Calla en Porter is another one road in-one road out resort area, depending on an infrequent bus service to get anywhere. There is a very pretty bay with a small beach which can be reached if you're up for a steep walk. There are lots of small supermarkets, cheaper than some of the resorts we visited but more expensive than in less isolated areas. There are also plenty of restaurants (which we thought were a bit expensive compared to the rest of the island) and cafe's (which were more reasonably priced) - bring a hearty appetite, because everywhere serves obscene amounts of food on massive plates.
RANT WARNING One restaurant that caught our attention was a steak or rib place, with a sign informing everyone that they "pay staff peanuts" and if you get good service you should leave a tip. Is this Europe or America? This is so inappropriate for an area which caters to English tourists (for the non-English out there, quite simply, we DON'T tip - it's degrading to both parties and not the done thing). I know we're not alone in saying we wouldn't give our business to anyone who boasts that they don't pay their staff very much. Needless to say, they weren't doing much trade. Rant over.
Overall, Siesta Mar did us for a couple of days, but to be honest I don't think we'd like to stay there for any longer.
