moderateYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarGray Star(55)
Length: 2.6 mi • Est. 2 h 10 m
A challenging trail, but completely manageable. There is a small carpark at the bottom of the track. This route takes you through many different styles of Irish terrain and allows amazing views of both the vast valley's and blue ocean. There are no trail markers and no clearly defined paths at the beginning of the trail. Just line yourself up with the mountain peak and make your own way up. For the first 30 minutes or so, you're stepping around through marshes and trying not sink your boot into muck as Mt. Errigal stands apart above the abundant peat bogs of Donegal. The descent is easy and fast. If you haven't done quite enough then bearing left and over the bealach to the slopes of Mackoght will probably take you away from the others on the hillside and offers a different perspective. A good bit of scrambling is involved but the views from the top are well worth it as the ascent is short.Show more

Starting and finishing point is Tra Na Rosann Hostel. From a hostel you head down to Tra Na Rosann beach. Follow up to Rossess Point (in places it is a boggy area!) From Rosses Point over looking Tra Na Rosann beach and Boyeeghter  Bay, climb up to a hill just above a hostel (don't know if it has any name, on a map it's marked as point 163 and it is a highest hill in Melmore Head). Follow a fence on my left, Tra Na Rosann beach and Tranarossan Bay on my right. From a top of the hill are magnificent panorama views of Fanad Head, Mulroy Bay, Rosguill Peninsula, Horn Head and Tory Island (distance).  From this hill above a hostel, make your way down and up again on top of Gortnalughoge (125 m) where a WW2 concrete look out tower was built. There is a lake in a L shaped - Lough Melmore. On left from this lake is a big sign "78 EIRE". It was a sign for aircrew to let them know they are entering an Irish neutral airspace ground. From here take your time and extreme care to make your way down to Boyeeghter Strand. Alternatively you can contour around and make you way down to a valley beside Lough Melmore. From here follow shores of Rinawany Point, Shanlough Point  untill you get to Melmore Hill in Melmore Bay, yet again you can see unspoiled crystal, clean beaches. Pass by Lough Beg and head from Melmore Hill to Melmore Head. On top of Melmore Head you wonderfull panorama views overlooking Tranafaghaboy Bay, a lighthouse on Fanad Head. There are ruins of an old Napoleonic watch tower built in 1800s. From here make you way back through holiday caravans park back to a hostel (main road)  OS Map No. 2 Show more

Length: 10.1 mi • Est. 5 h 19 m
Enter the heart of the Bluestacks from Lough Eske to Letterfad via the Eglish valley. You'll have enjoyed two good days on the Bluestack Way at this stage, but what comes next is possibly the best part of it. The sight of the pristine and perfectly manicured Tymeen football pitch, the sacred serenity of Disert, the hulking presence of Carnaween, the agony of climbing up Lugnabrogue, the ecstasy of getting to the top and admiring the best view in Ireland, the calmness of Doobin, the surreal sight of a sofa just when you want one and the joy of seeing Glenties are yours to behold - this is one special section. Starting off at Lough Eske Castle by the banks of Lough Eske and at the base of the magnificent Bluestack mountains, the second part of The Bluestack Way App meanders by the shore before rising to give you a panoramic view of the area right across to county Tyrone before entering the valley of Eglish, passing Owenboy and getting us as far as Letterfad bog before settling for the night at The Bluestack Centre. Some of the treats you can expect to find on today's walk are the (possible) sighting of golden eagles, Californian redwoods, red deer, blue hare and every sort of flora from marsh marigolds to cuckoo flowers, meadowsweet to umbellifers. You're in a place of immense beauty and fresh air where lichen grows freely as it does where air is truly fresh and where everyone from Fionn McCumhail to friars, gentry to bandits have visited and savoured.

Length: 2.7 mi • Est. 2 h 7 m
NOTE: most hikers suggest not doing this as a loop and instead descend the same way you go up. The descending loop is treacherous especially in wet conditions. You will need good boots with excellent lateral support if you take the descending loop. Muckish Mountain 666 m (2,185 feet) Muckish means in Irish "the pig's back". It is the third highest peak in the Derryveagh Mountains and 163rd highest in Ireland. Mount Muckish is also second highest of the mountain chain called the "Seven Sisters" by locals (other mountains includes Crocknalaragagh, Aghla Beg, Ardloughnabrackbaddy, Aghla More, Mackoght and of course Errigal). There are two routes to climb Muckish. This is a tougher route called "Miners Track"  which is the path used by workers to reach a former quarry on the flanks of Muckish. There is also another route up to the mountain - via Muckish Gap, this one is easier and most popular way. From R251 take turn for Falcarragh (An Fal Carrach). This road will take you to yet mentioned Muckish Gap. How to get there: From N56 travelling from Letterkenny, about 3 km after Creeslough village (just before Ards Forest Park on right) turn right to a road signposted for Derryharriff. This road is hilly and narrow, so drive with care. On you left you can see a dismantled railway from Letterkenny to Burtonport (closed down in 1940s). Keep driving straight. On right you pass Muckish Quarry, Muckish Mountain in distance ahead of you, Muckish Ministry on your left. Keep driving up until you reach a cattle gate, drive through it, don't turn right. You can see now clearly a dismantled railway which is nowadays a walking trail.  Keep driving up, crossing an old dismantled railway (a small car park on right). There's another small car park behind some 1.5 km up, some 200 m where a road ends. You can still drive up just below a Miners Path, there is a place to park your car as well but road is steep and rocky.   One the way up via Miners Path, you come across a former quarry, some equipment left behind as a forever reminder of old mining times. Till this point a walk is quite adventurous, climb with caution!  After you reach a former quarry area, the walk on top of Muckish is just few hundreds yards away. Firstly you come to a cairn, there are fantastic views along the route of the famous Glover Highland Walk taking in the Aghlas, Makoght and Errigal. From the opposite end, there are contrasting views along the northern coast of Donegal taking in Rosguill in the foreground and stretching to Fanad as far as Inishowen dominated by Slieve Snaght and it’s surrounding hills. The top of Muckish Mountain is full of rocks. There is a big cross on one end of the hill with magnificent panorama views. You can walk down same way you climbed up.Show more

Note: Users have reported that there are lots of hidden undercover waterways and the trail is very boggy, so watch your step. When starting out from Billy's pen look for the running water stream. Follow to the tree and head off at 2 o clock direction and you will come to a gate, always close the gate after you. Good waterproof boots highly recommended.Show more
