The weather forecast for Saturday 9th April 2011 was for wall to wall sunshine in the west, with a day more akin to a Summers day in the pipeline. Peter and I decided to do something big to get back into the swing (my first munros of 2011), so this pair of Beinn Achaladair and Beinn a'Chreachain looked exactly what we were after.
The day started off with mist all the way from Glasgow to the Bridge of Orchy area, but it was obvious that would burn off. Being into photography, we stopped off at Loch Lomond and then Loch Tulla on the way to get some landscapes.
Time to reflect at Loch Lomond:

Another nice reflection - Creise:

It is simple to find the start of this walk, at the end of Loch Tulla, turn right (if coming from Glasgow) into a road marked Achaladair, which takes you to a cracking carpark created by the accomodating farmer (I've since read there is an honesty box for donations, so feel guilty that I never saw it!). There is an old ruined tower here.

Very importantly, at this point you need to decide whether to tackle the circular route in a clockwise or anti-clockwise direction. More by accident rather than design we chose the latter, so headed straight up to the Beallach between Beinn Achaladair and Beinn an Dothaidh. In retrospect, I think the clockwise route would have been a better choice, as you walk towards the munros in Glen Lyon. There is one very steep area in this walk and it is just beside the top of Beinn Achaladair. We descended this, it was pretty easy, looking back it looks much steeper. Ascent would be fine too I reckon - there is no exposure.
So, we walked over the bride at the railway line and up the well defined path. This reminded me of Coire Leis with Beinn an Dothaidh being the North face of Ben Nevis and Beinn Achaladair being CMD. Unlike the route at Nevis, you follow the Coire Achaladair all the way to the top. We had a break for lunch behind a large rock, sheltering from the wind sweeping over the top of the beallach.

Then it was a left turn and an ascent along the sweeping ridge of Beinn Achaladair, reaching the first 1002m top soon thereafter. It was at this point that we realised that Beinn a'Chreachain was a fair old distance away and this was going to mean a MAJOR walk back to the car! An older couple we'd met- the woman was 69, decided that was too far for them, so accompanied us to the true summit of Beinn Achaladair (1036m) and then doubled back.

We began the decent, beside the impressive cliffs to the Meall Buidhe hill, which separates the 2 munros. This is quite steep but not exposed and a great deal of fun. The drop is 700 feet and then you have to ascend Meall Buidhe, walk along another high ride and then only a slight descent to the start of the final push up Beinn a'Creachain to attain the 2nd munro summit of the day, the higher 1081m Beinn a'Chreachain. Elated now that the climbing is over for the day and we have the joy of the long walk back!

The descent from Beinn a'Chreachain:

Just down from the top, we catch our first view of the very impressive Lochan a'Chreachain, glinting in the evening sunshine. We descent down to the burn, but get caught between 2 burns and have to make a tricky descent, burn crossing and ascent.

Looking back up the hill:

The route is to follow the burn all of the way to the railway line and then duck down and go through the wee tunnel under the railway. After this, it was a bit of a nightmare, sqwelchy bog in amongst the scotts pine trees. We crossed the river, again no mean feat (just wet feet!) and headed for the obvious land rover track. This splits and heads over a wooden sleeper bridge to head back to the farm carpark. I've never been so glad to see the car!
We started around 11.30am and finished at 8.30pm, it was still daylight. So, a good 9 hour circular walk of 19km and my legs are telling me all about it as I sit here are write this trip report.
My advice would be to head along the farm track and do the clockwise circuit rather than head for the beallach.
