Connecting with the Cataño ferry

The western end of Route 4 is the ATM Ferry Terminal, where the Cataño ferry departs to cross the bay to Old San Juan in about 12 minutes. It is a handy combination for reaching the old town by sea.

⚠️ The ferry is NOT free. The current free-travel period only covers AMA buses and the Urban Train. The ferry is operated by HMS Ferries under fares set by the Government of Puerto Rico. Since 1 January 2026, by order of PRITA, the general fare has risen to $2.00 per trip. Children aged 0-2 travel free, and reduced fares exist for seniors and passengers with disabilities. Check the exact age bands and prices at puertoricoferry.com before travelling: the official site does not always reflect fare updates immediately.

Cataño–San Juan ferry times: Monday to Friday, 5:30 a.m. to 9:30 p.m. from Cataño; Saturdays and Sundays, 7:30 a.m. to 10:30 p.m. Unlike the bus, the ferry does run on Sundays.
