No real danger for us on our beach visits but the sign clearly shows dangers from falling rocks. Years of errosion caused by winds, tides and sea spray softens the already soft sand stone which surround the small coves - so enjoy all the beach has to offer just keep a look out for any fallen rocks on the beach and if you see any don't sunbath there - keep a close eye on the kids and don't let them add to the damage by climbing on the rocks.
If you hire a car and intend to visit Alte - make sure it is a small hired car complete with air conditioning especially useful in summer's heat. The streets are very narrow and cobbled with thick stone. Once when driving in the narrow streets trying to get out of the village we turned a blind corner only to be faced with a flight of steps running down the whole street. Every one in the small street came out to watch the crazy tourists bump their way down.
There is a restaurant close to the the castle, Cafe Ingles, the location is ideal, indeed one walks through the tables on the entrance the the castle steps. The place is of course busy yet I feel too busy and too expensive, meals only no snacks avialable at lunchtime. There is no other restaurant visible nearby but if you do want something less extravagant what you could do is walk around 10 mins into the town to find many other choices.
I realise getting a parking ticket can happen anywhere in the world!
We got back to our car after a wander around Silves Castle, town & lunch to find a laughing old man sat next to our car pointing out a parking ticket. We all marched off to the local police station, pleading ignorance about not knowing it was a no parking zone (there were cars parked all round us!)
They were not having any of it, then Freya walked in, smilled at the policeman & he let us off!!!
Moral of this story is, always keep a toddler with you!
some of the roads/pavements are made of stone or pebbles and can be quite slippy especially as many of the roads are quite steep.
