You don't need to venture far to find an awesome coast to do snorkeling for beginners.
Sadranan beach, a beautiful beach in Gunungkidul Regency, Yogyakarta, is an ideal place to practice snorkeling.
One thing that you will feel special when you come to Sadranan beach, since you don't get it in other beaches in Gunungkidul, is welcoming instrumental music performed by a group of local musicians playing songs with Indonesian traditional music intruments, "angklung" (a varying number of bamboo tubes), "kolintang" (percussion instrument made from wood), combined with drums and conga.
When i came, they were playing a "campursari" (Indonesian music genre) song entitled "Sido Rondo".
Snorkeling, merely less physical effort if compared to swimming, is a great opportunity to view underwater life from the surface of the water.
Sadranan beach is prominent with its calm sea, so, it's secure to learn snorkeling and you can rent the equipments at IDR 25k.
