Poros Reviews -General

For an easy few hours away from the island, take either the car ferry or one of the many small boats across to the mainland and the village of Galatas, here you will find another real working town, where there are many local shops, nice cafes and tavernas.
If you want to venture further, again on the mainland there is Lemonadasos (lemon grove), to get there it is best to get a taxi from Galatas, to the Taverna at the top of the groves, have the best tasting glasses of lemon in one of the most traditional tavernas I have been in, and then make your way through the groves (60 mins) to the main road, either pick up a taxi to the town, go to the Poros marina and get a boat back to the island or walk back into the town (45 mins)and get a boat from there.
For a trip around the island which includes lunch, try the 2 brothers boattrip. A good day out with 2 lots of deep water swimming.
The Classical tour trip is worth doing, althought it is a little expensive.
