If I travel from Taipei to Taichung, can I turn back on the same day?

You can turn back on the same day, but Gaomei Wetland is more suitable for watching the sunset, so take a bus to Taidonghai University after lunch in Taipei, then go to Gaomei Wetland, and return to Taipei after dinner should be enough time... I hope it can help you

You can go back and forth in a day by high-speed rail, but it's a waste of money.

Yes, it takes 1 hour to get to Taichung by high-speed rail, and 2 hours by passenger train.

Take the fastest high-speed rail, and you will arrive in Taichung in 45 minutes. There is no problem going back and forth in the day.

From Taipei to Taichung, I only go to Tunghai University and Gaomei Wetland. Can I return on the same day? It’s not impossible, but time is very tight. It is recommended that you take the high-speed rail to Taichung, take the first train departing at 06:26, arrive at Xinwuri High-Speed ​​Railway Station at 07:13, and then go to the nearby Taiwan Railway Wuri Railway Station and take a shuttle bus , about 40 minutes, to Qingshui Station, transfer to Juye Passenger Bus No. 178/179, and get off at Gaomei Wetland Visitor Center in about 1 hour. <br/>178 Qingshui-Gaomei-Gaomei Wetland<br/>Departure time from Qingshui Station on weekdays: 06:00/07:20/10:30/14:20/16:20/19:00, only 6 times , there are not many trains;<br/>179 Qingshui-Sanmei-Gaomei Wetland<br/>Departure time from Qingshui Station on weekdays: 06:40/08:40/11:20/15:20/18:00<br/ >When returning, take Juye Bus No. 167 at Qingshui Station to Fengjia University
