8.2-mile ride from Sentinel Bridge along the Valley Loop Trail that parallels Northside Drive to the beach near the El Cap Crossover Road. Our intention was to take the El Cap Crossover Road to Southside Drive to do a complete loop, but the smoke was so bad that we had to turn around and go back.

From there we biked back on the bike path that paralleled Southside Drive, passing the cute little Yosemite Chapel along the way.

18.6-mile e-bike ride from Lake Hawea to Lake Wanaka. The start of the ride pretty much followed the Hawea River Track for the first 9 miles, along a riverside trail with beautiful landscapes along the way. At around 9 miles (the halfway point) we came to the Clutha River, where we had to ride over a narrow bridge, with about 2 inches to spare on either end of my handlebars. After that, we were on the Outlet Track, a beautiful dirt trail through a forest, which traced the shores of the Clutha River. As the trail narrowed in sections to single track (only one bike wide), I once again questioned how (and why?) my son was able to get my granddaughter through here in her little trailer behind him. From there we continued along a very picturesque lakeside trail leading us back along the lovely shores of Lake Wanaka into the town.
