Juan Castro Blanco National Park is a protected area in Alajuela Province, Costa Rica that conserves montane and cloud-forest ecosystems and the headwaters of multiple rivers. It is notable for protecting high-elevation forest and important freshwater catchments.

The park offers trails, birdwatching and opportunities to see montane forest habitats and waterfalls. Recreational use is primarily low-impact activities such as hiking and wildlife observation rather than large-scale tourism.
