This is journey sprinkled with mystery and magic! Let's have a jolly day!
No Spoilers in advance - You need to be in attendance to enjoy.
Headline planning points for guest subscribers: (not spoilers!)
Wear walking boots and warm clothing.
Bring plenty of drinking water.
Lunch is your choice of using a cafe or bringing a packed lunch. If you bring packed lunch, also bring something to sit on (benches are available, but in December, they'll be wet).
The start point is a tube station, so accessible by public transport.
