Headwater run "activity" holidays- basically walking/ cycling/ canoeing etc. We walked around Gozo (a small place so not too difficult). Headwater supply the maps and suggest routes. There was walk planned for every day we were there, but obviously you can choose to veg out by the pool if you want to!
We went to Gozo about 4 years ago, and really loved Ta Cenc. Would definitely go back when we can palm off dd on the grand parents! The food was lovely, the people lovely, the climate lovely (I think we went in April and i got badly burned because the hazy sun didn't seem hot enough ). The scenery and beaches are great, the little buses are remeniscent of Britain in the 40s and 50s (so I hear!).
There are some funny little museums to see, and the Basilica of Ta Pinu is a must- they have a huge collection of objects left behind as offerings (to Mary, I think), in thanks for miracles worked- strangely, they have at least 1 false leg, but they don't tell you whether the owner was given a new leg after praying there!
We went over to Malta for a day or so (hired a car- beware Maltese drivers- they're lethal!). I remember sitting in a grogeous harbour of an evening eating seafood that had literally been caught a few minutes before...
Hmm, getting all bleary-eyed thinking about it.
In the hotel bar try the local liqueur- can't remember its name, but it's pink, and I think cactuses are one of the ingredients.
Enjoy yourselves!
