Hi
Mijas is a lovely village to wonder round and explore. If you walk to the other side of the square where the coach turns round, there is a lovely bar/restaurant with fantastic views of the sea, just the place to people watch with a glass of wine, they do great sandwiches too!!. The village is perfectly safe to wonder round at night, a few of us went out on a couple of evenings after dinner for drinks and some went to a restaurant for paella. The hotel has a great pool area ideal for sunbathing. Don't miss the gardens just up and to the left of the village, the views are breathtaking. There is also a bullring which is worth a visit but the one in Ronda is much larger and I think the oldest in Europe.
On my trip there were 44 other people and although you may not get to speak to all of them [or remember their names] I am sure you will easily make friends with quite a few.
Hope you have a fantastic time and try and do all the trips it will be worth it.
Best Wishes
Bev
