Holi marks the arrival of spring and the triumph of good over evil, rooted in the legend of Prahlad and Holika — but on the ground, it's simply one of India's most joyful, chaotic festivals, where strangers become temporary family through color and water. You'll spend the day with a local Indian family, joining the throwing of dry and wet colors, water balloons, and Bollywood music, alongside festival foods like dahi bhalla, chila, gulab jamun, and thandai. Tip: wear old clothes you're fully prepared to ruin — the colors used are genuinely permanent on fabric. Consider applying oil to your skin and hair beforehand, since it makes the color easier to wash out afterward. Waterproof phone pouches are worth bringing if you want photos during the celebration itself rather than only before and after.
