As summer arrives, the Yilan County Government has launched the 2026 Lanyang Stargazing and Firefly Festival. Following the spring firefly season, the “Starry Sky” nighttime stargazing program begins in June, inviting visitors to experience the beauty of Yilan's night ecology beneath a sky full of stars.

To promote nighttime tourism and environmental education, Yilan organized more than 28 hours of professional astronomy training for tourism industry workers. The program covered astronomy knowledge, constellation identification, and guiding skills. A total of 46 participants completed the training and will serve as future stargazing guides.

The “Starry Sky” guided tours run from June 1 through September 30 and involve 16 licensed tourism operators, including recreational farms, campgrounds, accommodations, and leisure agricultural areas across Nanao, Dongshan, Wujie, Yuanshan, Jiaoxi, and Toucheng.

In addition, Yilan has introduced the “Lanyang Galaxy Night Tour,” combining astronomy, ecology, and local tourism resources to promote sustainable tourism and create new nighttime travel experiences for visitors.
