On the way to Milford Sound, there is a tunnel about 25 minutes out. It is narrow, so traffic can only flow one way. There are 15 minute periods where the traffic alternates. We had plenty of time before our cruise tour, so we stopped at the parking lot and took a walk. This picture only shows the waterfall we were walking to. Subsequent pictures will show why it was so neat and a destination. The walk began with hiking on a regular trail, then traversing a huge expanse of loose rocks and boulders (some 4x bigger than me).
