Must-reads for the prospective Almancil visitor begin online with articles from the Times Newspapers of the United Kingdom, two of which are linked to from here.

Frommer’s online subsection
dedicated to this Algarve resort hub is worth a perusal, and its “planning a trip” section is fairly strong, but it would be most recommended to check the city and province’s official tourist sites first.

Although  there is not much in the way of books pertaining exclusively to Almancil, texts such as The Rough Guide to The Algarve by Matthew Hancock give more than adequate amounts of information regarding the city.  Try Traveller’s Algarve and Southern Portugal, by Susie Boulton, Martyn Symington, Joe Staines, and Sarah Le Tellier, a book with good maps and descriptions all the sightseeing to be done within Almancil and a short radius outside.

For guides to greater Portugal, Eyewitness Travel Guides’ Portugal by Tomas Tranaeus is a safe bet, as is Fodor’s See It Portugal.
