The bike-hire scheme Sitycleta has stations dotted around the city.
Yellow buses (guaguas municipales; www.guaguas.com) serve the metropolitan area. Pick up a route map from tourist offices, kiosks or the bus station. Individual journeys are all €1.40 but if you plan to take the bus more than a few times, it's worth investing in a 10-trip bono de guagua (€8.50), on sale at bus stations and newsagents. One bono de guagua can be shared between a number of users.
Yellow buses 1, 12, 13 and 17 all run from Triana northwards as far as the port and the northern end of Playa de las Canteras, calling by the bus station and Parque Santa Catalina.
The hop-on, hop-off City Sightseeing Bus is a good way of getting an initial overview of the city. The main departure point is Parque Santa Catalina, but you can jump on at any of the 10 stops between there and Vegueta.
Driving in Las Palmas is a pain, with the normal big-city rush-hour traffic jams and a baffling one-way-street system. Most of the centre operates meter parking (coins only), but finding a space is challenging. Otherwise, there are several underground car parks, where you pay around €2 per hour. The most central are at Parque Santa Catalina, Plaza España and at Parque San Telmo, opposite the main bus station.
If you need a taxi, you can call, flag one down or head for one of the plentiful taxi stands across the city.
