimh, possibly first founded by St Brendan in 545, then refounded by St Columba later in the 6th centuryhis mother, Eithne, is believed to be buried here.
