Don’t bother with the Magpie, it’s perfectly fine but not as special as its reputation suggests
This. It's just the same as all other Yorkshire fish and chips, it just has better PR. I've given up chasing after 'these fish and chips are best' after making a point of visiting them all over the place, because they've either been nothing special by Yorkshire standards, or in many cases not as good as our very average local suburban chip shop.
If you want to visit the abbey area, which is nice for a wander around and cliff top walk, there's parking up there, no need to walk up and down the steps unless you want to.
If you go to Sandsend, which is lovely, you can walk in the Mulgrave woods up to the castle but only on Wednesdays or at the weekend.

I like the Fish Cottage takeaway in Sandsend and I think they did non fish options. There's also lovely sandwich shop but they are insanely popular, have queues and often sell out, so if there's something specific that you want, go early. I've been twice now and once left with nothing and the second time, my third choice of sandwich after a 40 minute wait (which was fine because I went for a walk then had a beer looking at the sea).
