Planning for Yangmingshan

Hello, I am seeking advice on planning a 1 day trip to yangmingshan and would like to know what are some of the ways to access the place.

My understanding at the moment is: Tours: Ease of Planning but very rush

Self Planned: I check google it seem to be possible to go around yangmingshan by Public Transport. (If anyone knows more or have experience on this i would like to know)

Hire a driver: private tour like? I don't really want this option as i don't have alot of budget feel expensive.

Any trip ideas or suggestions for Taipei/Taichong is also welcomed. At the moment I just saw Yangmingshan so going step by step 😆.

Thanks in advance 🙏
