The scripture doesn't make clear whether Paul actually went ashore on the island of Samothrace, but the ship was apparently only in the area one day before heading to Neapolis.(Acts 16:11). It is said that, even today, the present-day island of Samothraki offers places to safely anchor a large ship, while not having a particularly good harbor for disembarking.
Paul visited Corinth during his second missionary journey, where he stayed for over a year and a half. He visited Athens during his second missionary journey as well, after leaving Berea and before arriving in Corinth.
1 and 2 Thessalonians were written during Paul's Second Missionary Journey.
On Barnabas's second missionary journey, he took John Mark and sailed to Cyprus, which was Barnabas's home island. They aimed to revisit the churches they had established during their previous missionary work. However, their journey later diverged as Paul chose Silas for his own missionary efforts, leading to separate paths for Barnabas and Paul.

Paul's Second Missionary Journey began with Syria, Cilicia, Derby, and Lystra. He then passed through Phrygia and Galatia to Troas. Paul then sailed to Samothrace, Neapolis, and on to Philippi. Thessalonica was the next major stop and after a lengthy stay, Paul moved to Berea, Athens and Corinth before returning to Jerusalem via Ephesus.
49 AD
Paul's second missionary journey was to Greece A.D. 50-53.
approximately 1,400 miles
During Paul's second missionary journey he spent 1 year and 6 months at Corinth.
Paul met Timothy, who was to become an important part in establishing the church and assisting Paul in his ministry. He also met Lydia, the jailer at Philippi, the Bereans, Dionysius and Damaris in Athens, Priscilla and Aquila at Corinth, Crispus, and Apollos to name but a few.
Paul received the "Macedonian call" while on his second missionary journey. His first trip to Europe was in response to this call. You can read about when Paul started his second missionary journey in Acts 15:36-41, and when Paul received the "Macedonian call" in Acts 16:6-11, and read about the first convert in Europe in Acts 16:14-15.
Silas (Acts 15:40) Timothy was added at Lystra Acts 16:1-3. Luke is the recognized author of Acts and has references later in chapter 16 that use the pronoun "we" so he was apparently with them on this trip.
