Intro: A week in Dunlewey.
We took up residence in the Dunlewey Hostel for a week with the aim of doing some new routes in the Derryveagh Mountains (Slieve Sneachta), Errigal, and Muckish, travelling further afield if the weather improved.
There were a few other people in the hostel but we had it to ourselves more or less. It was fantastic. The facilities are first class, especially the drying room and the kitchen. We were given the run of the place by Erin and her team and we are very grateful to them.

Day 1 | Errigal North west Ridge: 20-10-2018
Nuala Finn, Gerard O’Sullivan, Ciarán Walsh.
Start time 10.30
Forecast was fairly good. Ireland lay at the top end of a slack depression with a very light band of rain covering the North West, very or light wind. It was lovely and clear “at ground level” but cloud over remained at around 600m for the day.
This was a car split. We dropped a car at at the start of the tourist track and retraced our steps to Dunlewey, turning right at the old hostel and following the way marked route to the foot of the beautifully named Sliabh Bealtaine. We left the car here and headed up a track for about 700m before taking a direct line across bog to the foot of the North West slope, which we ascended keeping to a sheep trail to the right of the a stream.
We continued up the next slope, skirting around some scree and reached a lovely ridge of morraine. We followed it around to the base of the spur, where we picked up some trails through the scree on the lower end of the spur. They became one and continued up through a narrow rocky arrete. The route was fairly clear but it did take some trail finding. The rock was very slippery and a detour around a step ended in a narrow scree fill gully and a nervous moment or two. Rule no 1 on a rocky ridge, don’t divert.
We reached the summit in drizzle and very poor visibility, marked the moment, and headed for the carpark. It is a lovely route but one that require some scrambling and short sections of narrow exposed ridge walking just below the summit, which could be very challenging on a windy day. Some experience on exposed, rocky ridges is necessary before tackling this route. Having done it, I don’t think that I will be doing the tourist route again.

TMC members met in the carpark at Lisleibane and headed in the Hags Glen, crossing the Gaddagh just south of the bridge and headed south to the start of the spur called the Bone. As soon as we gained height it became clear that the wind was too strong to stick to the planned along the spine of the spur.
The route was changed and we went up the side of the spur to a small coum. We contoured across to the spur on the southern side of Cumeenapeasta Lake, on ground that we would’t normally be on, so we did a bit of exploring and identified some interesting routes for future outings. We descended along the stream running from the lake to the Gaddagh and headed to Cronin’s Yard for a cup of tea. Thomas treated us to apple tart.
An interesting thing happened on the way to the Bone. A Kestrel hovered above for about 5 Minutes.

This was a 12k walk in the Magillicuddy Reeks (Map 78 OSI 1:50,000 map) by members of Tralee Mountaineering Club (TMC). Taking part were Nuala Finn, Bairbre Hickey, Bertie Hickey, Andrew Kelliher, and Ciarán Walsh. Leadership was shared.
The forecast was for a cold bright day. Bertie and Bairbre could see snow on the reeks so we opted for one of hidden gems of the Magillicuddy Reeks, the Commeenageargh Gully, which is situated halfway between Skregmore and Beenkeragh .
The walk had many of the features of a Quality Mountain Day. Easy scrambling in the gully and on the Beenkeragh Ridged compensated for a relatively short route over familiar terrain. The snow did not present any difficulty but added a spectacular visual dimension to a walk two days before the official start of Summer in Ireland.
A High pressure area dominated, providing bright skies. Temperatures remained low and there was a light covering of snow on the upper reaches of the Magillicuddy Reeks
THE ROUTE / WALK
We started from Liosleibane carpark, and headed to the foot of Knockbrinnea, picking up a trail that roughly follows the 500m contour. We crossed the Kealnafulla and Kealnamanagh streams before skirting around a spur and reaching the Commeenagearagh valley, at the back of which is the gully.
There is a wet step at the bottom of the gully but this is easily climbed. The gully itself is straightforward, but some sections are loose. We encountered some patches of snow at the top of the gully. We headed Southeast, climbing a rocky spur to the summit of Beenkeragh and crossed the Beenkeragh Ridge.
The snow increased after passing the top of Central Gully and there was a light covering at the summit. The weather was fine and the views from the summit were spectacular. We descended the spur running southeast towards the Devil’s Ladder before turning left for the start of the track leading to the Heavenly Gates.
We went down the Heavenly Gates and out under the Hags Tooth Ridge, more properly known as Stumpa an tSaimh (Stump of the Sorrel). We left the track and crossed the Gaddagh River where it leaves Lough Gouragh and headed back to the Lisleibane along the main track.
This is a long overdue log entry, the first in a serious backlog of entries. But – HEY – keeping up to date is always A problem with log entries! So, Here goes.
The TMC level 3 walk on Sunday April 22 2018 was led by Maeve Higgins. The walk took in a wide arc to the north of Anascaul Lake (Map 70 OSI Discovery Series), taking in Stradbally (798), Beenoskee (826), and Binn an Tuair (592). A total distance of 15.5K.
A sunny day was forecast; a well established to the south west kept low pressure (rain and wind) to the Northwest. It turned out to be a perfect day for mountaineering.
THE ROUTE / WALK
Maeve Higgins led and 11 other members of Tralee Mountaineering Club (TMC) took part (see photo). The walk started at the carpark at Anascaul Lake, crossed the river northwest of the lake and headed up the steep southern slope of An Ré Mhór (Reamore), before heading to a cairn at the summit (500m).
From there we trekked to spot height 346 at the centre of the large plateau above Gleann Tí an Eassaig. Then straight up for 453m to the summit of Stradbally for lunch. On to Beenoskee, where three of us decided to descend.
The remainder (red line on the map) headed for An Com Ban and on to Binn a’ Tuair. They descended to the ford on the Macanabo trail and followed the trail back to the carpark. The other three (green Line) descended the long spur to the col between Machanabo and Anascaul and headed south to a steep gully below An Com Dubh. We joined the trail about 500 metres from the carpark
Both walks walks covered roughly the same distance, 15.5 kilometres over 5hours approx. Total ascent to Beenoskee was 939m and 1,140 in total for the red route, 971 for the green route.
NAVIGATION MADE EASY 2: RECOGNISING FEATURES ON A MAP
The last blog in this series dealt with grid references as an effective and safe way of navigating from point to point. It stressed the importance of being able to read a map, identify potential hazards, and plot a safe route accordingly. This blog looks at features as an essential part of route planning.
The first part –Identifying Features looks at how features are represented on a map. The second part – Navigating using features –looks at we use features to plan a route and navigate “on the run.”
The blog will look at features in and around Loch a’ Duin, an area that is used regularly by members of Tralee Mountaineering Club (TMC) to practice navigation skills.
WHAT DO WE MEAN BY A “FEATURE”?
A feature is a distinctive detail in a landscape that can be easily identified on a map and given a grid reference (plotted). Some features are easy to spot on the the Ordnance Survey Ireland (OSI ) 1:50,000 maps because they are represented by a combination of symbols and colours – a trail (—), a wall (––), a river (––), elevated ground or spot height (•73), a summit (brown circle, spot height, and name where relevant), Special features like archaeological sites (•) are also marked. Some maps (Harvey) have symbols for crags, cliffs, boulders, scree, and other features.
The full list of symbols is given at the bottom of the 1:50,000 map and it is important to be familiar with the key features that are used for navigation in the mountain – tracks and trails, walls, rivers/streams, lakes, spot heights, and summits and so on.
This is the easy bit.
Most features in the mountains are described by contour lines on a map. Contour lines are the continuous lines that represent changes in height in the landscape. Being able to read and interpret contour lines is an essential part of safe navigation.
The section of map above shows contours as they appear on OSI Map 70. The diagram below it shows how contours represent changes in the height and profile of mountains. The third image is a useful representation of the relation between contours and the landscape. Map reading involves using changes in height and profile on the map to identify features in the mountains and vice versa.
This video by Steve Blackhall of the Ordnance Survey office in Great Britain is a good introduction to the contours, just be aware that the maps used in the video are British maps.
NAVIGATING WITH CONTOURS PART 1: IDENTIFYING FEATURES
Navigating with contours involves thinking about the relation between contours and characteristic features in mountain landscapes. There are two aspects to this, knowing where you are and avoiding hazards. The first has to do with being able to read a map and the second has to do with planning and following a safe route (navigating).
Lets look at the first part – using contours to identify features. To begin, how do you know whether you are
The answers are fairly obvious: Just look around you. What if
Take the following scenario. You are heading into to Loch An Duin from Kilmore Cross (Q52294 08919), intending to climb to An Starraicín (Q52769 06407) at a height of 456 metres (see map below). Visibility is less than 20m and you have to navigate by map. You have reached the edge of a lake but the map shows two lakes, one on either side of An Starraicín.
How do you know whether you have reached Loch an Dúin or Loch Chom Calláin?
Loch an Dúin is approached along ground that lies between the the 100m and 120m contours, rising 20 metres over a distance of one kilometre approx. The contour formed by the edge of the lake is given as 116 metres; the height of every lake is indicated by the blue coloured number on the “surface” of the lake. To reach the lake you will climb 1m in height for every 50m in horizontal distance travelled, a gradient of 1:50.
Loch Chom Calláin is approached along ground that rises from 100 metres to 230 metres over a distance of 1.3 kilometres approx. The contour formed by the edge of the lake is given as 231 metres. The key feature here is middle section of the route. The contours between 130 metres and 230 metres are closer and more or less evenly spaced over a distance of 600m approximately. This means that you will be climbing 1 metre in height for every 6 metres in distance travelled, a gradient of 1:6. This is a very different profile to the approach to Loch An Duin.
The question now is this:
Did you approach the lake by travelling along relatively flat ground or by climbing a moderately steep slope?
This scenario demonstrates how you can use information provided by contours to identify features and confirm your location. This is a fundamental part of navigation. Certain features have characteristic contour profiles that make them easy to identify, incorporate into route planning, or use when navigating “on the run.”
Here are some examples:
Here are some standard descriptions of each of the features shown above. All the features are on routes used regularly by members of Tralee Mountaineering Club (TMC).
Summit / Peak
This is the top of the mountain. It is a point on a surface that is higher in elevation than all points immediately adjacent to it. It is usually marked with a brown circle, a spot height, and sometimes, a name – not all spot heights are summits and not all summits have names, Unnamed summits are usually referred to by the number (elevation) given as the spot height.
a continuous elevated crest running for some distance between summits. The sides of the ridge drop away from a narrow top.
Ground that runs down from a hill to lower ground. A spur is an erosional feature that usually forms the side of a valley. Spurs provide access to and escape from the high ground for mountaineers.
An aréte is a narrow rocky spur which separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys.
A vertical, or nearly vertical, rock exposure. Cliffs are a real hazard but can be very useful as a “handrail,” a feature that you can follow, at a safe distance from the edge of course.
The lowest point of a ridge or saddle between two peaks, typically providing a pass from one side of a mountain range to another.
This is the side of the mountain, running from the summit to the foot. Slopes can be convex or concave.
A convex slope is rounded like the outside of an upturned bowl, i.e. it goes from less steep at the top to more steep at the bottom; the space between contours gets narrower as the elevation reduces.
A concave slope is rounded inward like the inside of a bowl, i.e. it goes from more steep at the top to less steep at the bottom; the space between contours gets wider as as the elevation reduces.
a small valley like formation formed by parallel spurs. The low ground between the spurs is sometimes called a draw and is usually associated with drainage or a rivers/stream.
A gully is a long narrow valley with steep sides.
There are two types of features that can be used to navigate in the mountains. The first type is marked on the map using a combination of symbols, colours, and numbers and includes tracks/trails, rivers/streams, spot heights etc. The second type consist of formations that are characteristic to mountain landscapes and include summits, ridges, spurs, cols and so on. These features are described by changes in height and profile (shape) that are represented on the map by contour lines.
