Sharing details I couldn’t find in advance…The 21-mile route that starts in Arrowtown follows the Arrow River Bridges trail, then turns onto the Twin Rivers Trail, and finally the Frankton track by waterfront near the airport, on down to downtown. There were 2-3 short segments on country lanes used by cars, but I never encountered a car. No restrooms at check-in shop in CBD, and in Arrowtown you have to go away from the trail entrance a bit to find the public toilets. The quality of the trail is pretty much as advertised, almost all groomed gravel. There are many hairpin turns to watch out for. I went on a sunny day, but wish I had brought sunglasses that transmitted more light, as you’re often in the shade while you’re navigating turns and such. My e-bike was a light duty mountain bike with front suspension only and a slightly cushy seat. The power was good - 3 levels - I used level 1 almost all the way, and level 2 only for a few of the steep hills. I am not a super-serious biker and almost always ride on roads - but I was able to do this trail in 1.5 hours (plus one brief water break stop). This trail requires enough attention that you aren’t seeing the scenery very much - so I could see dedicating more time to the ride if you want to stop more often and take in the scenery. The whole thing is a great value for the money. It’s a great ride - enjoy!
