Two bridges connect Tui and Valença: Tui International Bridge (known in Portugal as Valença International Bridge), completed in 1878, and a modern one from the 1990s. Both countries are signatories of the Schengen Treaty, so there are normally no formalities in crossing the border-point with Northern Portugal.
Train: Tui station only serves trains from Vigo into Portugal; not into the rest of Spain.
Almost everything in Tui is a 10-minute walk away. Otherwise, you should rent or have a car to move.

The town has two museums, one dedicated to archaeology and sacred art, and the other is the diocesan museum.
The natural park Monte Aloia, 10 minutes away by car.
The fluvial beaches in Guillarei and Caldelas.
The Alameda park and Mariña promenade, which are linked to each other.

Tui is a great town to just have a relaxing stroll. There's plenty of things to see, from museums to the cathedral. It's is a really good centre for seeing Pontevedra Province of Galicia and the Minho province of Portugal.
If you want tapas, O Alboio, facing the main entry of the cathedral, is the best place to go. Albeit a bit pricey (for local standards) the quality of the food is top notch.
If you want a serious, and pricey, meal, the Silabario is a restaurant which had a Michelin star.
If you are visiting the natural park Monte Aloia, there's a restaurant near the summit. The quality of the food is great, and the prices reasonable.
There are plenty of pubs and clubs in the town. The clubs remain open until 06:00 in many cases, so you'll have plenty of time to socialize.
