It is in the middle of nothing really. Visited Watukarung on July 2023, and we fly via Jogjakarta and took 3.5hours drive by car, we have someone picked us up at the airport. There are few options of guesthouses to stay, make sure they have hotshower, aircon and comfy bed if you're those kind of people.
Restaurants and cafes are limited, however there is one pizza place that only opens for dinner and if you are okay with simple Indonesian dishes, there are view warungs to go.
Holidays and weekends will be full of locals that spend time at the beach and relaxing.
