The three boys, aged around 15, had left their homes on July 21 and went on a trip to Rajasthan for "fun", senior inspector Prakash Birajdar of Tulinj police station told PTI.
Parents of the trio, two of them students of class VIII, filed a missing complaint with the local police after they failed to trace them in the neighbourhood.

The team then with help of local police in Rajasthan, found them at Swarupganj railway station in Sirohi district and brought them to Vasai.
The boys were reunited with their parents last evening, Birajdar said.
