Dajia is one of the most pleasant places in central Taipei to get on a bike. The path here is part of the city’s long riverside bikeway network, which runs for many kilometres along the Keelung, Tamsui, and other rivers behind the flood walls — flat, car-free, and well surfaced. With a YouBike (Taipei’s public share scheme, paid by EasyCard) you can pick up a bike near Yuanshan, ride upstream past the flower fields, and continue toward Dadaocheng Wharf or back the other way without ever fighting traffic.
Because the park sits below the city’s flood walls, you enter through gated ramps and underpasses rather than a single front gate; once inside, the river opens up on one side and the city skyline rises on the other. It’s an easy, forgiving ride for all ages, which is part of why families and casual cyclists love it.
