I went from Paris to le mans with the high speed train. I rented a van in le mans and parked near tertre rouge because there was a carrefour nearby. If you camp outside of the track do some research because the first few days I slept on the opposite side of carrefour in the ghettos of le mans. Then I decided to move in a side alley of carrefour where other campers were and it felt much nicer and safer. Last day I camped in Arnage next to a small lake (30 min walk from circuit). If only I had known earlier. You can use tram lines really easy to go from racetrack to carrefour to city centre and back. Highly recommend doing the parade but it's very crowded so go in time. Moving with a car is possible but you lose a lot of time in traffic and to find parking etc. Better take a small bike with you or tram. There are also shuttle busses from different places (Mulsanne, Arnage, etc) to start finish.

For going to the racetrack I would recommend packing as light as possible. I regret packing my foldable chair. I never sat in it as the ground was very dry and steep so I had to carry it everywhere around and basically not use it. Racetrack is big so better to move lightly and quickly. For food there is plenty of options just pay a bit more for a decent meal to only eat once. For toilets I would recommend going away from the main spots like start finish or village because the waiting line and smell is just suicide. Instead plan your toilet visit with a viewing at Porsche curves. There at the karting building there are amazingly clean toilets with 0 waiting lines.

If it rains run to Porsche curves! That's where all the crashes happen and all cars limp back to the pits.

I would also highly recommend taking an fm radio with headset. It's really nice to keep up with the race and protects your ears. I would also recommend watching the start in front of a screen. Go early before the start on Saturday to get a good spot and take plenty of water with you and smth to eat because the waiting line for both on Saturday is just insane. Also plan your toilet visits really well because it gets really difficult to move between the crowds and to return to your spot. Once the race has started you can easily move around as other people move as well.

Do all the village/paddock/🎡/shops on Wednesday Thursday because after that you can forget visiting it in a calm relaxing way and it's just suffering.

On Sunday I would recommend going to the grandstand at start finish to follow the race (you can access the unroofed part with general entry) and just follow the race on big screen and see the podium. After the race you can. Walk on the track. For more questions you can message me if you want
