Kuta and Seminyak are the places that most first time travellers to Bali spend their time looking for that idyllic beach vibe. Problem is that they are becoming super commercialised and, to be honest, the beaches can be a little underwhelming compared to others in the region mainly because of the sheer number of fellow tourists and amount of plastic waste. My tip would be to spend your time either to the south in the Uluwatu area for some truly beautiful spots and to visit UluWatu itself and Padang Padang Beach, or just to the north in Cangu, which has a similar beach to Kuta and Seminyak but is worlds apart in vibe
All that being said, Seminyak in particular is worth some day trip visits as it has some truly world class restaurants and beach bars – Potato Head is in my view the best beach bar in the world, with Kudeta not far behind. Sardines, Sarong and Mehra Putih are restaurants I’d also really recommend. And . . . if you must . . . visit Kuta if you’re on a stag do or just generally want some dirty lash
