1984 Zanvoort, as a four-year-old, with the whole family, back in the days when that was still affordable (I estimate 16 euros for a GA ticket, non-inflation corrected). My first weekend as a fan was the 1994 Belgian Grand Prix, also with the whole family, which was a bit of a splurge but we did it instead of our usual camping trip which couldn’t go through that year. My final weekend to date was the 2010 Belgian Grand Prix, which was an absolutely fantastic experience, in spite of the weather (got a bit brown pushing my brother’s car out of the mud as we parked in one of the ‘official’ grass field in Francorchamps).
