Fares start at about €3 on TITSA 343 from TFS T1
TITSA bus 343 runs directly from Tenerife Sur Airport (T1) to Santa Cruz and Puerto de la Cruz, with fares starting around €3–€15 depending on distance. The line connects both Tenerife Sur (TFS) and Tenerife Norte (TFN), so you can transfer airports without touching taxis. You board at the main bus stop right outside the arrivals area of T1, next to the green-and-white TITSA signs.
The 343 usually runs multiple times per day, with a rough span from early morning into the evening, but exact times shift by season and weekday. Typical ride time from TFS to Santa Cruz sits around 50–60 minutes, and about 70–80 minutes to Puerto de la Cruz, traffic depending. Buy tickets directly from the driver on board, or load a Ten+ card beforehand at airport machines if they are working that day.
This is a normal public bus, not an airport express, so you share the ride with locals traveling between Santa Cruz, the north, and the south of the island. Luggage goes in the underfloor hold; the driver opens the side doors before you tap or pay. A one-way between TFS and TFN on 343 usually lands around €10–€12, much cheaper than a taxi quoting around €90–€100 for the same cross-island run.
The stop at Tenerife Sur Airport sits on the public side, outside security, roughly a 2–4 minute walk from arrivals in T1 depending on where your luggage belt is. Signs read "Bus / Guaguas" with the 343 number listed on the timetable at the pole. The same stop also serves other TITSA lines such as 111 or 711, so double-check the front display on the bus for "343" before you load bags.
Seats on 343 are standard intercity style with basic air conditioning and no guaranteed Wi‑Fi, and there are no assigned seats or seat reservations. Drivers usually accept contactless cards and cash euros, but small notes like €5 or €10 make the process faster than handing over a €50. Keep your ticket until you get off at Santa Cruz Intercambiador, Puerto de la Cruz bus station, or TFN, as inspectors sometimes board on longer runs.
Practical tip: pull the stop button 10–15 seconds before your station (for example Santa Cruz Intercambiador or TFN) so the driver knows to pull into the correct bay instead of rolling past.
