This is an excellent location, which loads of walks from the doorstep, and Ainsa is a joy. You will be allocated a site, which tends to be in a busy area, but I found that you can move to a quieter site with better views. The  Spanish tend to congregate together and in family groups, so can be noisy, but out of season you can easily have a quieter pitch. There is an area which has greener grass and higher hedges which is nice with good views..... Other areas have hedges still at the baby stage and look less appealing. Having said this there is direct access to the river side from these which is better with a dog which I have.....and I did not see any dog mess on the site, but plenty just outside....the concept of bagging it does not seem to exist. Great swimming pool and bar area.
