Hi all, I hope you are well.
Please forgive me if I’m repeating questions that have been answered on the forum. I have searched around on the forum and I’ve not been able to find answers to these questions specifically. Some times the answer is close, but not exactly what I’m looking for e.g. “Isobutane is better for colder temps” is fine, but it doesn’t answer the question of whether I should buy it for the Berg, or whether Eiger is “good enough” etc.
Three of us are looking to do the GT at the end of March. I’ve been doing a lot of research, and buying, to prepare for the hike. We are a decently fit and experienced group, but none of us have done much hiking in the central Drakensberg. I would have preferred to be able to a shorter “practice” hike in the Drakensberg before trying the GT, but life just isn’t being very accommodating.
The longest hike that I’ve done before would be the Naukluft (one and a half times, got sick the second time round, did a write-up here on the forum). We are looking to do the GT in 10 days if possible.
I’ve been reading up as much as I can but I do still have a few questions that I would be very grateful for any assistance with:
How much gas would you recommend? I know how much I would usually take on a 10-day trip, but I’m not sure how to account for the lower temps and higher altitude. We will be using pretty standard stoves. Some kind of Firemaple stove that I’ve been using for a few years now.
Should I spend extra and buy MSR Isopro gas, or can I get away with Eiger? Possibly a mix (e.g. 1 bottle ISOPro for when it’s really cold and 1 bottle Eiger for the warmer days).
We will be taking maps, a compass, and a Satellite phone which can give GPS co-ordinates. But I’m intrigued by the offline GPS navigation apps that you find on cellphones these days. Do you have any recommendations about which apps work best (cheapest?)?
I have found a few lists of co-ordinates, as well as a GPX file or two, but I’m not sure about whether they are actually any good, or the best. Does anyone here perhaps have GPX file that they know to be good and detailed? Especially if it’s one with a route and not just a set of GPS markers.
Thermal base layers. Which thermal baselayers would you recommend? Base Layer Bundle Men - Core Merino could be an option, but they are on the thinner (125 g/sm) side, and also quite expensive. I’m mostly interested in the baselayer for sleeping, and not really for hiking in, if I can help it.
Any other advice, remarks welcome!
