Just in case anyone else looks at this question... My husband and I are staying at Hostel Meteora in Trikala! The staff here pointed out several things to see in Trikala. You can see Kastro Castle,there is a zoo on Profiti Ilia Hill, a nice swimming/biking area, and the old city.
We are enjoying ourselves here! over 6 years ago
