How did you find the pace of the trip?
This Albania family tour is graded as Moderate, which I think is accurate. The trip starts off quite busy, with river wild swimming, exploring the UNESCO-listed town of Gjirokastër and short hikes, but once you reach the coast the itinerary settles down a bit.
Day six of the trip is a free day which you can spend as you wish - either with a visit to a medieval castle, museums and monuments in the Old Town, or simply relax at your own leisure.
