looking at going to aghia paraske, want a resort close to skiathos town tho. dont want to be too far away, thank you in advance
Skiathos is about 12 kilometres (7 miles) long and 6 kilometres (4 miles) wide on average. You are right in the centre of the island, half way to anywhere. So say three to three and a half miles.
Excellent choice, if not to your exact specification, for distance from town ...
Nearest to town is Megali Amos (Walking distance) Or Achladies (Water taxi)
Try this map to help familiarise yourself with the island.
Jan, Aghia Paraskevi has so many fans -but, as has been said before, Skiathos Town is the only actual Resort on the Island. Other places like Troulos, Kolios, are areas that have nice tavernas, small food shops, perhaps a bakery, but are not massive places. That said, some of the Tour Operators' guide books would tell you otherwise. However, the countryside is very beautiful and yes, many visitors prefer to be away from the town.
SL1, same map, different links :)
Jan, another consideration is the time of year you plan to visit. If you hire a car, no worries.
In May, early June the bus service is perfect. In July & August (never been in August but can imagine!) Getting on a bus into town early evening can be a trial. Doable but very very busy.
If you want "close to town" as SL1 suggests, look at Megali Amos.
