Today we left the condo by 6AM to drive about 300 km from Queenstown over to Milford Sound.
The GPS led us on a wild goose chase, 45 minutes into the trip we realized we were traveling in the wrong direction. Just what we needed so early. We had pre-booked/paid for the tour. Leaving so early gave us a little extra time for stops along the way. Even though the speed limit is 100kph there is little chance of going that fast. We made it in the nick of time.
Milford Sound is one of 14 Fjord's located on the western side of NZ's southern island. We left for our cruise at 12:30, and were told by the nature guide on board that this was the best weather they have had in the previous 8 days. We were also fortunate just to get out to Milford sound. About a week prior to our cruise, there were heavy rains that caused rockslides that closed the roads out to Milford Sound for a few days.
Milford Sounds was beautiful. The mountains that form the Fjord ranged in height from 1500 meters to 2000 meters. The depth of the water in the Fjord was over 700 meters deep. At one point we were only about 50 feet from the side of the side of the mountain, and the water was still 130 meters deep.
The enormity of the Fjords is difficult to show with photos. In order to really experience their size, one must be surrounded by the Fjord. Cruising along the water next to a mountain that is 1.5 miles high can make you feel pretty tiny. Other boats look like tiny bath toys when seen next to a 150 meter waterfall.
Our cruise had a nature guide on board who gave us a lot of great information about the Fjords and the area. Milford Sound gets about 7 meters of rain a year. All of that rain makes a lot of great waterfalls on the mountains. Because of all of the rain, and because the fresh water from the rain is less dense than the saltwater from the sea, the top 5 meters of water in the Fjord is actually a layer of fresh water on top of the saltwater.
Looking at the mountains, one has to wonder how all of the trees and foliage can grow on the side of the mountain. Only about 25% of the trees are actually anchored into the side of the mountain. The other 75% of the trees and shrubs are anchored into these roots. It's a bit of a precarious system. Occasionally the system fails, and there is a landslide of trees that washes down the mountain side.
Geologically, the area of Milford Sounds is quite active. The Fjords were formed by plates pushing up on each other. The mountains are continually growing at a rate of the thickness of a fingernail per year. Additionally, there are approximately 2000 earthquakes in the area per year.
The cruise lasted 2.5 hours. We made it out of the Fjord, into the Tasman Sea, and then back to port. It was a great cruise and a great day trip.
