PEOPLE will have to be up with the lark on Sunday, May 8, to catch Richard Aspinall, head ranger at Oakwell Hall Country Park, Birstall.
He will be ready at 4am to lead a walk to listen to one of nature's best sounds - the dawn chorus.
Richard said: "It's an early start and earlier than we have ever done it before but, I assure you, it is definitely worth it.
"There is no more inspiring an experience than the dawn chorus."
To help bolster the early risers, walkers will have the option of a full English breakfast in the Oak Tree Café after the walk.
The walk is free but, as numbers are limited, places - and breakfasts - have to be booked in advance. The £6 breakfasts must also be paid for in advance. Phone 01924 326240.
