In reply to The Watch of Barrisdale:
> Can recommend a day trip to Gigha - ferry from Tayinloan. Take your bike . It's a lovely wee island with great views west to Islay and Jura.
I agree, I go down there a fair bit ( visit my BIL and sister on their farm)
Last trip I went over the tidal causeway to Davar.
A short walk to the top then dropped down to the beach and walked to the cave painting.
( watch the tide, check with the TI at Campeltown pier)
There are also boat trips from the pier, round Ailsa Craig, and even a rib to Ireland ( Ballycastle)
Bikes free( go and see the Giants causeway and the rope bridge perhaps. £80 return, seasonal)

I would make sure you go to the Mull of Kintyre Lighthouse ( take warm clothes a bite to eat, and perhaps a kite. On the way down/ up , take the short walk to the memorial to the helicopter crash site , and spend a few thoughtful moments.

Go see the seals at Macrahanish , ( and Southend) and if you are a golfer you might want to see one of the best opening holes in the world. ( they have wild goats too on the beach( or in the local gardens) there is a seabird centre too.

On previous trips I went to Gigha, like you I enjoyed cycling, but just hired one on the pier on arrival. I climbed Gigha's highest peak
I then cycled to either ends, watched some Dolphins ( heard a sea otter) and went to the gardens. There is a lovely small beach near the pier, but also a Tombola beach that is worth a visit ( and if you are lucky, the Dolphins ( otters) will be there.
There is a nice drive , cycle round the Carridale road looking towards Arran ( Calmer than the dramatic beaches on the Atlantic )

I had also gone go Islay and Jura ( hitchhiking ) but you can also just hire bikes at Port Ellen , and there is a youth hostel at Port Charlotte , if you want to stay overnight.
My wife and sister go places, no idea what they do. Retail therapy I suspect, crafts I suppose?
If you are lucky there might be a heavy horse ploughing competition on .
Lots more than this , but take a kite and fly it on the largely deserted sandy beaches, watching surfers perhaps, and on other beaches the waves crashing in , pushing pebbles up the beach, and back out again( hypnotic)
