Apple will launch its annual National Parks Apple Watch activity challenge on Sunday, August 23, 2026, to celebrate national parks across the United States.

Apple Watch owners can earn an Apple Watch activity award by completing a hike, walk, run, or wheelchair push lasting 20 minutes or more on that date. Earning the award grants users animated stickers for the Messages app.

Alongside the challenge, Apple typically offers national parks-themed content in August, including an Apple Pay donation program, Apple TV content, Apple Music songs, books, and podcasts.

The challenge encourages outdoor activity while supporting conservation efforts through Apple's ecosystem.
