• Free to ride, from the signposted stop in the middle of the park; school and group trips leave from a separate stop
• Weekends and holidays only from November to March, with weekday afternoon trips the rest of the year
• Strollers and wheelchairs fit on board, but pets, bikes, scooters and bulky items stay off

A small electric train, built to look like an old steam engine, pulls open carriages on a 30-minute loop around Parque Juan Carlos I. The route runs past the ría, the lake, the Estufa Fría greenhouse and the park's long promenades, and an optional recorded commentary tells the park's story along the way. Each train seats 50 and has a space for a wheelchair.
