Apple is hosting its annual National Parks activity challenge for Apple Watch users on August 23, 2026. To earn a special award, participants must complete a hike, walk, run, or wheelchair push for at least 20 minutes on that day. Successful participants will receive animated stickers for use in the Messages app, a common reward for these challenges. This event is part of a broader August initiative by Apple to celebrate national parks, which includes Apple Pay donations, themed content on Apple TV, Apple Music, and curated books and podcasts.
