Rangimairewhenua: The Clearest Water in the World
Upon returning to Nelson, Tor and I spent another night in the Aurora Backpackers Hostel before he left for Christchurch to take finals and I set out on my own for Nelson Lakes National Park. If you traveled New Zealand by guidebook you probably would never hear about Nelson Lakes National Park. Even in Nelson, it is Abel Tasman that gets all the publicity. But Nelson Lakes is truly a gem. I originally heard about the park from one of the DOC ladies on the Hollyford, and then again in the Tararuas. Since I had heard so many good things about it and I was going to be in the area, I decided it would be a waste not to check it out, and I am so glad I did.
Nelson Lakes is out of the way enough that there isn't even a bus that goes by it. To get there I had to take a bus from Nelson to Kawatiri Junction and then hitchhike the rest of the way to St. Arnaud and the park entrance. To give an idea of how out of the way it is, Kawatiri Junction, the closest bus stop to the park is simply a crossroads with a small DOC picnic area on the corner. There are no houses, and the valley gets no sunlight so it is deathly cold. The people at the bus depot were unsure I would even be able to get a ride to St. Arnaud from there because so few cars drive past.
They were almost right. I waited at the corner for almost an hour and saw only 4 cars turn towards St. Arnaud. I was about to start walking the 25km to the park entrance when someone finally stopped. They took me part of the way, and after I had walked a kilometer or two down the road someone else took me the rest of the way. From St. Arnaud I had to walk 5km down a dead end gravel road till I hit the trail head at the base of Mt. Robert. From there I crossed over and around several spurs of Robert Ridge that separate the two Nelson Lakes: Rotoiti (Small Lake) and Rotoroa (Long Lake).
The trail drops from the slopes of Mt. Robert to the Speargrass Creek which it follows for a while before climbing back up the ridge to Speargrass Hut. Speargrass Hut is situated in a beautiful tussock field which extends up the ridge until it turns into bare rock further up. It would have been a lovely place to stay but, if I was going to make it to Blue Lake and back in the 5 days I had in the park I had to keep going.
From Speargrass Hut the trail descends in fits and starts to the shores of Lake Rotoroa. Along the way it crosses a plateau that separates Lake Rotoroa from Cedric Creek and is dotted in small beautiful lakes. Because the ridge is flat at this point, there is very little drainage, so these lakes sit completely still, hidden among the trees, perfectly reflecting the forest around them and the sky above. Even though I was in a hurry I couldn't help but sit on a mossy rock along the shore of one of these lakes and take in the serenity of the scene.
But the quickly approaching sunset forced me to move on down the ridge to the shores of Lake Rotoroa, and Sabine Hut. Sabine Hut sits within a stone's throw of the lake, and has a jetty where water taxis drop off trampers in the summer. I arrived just before sunset and went out to the jetty to sit and enjoy the view across the lake. As I sat there, several eels the length of my arm swam by. After the sun had set I put up my tent by twilight and fell asleep to the lapping of the lake.
The next morning I broke camp and got an early start to Blue Lake. From Sabine Hut the trail follows the Sabine River all the way to Blue Lake and Lake Constance at the head of the valley. It was over 20km to Blue Lake Hut so I had a lot of distance to cover. The day started off foggy, but as I walked the snowy mountaintops began to emerge out of the clouds and show their heads to the sun.
Where the track crosses the Sabine River, there is a small gorge that is without a doubt the best swimming hole I have ever had the pleasure of swimming in. The gorge is small, only 50ft or so long, and about 30ft deep. Where the water flows through, the river deepens substantially making it possible to dive off the cliffs and even off the bridge. The sides of the gorge are overhung so there are little caves carved into the walls. And the best part is that the water is crystal clear. It is possible to see right to the bottom of the river and spot the trout as long as my forearm that patrol the waters. It was still foggy and cold when I passed it on my way to Blue Lake, but I promised myself I would swim in it on the way out no matter what the weather was like.
I stopped for lunch at West Sabine Hut where the Sabine River splits into two branches. From there I followed the west branch past several avalanche paths and up some steep climbs to the famous Blue Lake. Blue Lake has been found to be the clearest natural freshwater in the world. Distilled water has a theoretical visibility of 83m, and Blue Lake comes in just under this, at 80m. The clarity of the water comes from the way the water is naturally filtered. The Sabine River valley was originally lake-less. However at some point a landslide blocked up the river. This formed the much larger Lake Constance which is just up the valley from Blue Lake. But instead of a small river forming to connect the two lakes, the water moves underground through the landslide debris down into Blue Lake. In the process, all of the impurities are filtered out. From anywhere along the edge of the lake it is possible to see straight to the bottom.
Blue Lake has been recognized as an amazing natural wonder since before Europeans arrived. Ngati Apa, the local iwi (Maori tribe), has long held Rangimairewhenua (Blue Lake) to be a tapu (sacred) site. For this reason, swimming and other activities are banned in the lake. However the sheer beauty of the lake and its location among snow-capped peaks make it enjoyable, swimming or not.
At Blue Lake I found a pair of whio (blue ducks), one of New Zealand's many endangered native bird species. Apparently it is very unusual to find whio in lakes as they prefer fast moving rivers, but there has been a pair living on Blue Lake for some time. Though they do not have any spectacular coloring, whio have a very unique call. The males let out a long high-pitched whistle/scream and the females growl or click. I watched them as they patrolled the perimeter of the lake, but when they got close to me they started to call persistently so I took the hint and moved on.
After dropping my gear in the Hut I also made a trip up to Lake Constance. Lake Constance is at least ten times as large as Blue Lake, and is much murkier. However, it still makes for amazing views from the boulder strewn landslide that created it.
At dark I returned to the hut to get a fire going and warm up. As I was doing this I got the hut book out to enter my details in it and found that the last person to be in the hut was Côme! He had made it all the way from the Rees/Dart to Nelson Lakes and we had missed our fourth chance encounter by only 3 days. As usual he left a long, detailed and ecstatic entry describing the incredible beauty he has seen on his trip. I wish I could have been there a few days earlier to see him and hear it in person.
When I had taken down my tent in the morning, I had found that one of the poles was cracked so I decided to prevent further damage and just stay in the huts the rest of the time. I carried the tent for 8 days on the trail and used it only once. If I had only known I wouldn't have bothered to bring it. However this did have the benefit of allowing me to stay in warm enclosed huts for the rest of my trip.
Though I got to sleep early, I was up every hour or so to feed the stove and keep the hut warm. In the morning I was tired, but the stove was still going so I was able to make breakfast in the warmth. After making one last trip down to Blue Lake I headed back down the valley. This time though I stopped at the gorge to swim. After 5 days of sunshine, three in Abel Tasman and two in Nelson Lakes, it was overcast again, and by the time I made it to the gorge it was drizzling. But I could not go back to the States without at least jumping in at such an amazing swimming hole so I climbed down to the water and took a quick splash. It was icy cold but so refreshing. I hope someday I can come back and swim there when it is warm and sunny out.
That night I stayed at Sabine Hut and it poured down rain. The next morning it was still overcast but not raining, however by the time I had made it to Speargrass Hut around lunchtime it had started up again and I spent the rest of the day in the hut reading. I was worried that all the rain would swell the Speargrass Creek and I would have to wait out the weather, but it didn't seem to have much effect at all, and when I made it back to the trailhead my boots weren't any wetter than they had been on the first day.
When I got back to St. Arnaud and stopped in at the DOC office to get the bus company's number it was the first time I had seen a human being in three and a half days. It was a lonely trip for sure, but not in a bad way. Solitude seemed to amplify the grandeur of what I saw around me. After a day I got used to the fact that there was no one else to talk to, and I didn't even notice it anymore. I sang to myself and stayed busy reading at night. I began to think about and understand myself in a way that is impossible in the presence of others. Eventually the fact that I was alone didn't even cross my mind. When I returned to the civilized and populated world and others were surprised that I was alone for that long, it seemed strange to think that it felt so normal and natural to be alone. I am still surprised I was able to stay sane.
While I would have to say that I have much more fun backpacking with friends and having lively conversation at night, being alone in the wilderness is an experience I value very highly. It gives me a sense of independence and accomplishment and self-understanding. It is a different experience entirely, and provides a different kind of reward. Less entertaining perhaps but equally meaningful.
My trip to Nelson Lakes will be remembered as one of the highlights of my time here. It is a place of singular beauty and the fact that it is off the tourist radar only makes it better. For anyone who is thinking of traveling to New Zealand, put this stop on your list. It is well worth going out of your way to get there.
