My two cents worth is based on 4 years of riding in Taiwan and a bunch of really good memories. Sometimes I ride 30k along the Da’an Riverside to Tucheng to get the MRT for an evening in Taipei, then cruise home at midnight in absolute silence until i get to Daxi and climb up out of the river valley. I’ve followed the river from Daxi all the way to Datong into downtown, and back too. Or I may ride to Fuxing and back, or Baling if I feel frisky. I like hwy 7 from Daxi to the east coast too. Go to Ilan/Jiaoxi for Sat. night at the hotsprings, come back Sunday through Pinglin - 250k for the w/e is nice.
I end most of my rides with a cold beer watching the sun go down on the lake at Longtan. I’ve ridden around the island 2x, done IM Taiwan down in Kenting in 2015. I rode up to Dayuling from Ilan once by mistake. LOL then rode down to Hualien and hitchhiked with the bike back to Longtan. Haven’t done it all, but have hit the high points I think. I’d say it is a cyclist’s paradise. It’s what you make it.
I rave about Taiwan for the bicycling opportunities every chance I get - to my friends, to fellow triathletes at races, and anybody else when the topic arises. I love the heat, even the humidity, because - no snow! (I’m Canadian. Cycling gets tough for half the year back home in The Great White North.)
I live in Longtan and the roads here are fine, surface, lines, shoulders, all good. The variety of terrain is terrific - I can ride up a mountain just a few klicks from my front door, or rip along 114 through Xinwu to the seacoast at Yongan and back in an afternoon. Luoma Lu, around Shihmen Reservoir 65kms, is riding in a forest with curves and hills galore. Barely any traffic. I climb LaoZhuang Road above Longtan and cruise down into Yangmei for a burger at Ronnie’s, or on Sundays for breakfast. Unless I want to coast down through the tea plantation to hwy 20, then climb #115 back to Yangmei, That’s good too.
