Need reccs for exploring nature’s beauty in LKO

Hello everyone, I am new to Lucknow, but some of my friends are visiting me next week. They only have the morning slot from 9 AM to 12 PM to explore our city. Both of them are amateur photographers. I wanted to take them to some places which are rich in Natural beauty. To show them the sunrise, lakes, rivers, greenery. Please let me know if you have some suggestions, thank you in advance .
