Locals please help. Closest public transport to the viewpoint at Parliament Hill Fields?

I’m going round in circles on apps trying to decide!
Thank you

What do you mean by public transport? Bus? Taxi? Or just train/tube? Where are you coming from?
Also, if distance is an issue, are hills an issue? Would a slightly longer route with a more gentle climb suit better?
I will now leave it to the locals to actually answer your question.

Gospel Oak overground.

Hampstead heath overground. Exit right and walk up parliament hill (road) there’s an entrance to the heath that’s at the bottom of parliament hill. Gospel Oak station is a further walk.

Thank you for the quick replies and help. Hampstead heath it is then 👍
