Pukaha Mt Bruce's Junior Ranger programme has proved a hit with kids this summer.
Pukaha general manager Helen Tickner said the programme had been a popular Christmas present, with kids enrolled eager to return for another visit.
"What is quite nice is we've had kids on the programme ask to come back with their families."
The summer holiday sessions are fully booked for the rest of the holidays, but spots were available during the next break, Mrs Tickner said.
Foster Hammond, 11, of Carterton, had just finished his day as a ranger and said it was a special birthday treat.
