Osea Island Beach Reviews

Jun 05th 2021

We landed on the beach by boat had been then about a hour and a wormen who claimed to be the land own pushing for a fight starting shouting to get off her land and very rudely started throwing all our stuff in the water and standing less then 0.5 of a meter away.

She wanted to call the police for us being on private land.

What did we get wrong?
