Clovelly is a totally car free village and to get up and down the High Street you have no option but to walk. The High Street is only about 800 metres in length but drops 400 metres in elevation over that length and so even walking down requires a bit of careful footwork on the sometimes slippery pebble cobbling. Walking up however requires a seriously robust cardio-vascular system (not to mention a decent pair of legs - HA but that's another story ;)).
If you don't fancy the walk up though, there is a seasonal Land Rover service which will take you back up the hill via the service road that loops round the village from the Red Lion Hotel back up to the Visitor Centre. The Land Rovers seat (if I remember correctly) 6 people and don't run to any schedule as such, merely departing when they have a fullish load. At the time of writing this costs 2 GBP for the full journey and I GBP to the White Rails. The White Rails being the entry point to the top of the High Street.
The village of Clovelly is situated on the western curve of Bideford Bay here in North Devon and is about a mile or so off the main A39 road (known locally as The Atlantic Highway) with the junction being at Clovelly Cross.
To get to the village by public transport there is a 4 times a day bus service from Barnstaple, run by Stagecoach - the 319 service to Hartland. This is very much a local service winding its way digressingly along The Atlantic Highway through Bideford and then visits the intermediate villages of Abbotsham and the interestingly named Woolfardisworthy (simple called Woolsery!). This is quite a pleasant bus journey provided time is not of essence as the journey from Barnstaple to Clovelly takes about 70 minutes to cover the 20 miles as the bus meanders through the undulating North Devon lushness, catching occasional glimpses of the Atlantic Ocean as it does so.
Because the service is a rural one the fares are subsidised by Devon County Council and hence are quite reasonable. The best ticket option is the North Devon "Dayrider" making the return fare from Barnstaple a mere 3.20 GBP and the ticket is valid for all local Stagecoach services for that day.
If you are a little infirm or easily knackered, walk down and see the main street and the two chapels, then get the landrover back from behind the pub.
I didn't take that option, but I some older people did and it was £2.20 per head.... well worth it.
