Recommendations for Free or Low-Cost Beaches in Rhodes?

Hi r/Rhodes! I'm planning a trip to Rhodes and looking for free or low-cost beaches to visit.

Any recommendations for beaches with no or minimal entry fees? Also, any tips on sunbed/umbrella rental costs or other things to know?

+ Grok tells me "Elli beach" and "rondo beach" is actually free, but if you want a sunbed/umbrella than it costs 40+ euros. Is it really true?

I'll be going to rhodes next week with my girlfriend, any other recommendation would be great!

Thanks in advance!
