Hello, if you want to avoid crowds please next time come in january or february. Than the park will be empty for you to enjoy its beauties. To come to most popular national park in Croatia in middle of the high season and to complaint about many people inside the park which btw doesnt have to do anything with us is really stupid. You say go at 08:00 to awoid crowds and you left at 08:30 you honestly think 30 mins will make that big difference??:) :)
