Sunrise, Sunset, and Night Skies

Several times each year, the park opens its doors early and keeps them open late. During these hours, we encourage visitors to experience the Tumacácori mission grounds during the soft light of early morning, twilight, and evening. On some occasions, celestial events may be occuring with special interpretive programs. Artists and photographers particularly enjoy these opportunities.

Why Offer Night Programs?

In 2018, Tumacácori was officially designated as the 100th International Dark Sky Park by the International Dark Sky Association (IDA). This certification comes with rigorous monitoring, light pollution testing, and a commitment to protect dark sky values for wildlife and humans.

The park's outdoor lighting, for example, uses IDA-approved shields. Research into bat populations and other wildlife inform decision-making. Interpretive programming shares these ideas with the public.
