In reply to jonny taylor:
I cycled this last year (2023) with my 11 year old son. The track is fine - as above - tarmac, with some potholes - a hybrid bike would be ideal. Only the occasional bus (the cape wrath tourist bus) that passes every hour, and occasional walker. Quiet. Unlikely to see other cyclists. Worth getting in touch with the ferry operator in advance as he doesn;t work every day (phone number on second photo). He is super helpful.
