There are several anchorages around the islands off the bay, and a not very good one in the bay itself. None are within particularly easy reach of Carsaig. Not that there is a lot to see and do there. In fact it is rather suburban with a scattering of mostly modern houses, and a static caravan site. There really is nothing of great interest, apart from a reasonably atmospheric cemetery in the middle of which is a very uncared for and doorless enclosure for one of the Campbell families. The slightly crumbling jetty is apparently a Telford. If you are energetic enough, and feel the need for some milk or dinner out, you could walk the near mile to Tayvallich on Loch Sween.
On the whole I think it is best just to explore around the islands in the dinghy. If you do go ashore there is lovely typically Argyll countryside to wander around, festooned with primroses and celandine in the spring, with the calls of cuckoos. For example, land at Aoran nam Buth, the bay to the southeast of Eilean Dubh, walk uphill to the east to find a surprisingly large ruined farmstead at Barnashaig, and above that Dùn Bhronaig overlooking a small lochan.
