For a first-timer in 2026, 7 to 10 days is widely considered the "sweet spot" for Tuscany. A supportive peer "pacing" breakdown: I recommend spending 3 days in Florence to cover the Uffizi, Accademia, and the Duomo, followed by 4 to 5 days in the countryside. With a rental car, you can base yourself in a town like Siena or Pienza and take day trips to the Val d’Orcia, San Gimignano, and the wineries of Chianti. If you only have 3 or 4 days, you will likely only see Florence and maybe one hill town, which misses the "slow life" essence of the region. By 2026, Tuscany has seen an increase in "experience-based" tourism, so budgeting extra time for a half-day cooking class or a leisurely truffle hunt in San Miniato will make the trip feel much more authentic than simply rushing through a list of cathedrals and museums.
