Parliament Hill is the highest point around London.
Some of the best views over London can be seen from the lookout area.
Parliament Hill is also the spiritual home of cross country running in the UK. Some of the best views of 2,000 hairy legs can be seen when the Senior Men's race charges up the hill at the start.
There's also a newly re-surfaced running track at Parliament Hill, used by Highgate Harriers.
There are many activites on offer, including tennis, an open air swimming lido, kids pools, and an adventure playground with swings and slides for kids (check opening times).
The nearest station is Gospel Oak.
