Arthur"s Pass Base Weekend: Otira Valley, 3rd January 2020

 A return to the Otira Valley, Arthur's Pass NP...

Karen and I spent a couple of days in Arthur's Pass National Park in early January and while there we went for a number of short walks in the area. We had some good weather for a change...it was cool but at least it didn't hose with rain like the last two times we have come up here.

One of the trips we did was up the Otira Valley to the footbridge half way to the head cirque...the last time I was up here was back in 2016 and I wanted to show Karen what a nice valley it is. It is sub alpine and alpine terrain up here...rocks, water and flora suited to the climate. 

Otira Valley Track: a scree slide about half way to the bridge

The Otira Valley Track is great in the summer but incredibly dangerous in the Autumn/Winter/Spring as it is flanked on both sides by +1900 meter high ridges. They accumulate a lot of snow and are prone to sudden and devastating avalanches. This makes the Otira Valley a no go zone for the colder snowy months of the year.

This is a must do for any slightly adventurous visitor to the park and you are assured of a good work out if you head up the valley. Anyway...lets see what the track looks like...

Tramping to the Otira Valley bridge

The track starts on the left side of SH 73 just past the Arthur Dobson Memorial on the top of Arthur's Pass. It is signposted and has space for about 6-7 cars. The first kilometer is a moderately step climb and it starts right from the first step.

The track quality is good to start with and then becomes a bit rocky and eroded up the track. The day was overcast and cool but we had on rain or overly strong wind so really it was good conditions for a stroll up the valley. 

The views up and back down the valley get better the higher you climb...and the encompassing ridges and high peaks emphasize how minuscule you are in the greater scheme of things...

Starting to sidle along the side of  Goldney Ridge

We were visiting past the best time of the year to see the alpine flowers but there were still a lot of mountain daisies and other flower around. We have had a late and cool summer this year so it has knocked the cycles of the plants around a bit.

There are not a lot of trees up this valley but the herbs, shrubs and  multi colored alpine plants make for an interesting backdrop. You often see Chamois and Thar up this valley as they love to eat these succulent alpine plants...sadly we saw no such beasts on this trip.

Mountain daisies along the Otira Valley Track

This valley was shaped by the Rolleston Glacier and by the Otira River....if you were here 20 000 years ago the whole valley would have been filled with an ice sheet that stretched out past the Taramakau Valley 20 odd kilometers further west. That is why the valley is so steep sided...the ice carved the sides clean and it takes a long time to erode. 

Once the ice melted the river got to work gradually pushing gravel down the river bed...an action that continues to this day.

We passed several areas of mountain daisies they are most prevalent in the mid reaches of the Otira Valley as they have an altitude and climate range where they grow. They add a nice touch of color to the usual greens, browns and oranges of the alpine plants.

Sub alpine flora and flowers along the Otira Valley Track

There are many different rock forms up this valley and the colors of these range from grey to brown, orange and range from small pebbles to huge chunks of rock the size of a multi story house.

The other thing you have in the valley is water...there is water everywhere with waterfalls, seeps, creeks, streams and the Otira River itself. If you walk up here on a calm day the sound you will hear is water dripping, falling and flowing. It makes an excellent back-drop to your tramping journey...

It take from one to one and a half hours to reach the bridge over the Otira River...this is the end of the marked track. From this point onward you require outdoor navigation skills as you make your own way up valley to the head cirque another hour away.

We were pleased to reach the bridge and were looking forward to lunch, a drink and a sit down. 

Lunch at the Otira Valley footbridge

We had decided beforehand to only walk as far as the Otira Valley bridge as it was due to rain later that afternoon. The area around the bridge is an excellent spot to stop out of the wind for a break or lunch so we found a cosy position and settled down to eat. 

Precariously balanced bridge on the Otira Valley Track

The water up here is OK for human consumption if you end to refill..personally I would still treat it as there are isolated cases of Giardia etc. in the park all the time. It is the people...Arthur's Pass is very popular so there are always crowds of people around and where you have crowds you have problems.

If you come up here in autumn or late spring this is the absolute furthest you should go...you are relatively safe up to this point but past the bridge you are in danger from rock/ice/snow falls off the side of the very unstable Mt Philistine. Even in summer you must exercise extreme caution as even a summer snow fall (they happen from time to time) is a candidate for an avalanche.

Karen and I crossed over the bridge after lunch to takes some photos...there are good vistas up to the western side of Mt Rolleston and also down the valley you have just walked up. 

Goldney Ridge is avalanche prone in winter...

Some sub alpine plants growing near the Otira Valley bridge

The Otira Valley bridge is a rickety affair..it is stable enough but the only thing holding it between the two boulders it sits on are a couple of cables and a couple of bolts. There used to be a more sturdy metal bridge up here but it got damaged beyond repair in a massive storm and was never replaced. 

Take care when crossing as a fall off the bridge would not be the making of your day...

We could see parts of Mt Rolleston from the talus field on the true left of the Otira Valley...there was still some snow on this side of the mountain even this late in the year. The snow was all orange as are snowfields on most mountains in the South Island as ash from the huge Australian bush-fires have dusted the snow.

If ever you needed a sign of the inter connected nature of the Earth the smoke filled skies, smell of wood smoke and ash from fires over 3000 kilometers away are a real portent. This is what climate change is going to look like as we go deeper into the 21st Century.

...lots of loose Weetbix rock on the ridges of Mt Philistine...don't squot Jon like a pompkin!!!

 If you are going up here bring a cooker and have a brew...it would be an excellent spot for a bit of outdoor tea making. I wish we had thought to bring one with us...my light cooker and Ti pot are very light so it would not have been a burden.

 We spent about 20 minutes around the bridge and then packed up our gear ready for the walk back down the valley.

Heading back down to the Otira Valley car park

We set off back down the valley to the car park just past 1 pm...it is a little quicker to walk down the valley than up so I estimated it would take about an hour. This turned out to be just about correct as we got to the car around 2.15.

We made good progress down the track and passed quite a few people who were heading up valley. Personally I would plan to visit earlier in the day so as not to become be-nighted in the Otira Valley...even with a head lamp this track would be a good candidate for falling and breaking your leg etc. tripping over a rock. 

Exposed rock where the Otira Valley Track has eroded

As you head back towards the highway you have some spectacular views of the mountain ranges on the far side of SH73. There are tracks to many of these peaks mostly sidling along the sides of the ranges from the Temple Basin skifield.

I intend to walk up to Temple Basin again some time in the near future as I am walking tracks in Arthur's Pass for my other blog Arthur's Pass Adventures. Eventually I hope to walk all the tracks in the National Park but I am aware I am getting older every year so we will have to see...

After 45 minutes you get to a spot where you ca look down onto SH 73 and the car-park at the start of the track once more. I was pleased to see the car was still there...I dont think i would leave my car there overnight as it would draw the unwanted attentions of the scumbag vandals who regularly break into cars along this highway. 

It is perfectly fine for a day walk as there is a lot of traffic dissuading them from villainy.

SH 73 and Pegleg Valley from the Otira Valley Track

...its big country at the head of the Otira Gorge...

The last kilometer down to the car park is moderately steep and rocky so just take some care when walking along he track. If I am going to hurt myself it usually happens over the last kilometer when i am tired and not paying attention. 

Case in point...I fell over 100 meters away from Whariwharangi Hut on the Abel Tasman Coast Track in October and it has only just healed. Be mindful of what you are doing right to the end of the tramp...

Yes....the silver Surfer is still there....Otira Valley Track

We passed a European couple around the point in the photo below and I commented to Karen about how stupid it was heading into a high alpine valley at that time of the day. They were only carrying the clothes they were in and didn't have any warm clothing etc. Sure it is summer and day light savings but it is still a bit dubious starting out on a tramp that late in the day. 

Better to be well prepared and cautious than dead....

Approaching the end of the Otira Valley Track

DOC car park at the start of the Otira Valley Track

It was great to get back up the Otira Valley after several years...this really is one of the best short walks in Arthur's Pass National Park. Its not that difficult a track..you just need to be prepared and have the right skills and gear if going past the bridge. I really must come back here soon and show you what its like in the cirque under the western face of Mt Rolleston...preferably before Autumn arrives. 

Camping trip anyone?

Access: Track starts just to the west of Arthur's Pass on SH73, there is a small car-park on the left of the road
Track Times: 1.5 hours to the foot bridge over the Otira River, another 1-1.5 hours to the cirque at the base of Mt Rolleston, same to return.
Miscellaneous:Extreme avalanche danger in spring/winter along all of this track. Do not enter the valley in winter after heavy rain or a late spring snow storm. I'm really not joking...it looks OK but is awesomely dangerous until the snow pack melts....people have died in avalanches in this valley!!!
