How to Plan an Outdoor Birthday Party in 2026
The best outdoor birthday parties take advantage of open space for active games, use weather-resistant decorations like balloon garlands and fabric bunting, and include a weather backup plan (pop-up tent, covered patio, or rain date). Popular venues include backyards, local parks, and community pools. Plan for 2-4 hours with a budget of $100-$500 depending on guest count and venue. Always check park reservation requirements and bring sunscreen, bug spray, and plenty of water.
