In reply to loose overhang:
Yes it’s an easy walk from the turn off from the B6049 by the Anglers Rest where the bus stop is (65 bus route Sheffield to Buxton).
Only very limited car parking around this junction though the side of the road immediately before the pub and the pub car park has signs up that their car park is for patrons only. The clearway starts only a few yards beyond the pub.
As mentioned above the other options are the foot of Tideswell Dale past Raven Tor (probably less than the 15 mins walk I quoted) which is free but scarcely surfaced car parking probably with room for about 6 cars.
There is also another proper larger Peak Park car park at the top of Tideswell Dale on the B6049 which is pay and display but free with the annual pass. Lovely walk down Tideswell Dale is free
Similarly with the Millers Station Car Park which is even more extensive but very popular and to access Raven Tor it is nicest and safest to walk back down the Monsal Trail (rather than following the roads) and you turn off to the trail down a steep path/steps to access the foot bridge over the Wye just past Raven Tor.
Note the (free) roadside parking bridge on the B6049 at the Wormhill turn off up to the station car park with the extra wide tarmac pavement has recently been double yellow lined so even if you leave plenty of room for the rare passing pedestrian it is still ticketable.
A bit further up the hill on the B6049 is the pull in for Beginners Wall and Griffs which is best to park back end in to allow space for more cars and a safer exit (room for 5? cars). Not a nice or safe walk down the road though.
Re Peak Parking permit this is good value for regulars at £40pa and you get to use other useful car parks such as the Surprise View Millstone car park and Stanage Plantation one.

If you want to park at the crag at weekends best to get there mega early and as a bonus you generally get to benefit from the best conditions before the sun comes round at lunchtime.
All this said I remain sceptical and think this will fall on deaf ears to the minority who mess things up for the majority. Concerted peer pressure at the crag (I’m sick to death of being a lone voice) and active ticketing of cars on the bend are the things most likely to change everyone’s behaviour sadly.
