Located in the heart of Trivandrum, the Priyadarshini Planetarium is one of the most versatile planetaria in India, offering a mesmerizing astronomical experience. The best time to visit the planetarium is during the months of October to February when Kerala's climate is most pleasant. During this period, the weather is typically cooler and less humid, making it comfortable for tourists to enjoy not just the planetarium, but also to explore the surrounding attractions in Trivandrum. The Priyadarshini Planetarium remains a popular destination for school trips and educational tours, so planning your visit on weekdays can help avoid larger crowds of students.
Apart from the favorable weather, visiting during the winter season also coincides with several cultural festivals and events in Kerala, which could enhance your overall experience. The planetarium usually operates from 10:00 AM to 5:00 PM, with various shows scheduled throughout the day. Before finalizing your visit, it's advisable to check the latest timings and show schedules which might vary during special public holidays or events. Additionally, ensure to check for any maintenance days to avoid disappointment.
