What are some good hikes to do with a 6 month old in backpack carrier?

Bridal veil, Yosemite falls are close by there similarly many hikes all over the park you can explore

happy isles trail too

Go up to the Taft Point lookout walk. Its a couple of miles through woodland and some of the most spectacular views about. Walk is easy. If you want a longer walk catch the bus to Glacier point and walk down to the valley via the Panorama trail. Will take about 6hrs though. You'll pass waterfalls and awesome views.
