What to visit in June?

Hi, we (my wife & I and her family) are visiting Antalya in June. We’ll be staying near Side and hiring cars.

Any recommendations for places to visit? We’re keen on nature / waterfalls / lakes etc (as well as sandy beaches with clear sea!).

We visited Fethiye last year and found some stunning gorges / waterfalls so would love to find similar around Antalya / Alanya.

Thank you!
