We took the tourist bus and stopped at the Park Guell stop. This municipal park is situated on Carmel Hill which should offer a clue as to its approach – you have to be reasonably fit or without walking problems to get to its entrance up a long fairly inclined road on a hot day (though I suppose a taxi would drop you off at the gate). This design took advantage of Gaudi’s naturalistic phase and used many organic shapes from nature. It is full of political, religious and mystical symbols and beautiful mosaics.
It is free to enter but some of the attractions, like the monumental area, can be visited if you pay , though I don’t think you need to go there. You could easily suffer from cultural overload during your stay in Barcelona and there are many opportunities to see more of Gaudi’s work elsewhere.
I came across a café/restaurant which did not offer much in the way of snacks but the views from the terrace were worth looking at and spending a few restful minutes there watching the parrots or looking for the hummingbird hawk moth.
The park is well supplied with toilets and most of the free area is accessible to those in a wheelchair.
