We intended to go to Kumburnu beach, but they blocked the roads with wire fences (I hope against the risk of fire) so we chose Taşkapı beach as an alternative. You can bring your own equipment and use the beach for free. The establishment is available (WC and shower are available for a fee), there are alternatives for eating and drinking (a portion of meatballs is 350 TL), there are no sun loungers in the establishment, there are only umbrellas, the sea is clean, I can say that the half-sand, half-stony water is a little cold, but you get used to it. :)
If you're looking to have a unique experience, immerse yourself in the local culture, and enjoy delicious food at affordable prices, then this place is a must-visit!
