It feels like everyone's going to Lisbon this year. It's probably something to do with its coastal location and warm, sunny climate. It also helps that Lisbon's got castles, monasteries and museums, as well as only being half-an-hour away from golden beaches and superb swimming spots. The only downside? You might have to walk up a few hills to enjoy its cafe culture, food and nightlife.
To get you started, here are 22 things to do in Lisbon, which will help you make the most out of a trip to the city.
The Castelo de S Jorge was rediscovered in the early 20th century during an excavation, which dug up the remains of a castle and royal palace. It's now a national monument and a gateway to nearly a 1000 years of Lisbon history.
The Tower of Belem was built in the early part of the 16th century by Manuel I to protect the city from being attacked by sea. You can still see the medieval keep as well as the more modern military bits. The tower's also much-photographed due to its dramatic location.
The Jerónimos (or Hieronymite) Monastery, along with the Torre de Belem, is now a UNESCO World Heritage site and it is also a National Monument - mainly due to its ambitious architecture. It's incredible that the Igreja e Convento do Carmo (Convent of Our Lady of Mount Carmel) is still standing, as it survived a devastating earthquake in 1755.
The Pharmacy Museum delves deep into 5,000 years in the history of medicine. And granted the Museu Nacional do Azulejo - a museum essentially dedicated to tiles - might not sound the most exciting. But it's actually got some of the most beautiful examples of the famous Azulejo ceramic works in the city.
The 50m-high Padrão dos Descobrimentos (above) was built to mark 500th anniversary of Henry the Navigator's death - one of Portugal's greatest sailors. You can also get a nice view of the mouth of the River Tagus from here too.
The classic engineering of the Elevador de Santa Justa has made this lift a tourist attraction. Save your legs the effort of climbing up to the roof of its gothic tower for a city view.
The flea market in Alfama is the usual mix of tat and artisan crafts. If you loved the 80s - you'll find tons of old toys and games from that era here.
Estufa Fria botanical gardens has some unusual hot and cold plant houses to explore - and it's free on a Sunday. Once you're done with the plants, play count the sculptures (there's loads) and then head to the bar.
The Remodelado trams were built in the 1930s, and we recommend the very pretty Tram 28 route. You can jump off and explore one of the passing neighbourhoods, or use it as a way to get up the steep hills.
The Oceanário de Lisboa's main aquarium holds around five million litres of water and has more than a hundred species living in it. You'll find penguins, otters and sharks, along with plenty of fish. Book online to get cheaper tickets (and you also won't have to queue when you arrive).
The main square in the city is Praça do Comércio, a lively place with restaurants on both sides. Visit the "Old Quarter" and Alfama, you can find a lot of small restaurants and terraces in that area that serve fresh seafood.
Places like Alfama are also the perfect spot to listen to Fado, the traditional Portuguese music - there's usually a live band playing.
They've got a sweet tooth round here - so you'll find Pastel de Nata, or Portuguese custard tarts, everywhere. The best ones are in the Belem area, and you'll see people queuing up to buy them from the place they originated. Or try Bacalhau - the Portugeuse word for cod. You'll see it prepared in different ways throughout Portugal - but smoked, cured or fresh, it's all good stuff. You should also try the fish cakes - Pasteis de Bacalhau.
The Timeout market, Mercado da Ribeira, is a good venue for food during the day, and also a very chilled hangout in evening.
A car park might not sound like the most glamorous of locations - but Park bar is a cool place to have a drink. Aim for the end of the day, and you'll get a 360 degree view of the city as the sun goes down.
The Pavilhao Chines is part pub, part museum, with a good degree of junk in there too. Have a drink and take in the sheer number of objects and art on the walls.
There are Moorish castles, monasteries and old fortresses, not to mention a sprawling forest (it has 500 types of trees) in the Parques se Sintra. Getting there takes around 45 minutes by train from the Restauradores Station or Oriente Station - and the train tickets are only a few euros. It can be expensive to visit all eight sites (costing more than 100€/person in total) so maybe just choose a couple if you're on a budget. To get there you could walk up the mountain or get a bus from Sintra Station and have a glass of wine at the Palace of Pena. Get a TukTuk back down - it can be an hair-raising experience.
Try and bag a birdiePortugal is also home to Europe's "golf coast".
The pretty coastal town of Cascais is around 30 minutes by train or car from Lisbon. This is seafood central. Try the local sole, sea bass or sea bream, and then sleep it off on the sand.
Guincho Beach is close by to Cascais for surfing and swimming, as well as some good coastal walks. If you don't want to get wet - it's good entertainment just watching the surfers and windsurfers from the shore.
