Morvern provides you with loads of opportunity to enjoy the great outdoors. From hiking in the hills, swimming in the loch, cycle across the peninsular, kayaking, wildlife watching.
For inspiration check out these walks.
You can swim in the sea loch, in the sound and in loch Ariana. You might want to bring a wetsuit, really depend on your disposition.
Why not bring your bikes and explore the peninsular, or rent electric bikes locally.
If you bring your own kayak, then the loch is great for kayaking and so is loch Ariana, for the more adventourous you can explore the sound of Mull.
There is opportunity to both fish the river and the lochs, permits from Ardtornish estate.
