Only 30 mins drive from Lisbon, great after a flight. Beautiful beach nearby. Camp site very chilled out. Drinks and food very cheap. Free wifi. Close to some great day trips, like Sintra and Lisbon. The only criticism I have is with the marketing by eurocamp. Whilst we loved the site, I was surprised to discover the location was actually 6 miles from cascais. And the beach not quite as close as intimated in the marketing. If we hadn't had a car, there would be the potential to be isolated there. Still, we had a lovely holiday and the site was lovely too.
Pitch a little tight on a corner, but OK. You(Eurocamp) can only work with what the site owners allow you. Site owners and staff excellent. The most courteous we have ever experienced. Your gas b/b/qs are great. We had a chage of couriers, both fantastic.
Parc Guincho is a great base for exploring Lisbon and the surrounding areas. Tha campsite itself has everything you need, we travelled with two children, 3 and 7 years, and found it just right for us. The Eurocamp guide that was posted to us before arrival was particularly useful, as was all the information and toys etc available in the couriers caravan.
