Few things you need to ask yourself first: How many days do you have? Do you want to do the sunrise? Do you want to take the Alishan Forest Railway?
These are all important to think about because the nature of the logistics will dictate how your itinerary looks like.
If you’re doing Alishan on your own, it would be very challenging to do Alishan in one day. Even if you tried, you’d be throwing the sunrise out the door and you’d only have enough time to do the forest trails.
There are several ways up to Alishan but these are the most common and preferred methods. Alishan Forest Railway Train Tourist Shuttle Bus Local Drivers
My recommendation would be to stay inside the park if you can afford it as it saves you the hassle in the morning for sunrise as the shuttle ride is included and so you don’t have to wake up that early in the morning.
