Yes, the vast majority of beaches in Split, Croatia, are completely free to the public, as Croatian law generally dictates that the coastline is a "public good" and cannot be entirely privatized. Popular spots like Bacvice Beach, known for its shallow sandy waters and the local game of picigin, are entirely open access. You can simply walk onto the shore, lay down your towel, and swim without paying an entrance fee. Even the more "manicured" pebble beaches like Kasjuni or Bene located within the Marjan Forest Park do not charge for entry. However, while the access is free, many of these beaches feature private "Beach Clubs" or concessionaires that rent out sunbeds and umbrellas. These rentals can be quite expensive during the peak summer months, often ranging from 20 to 50 Euros per set. If you choose to use these facilities, you are paying for the comfort and service, but you always have the legal right to sit on the rocks or pebbles nearby with your own gear for free. The only exceptions are very rare cases involving specific luxury hotel segments, but even then, a public path to the sea is usually maintained.
