From my experience back at 2019, the cheapest place to apply for a ticket is at sector Pelouse Jove (between 30€ and 35€, only raceday, attendance aged 16-30). Pelouse Jove is located at turn 4 ‘Repsol’, so you get to access there from Gate 7, this means: take at least 30 min of walking time from the bus stop to the gate if you consider the bus service, plus 10 min of queue, and another 10-15 min to walk from the gate to the Pelouse Jove area which is located just at the other side of the bridge you certainly gonna find. Don’t miss the chance to watch warm-up events all included: F2 and Porsche Cup. If the weather is good, consider carrying a lot of water, sunblock, sunglasses, a hat, a mat, and food of course… because it will be hot!
Important tip: the best place to sit within Pelouse Jove, from my point of view, is the closest side to turn 5, next to the Carlos Sainz’s grandstand. Why? You get a giant screen in front, a decent view of the small straight line between turns 4 and 5, and even a little part of turn 2! Make sure you arrive early enough to the circuit, so you can secure ‘spots’ (there are no seats), because it’s the most crowded place!
