Obidos is a must see and the good news it is motor home friendly and you can even stay overnight if you wish. There is a motor home stopover just outside of the walls by the aqueduct , Rue Does Argos,

In reality you can not miss it as it is just outside of town and you will see the parking by the aqueduct.

It was surprisingly empty and at 6 euros a night a steal. We in fact did not stay the night but were able to park for free.

The aire is visible from the town walls and t o get to the town is simplicity itself, as you just follow the aqueduct  for a few hundred metres.

The town is completely walled and you can have great fun scrambling around the city walls and for a short moment you could easily envisage yourself back in mediaeval times as the buildings are devoid of any satellite dishes, aerials or overhead cables.

You can then descend and wander around the streets and the shops which are unashamedly geared up to the tourist trade, with it seemed, every other shop selling ginjo, a cherry liquor, drunk from mini chocolate cups.

After a very pleasant  morning we decided to head to the coast at Foz do Arelho on Lagos de Obidos and stayed at the Orbitur site, which at 21 euros was our most expensive site. In hindsight we would have stayed at the aire on the lagoon, that we cycled past at 3 euros and at this time of the year it was not too busy, with space between the vans  and the prospect of a lake view. This certainly would not be the  case in the high season.

Still we had an excellent pitch on the Orbitur site with plenty of room and lashings of hot water, wi fi  and  electricity though I could not find a motor home service point.

You can cycle for a reasonable distance along the lagoon, off road though the other roads are not busy.

The lagoon and the coastal beaches are superb and at this time of the year (May) not very busy,
