If you only visit the temples while sightseeing, spending half a day in northern Taiwan and just strolling through the temple grounds with no intention of entering or exploring further, it might be feasible to cover some decent ground but the actual number depends on various factors such as how many temples you plan to visit.
Assuming an average time spent at each temple is around 1-2 hours (depending on whether you enter certain buildings, watch a show/presentation, etc.), and considering the distances between them are relatively short in northern Taiwan (e.g., Yehliu Geopark to Jiufen Old Street), it’s possible to see maybe 3-5 temples within half a day.
For example:
- Beiluo Temple + nearby Qingshui Temple = 2-4 hours
- Yehliu Geopark to Jinguashi area (e.g., Wufengou Cape, Qingyuan Cliff) = 2-3 hours
Please note that these are rough estimates and actual time spent may vary greatly depending on individual pace, interests, and other factors.
In summary, it’s plausible but not a huge number of temples you can realistically cover in half a day.
