Walking Opportunities by steventilly
There are some nice walks on Symi, over the hills to various small bays, and there are loads of little chapels dotted all over the island that you will pass while you do these walks. It's possible to do a walk and get a taxi-boat back (but maybe better to get the boat there and walk back, then you're not under so much time pressure). We did a couple of easy walks to smaller bays during our stay.
