Main road in Menorca is the ME-1. This road crosses from Mahón to Ciutadella. From any place of the island you will find references to get into it. So once there, you will go to Es Mercadal, one of the villages which are in the middle of the island.
Once in Es Mercadal, you will find easy indications to get into Monte Toro. It's a secondary road which goes to the top of the highest mountain of Menorca. The distance to the top is 3 kilometers of slope road. There's an awesome landscape!

Don't look at the hug telephone antennas. The views will talk by itself. Take some pictures as you're not gonna be the only one who does that.
In Monte Toro, you can visit la Virgen del Toro, a very beautiful old church. For sure, the most isolated church in Menorca.
If you are hungry and you are in summer, there is an opened restaurant in the highest point of Menorca. It's called Sa Posada del Toro and it has a good food variety. Lunch with that great landscapes is awesome.
There's also a souvenir shop. ¿why not buying a nice postcard of the wonderful landscapes?
Cala en Vidrier is a very clean and small Beach in Es Grau bay, it has nice sand and it’s a great alternative if Es Grau beach is full of people.
