Las Golondrinas Harbor Boat

• Two routes to choose from: the 40-min harbor loop is great for toddlers; the 90-min glass-bottom coastal boat goes all the way to Port Olímpic
• Running since 1888, departing from the Columbus Monument jetty — the most iconic sea trip in Barcelona
• No advance booking needed for regular departures; just turn up and buy at the ticket booth on the quay

Las Golondrinas has run harbor boat tours from the foot of the Columbus Monument since 1888. The 40-minute harbor tour loops around the port breakwater; the 90-minute coastal tour heads up to Port Olímpic via a glass-bottom boat with underwater views of the seabed. Boats depart from the Moll de les Drassanes jetty, a 4-minute walk from Drassanes metro.
