Hi there,
moet36 wrote:1. We have hiked a lot around the world, but almost all on decently-marked trails. We are not experienced at using OS Maps or Compasses, but are planning to buy them and try to learn. Is it feasible for us to try and do any or all of these 3 hikes on our own, or should we look to hire a guide? From reading, it seemed that Ben Alligin has a decently marked path, but we were less sure about Beinn Eighe and Liathach.
Route finding on Alligin is indeed pretty straightforward, though there are multiple minor variations on the scrambling sections, and it's not always obvious which is the easiest. On Liathach there are possible problems leaving the main summit in the right direction (the ground is so bouldery that the path is not very evident) and locating the start of the descent path. On Beinn Eighe the only potentially tricky bit is finding the descent off Coinneach Mhor.
moet36 wrote:2. This is undoubtedly personal preference, but which of these do you think is the greatest experience?
Personally, I would rate Alligin top (and possibly my favourite hill walk in Scotland), then Liathach, then Eighe. Liathach is the most technical and spectacular, but Alligin is a more aesthetically pleasing circuit, without single dull moment. Others may of course disagree!
moet36 wrote:3. How similar are the views and experiences? Is it worth doing all 3, or given we have limited time, is doing maybe 2 of them sufficient to get the experience of the area?
On a global scale, the views and mountain architecture are quite similar. The chances of you getting 3 good weather days in a row is not very high, in any case!
moet36 wrote:4. We are all too aware of the variable weather in the Highlands. Can any of these hikes be reasonably attempted in wet weather, or should we only try if the forecast is dry and clear?
They are possible in wet weather, though is still better to stick to the ridge crests and avoid bypass paths which tend to get slippery. If the cloud is down, and you aren't going to see anything, then you might ask yourself whether there's much point, whether your navigations skills are up to it, and whether you would be better off doing a lower level walk instead! Having some Plan B's is always a good idea in Scotland....
Hope you have a great trip.
