Mum, Tracy Hill, sent us this fab photo of Catherine, Amy and Harmony taking a good look around the reserve.
Armed with their back packs they were ready for anything as they started out on their cliff-top adventure.
Tracy said, 'The girls are Wildlife Explorers already, but were over the moon when they got the rucksacks to carry containing the binoculars and books''.
And although two and a half year old Harmony was keen to see the birds, she seems to have spotted something incredibly interesting on the ground.
Ever keen to find new ways to inspire our young visitors to get closer to nature, we've been running children's activities throughout the summer - and we'll be keeping little ones busy during autumn with paper latern making, hedgehog house building and more.
And Tracy's final word... 'A big thank you to RSPB Bempton Cliffs for engaging the children so well. We had a great day'.
