The visitor centre is 5km outside El Paso on the LP-3 highway and offers free general information (be sure to pick up the English Caldera de Taburiente Paths map), detailed maps and guides, an excellent exhibition centre, plus a botanical garden. The centre’s 20-minute film (shown occasionally in English) is worth seeing.
If you want to stay in the park, there is a campsite in the centre near Roque Idafe; you will need a permit, available from the visitor centre. You also need a permit to visit the Mirador de al Cumbrecita. Bus 1 (€1.50 from El Paso, 10 minutes) between Santa Cruz de la Palma and Los Llanos stops by hourly.
