The minor road, to the south of Binnion, has had some road works carried out on it recently. The upshot being, it is possible to park a car on the verge and leave the road clear, at around C376476 A.

From here walk up hill to the track beside the cottage at C375479 B, mentioned by eflanaga, and follow this to a fork, either one brings you out onto the open hillside. And if you bring a carrot, the friendly horse in the field, at the fork, would appreciated! From here follow the track up hill (faint if you have taken the right fork) into the gap, where the track is clear and easy to follow. Just as the track swings left there is a minor ring contour, on your right, topped by a cairn at C374491 C, which is worth climbing up to for the view of Pollan Bay (see attached photo).

Pass a fork and shortly after, leave the track and climb to the summit, again with expansive views over Tullagh Bay and Rockstown Harbour to Dunaff Hill. Which we had climbed earlier in the day. Linkback: https://mountainviews.ie/summit/1003/comment/5883/

I climbed Binnion on Fri 5 August after a short walk up and down nearby Coolcross Hill. I followed eflanaga's excellent route, parking just off road at C3758447958 D. As far as a description of the walk is concerned I could not add significantly to what has already been said other than to commend it to anyone wishing to climb this hill. On setting out the low escarpment directly ahead does not prepare you for the sheer delight to be found in walking this winding route mostly on a good and well defined hill track with frequent opportunities to take in an ever changing panorama. Once at the summit area I was surprised to find that the fine cylindrical cairn (still adorned with its metal post!) is not, in my opinion, actually standing on the highest point. This is in fact reserved for a lesser cairn of stones some 30/40 metres to the NE (see photo). Although you could be up and down Binnion in something under 1 hour 30 minutes this is not a hill for a quick ascent, this is a hill to be enjoyed, so allow time just to potter about. I spent just under two hours on the hill with many stops and diversions to appreciate the beautiful scenery all around me. A walk of some 5.5km.

In the townland of Clonmany Co Donegal 1 mile outside Ballyliffin at 55.280791, -7.402445 park your car at the Y junction & get your gear on.
The dirt track leading off the road is about 1Km long and a great warm up, it leads to an old town called Mullagh (no one lives their). Once at Mullagh town go through the two pillars and enter the hill, follow the markers leading up to the right and then at the top of the hill 100 meters turn left that will take you to the Christian Mass rock while following the markers at the mass rock you views will be of Pollan beach, The Isle of Doagh it’s a sheltered area.
Turn back on yourself along the markers for about 100 meters, you should now be facing the main hill cross the small bog onto the heather and follow the markers to the old cart track that winds its way up the hill until a view of Malin Hd and Glashedy Island comes into view. This is another great spot for a reflection.
Head round to the left following the track and markers about 1 mile you will come to a Y take the right track and head for the summit, it has many good views westward to Fanad and East to Malin Head and on a good day the Scottish islands you are encouraged by locals to add stones to the cairns on top of the hill.
Head back to the Y and turn right to complete your loop follow the markers down the hill at the bottom the marker will point sharp left follow the markers along the old wall to arrive back at the bottom of the old cart track then join the trail to take you back to the start from where you came.
This is a more rugged and historical trail then the other routes as it takes in the Mass rock, Mullagh town & the stone walls on the hill. Linkback: https://mountainviews.ie/summit/1003/comment/20862/

Start out from one of the most beautiful beaches in the county at Tullagh Bay (carpark at 348485 E) - an almost perfect horse shoe bay with golden sands and a pebble border. The cool summer weather meant only a handful of people were walking the sands, able to see the wind lifting spray off the tops of the rolling breakers squeezing into the bay. The tide was out and the beach was in its full pristine glory.

A river flows in at the eastern end of the beach and cuts off a smaller area of beach and Binnion itself. This cuts a deep channel through the sand and a quick trip into the dunes was needed to strip to my boxers to wade the river. I was able to dry and reclothe on rocks at the others side. Two dead seals lay here as fare for gulls and other birds. Walk to the end of the beach and then up into the dunes, passing an army of black slugs, snails and caterpillars, to reach a storm beach on the other side of Sull Point (364492 F). Views here reach to Malin Head and sounds come from the waves moving thousands of pebbles up and down the beach.

Climb on steep grassy slopes, getting an even better perspective on the power of the sea on the storm beaches below. Skirt areas of large overgrown block scree to reach an a level area at 250ft with a large drystone wall. I got a good feeling for the dramatic rise of Dunaff Head from the sea to the W as big showers passed out to sea. The climb is cracking and varied - clearing paths through deep ferns, stepping over areas of scree and heather and some light scrambling - there is a rough path to follow (mostly).

Reach a wall and the rocky top with new growth heather (fire?). A lovely cairn about 5ft high with a makeshift flagpole and weatherworn material, including a black bra! Top reached in just over an hour and 2.5 miles and is well worth spending some time exploring. In the fading light of dusk bright lights of settlement peppered the base of the hills of Inishowen.

I followed one of the large stone walls down SW as i didn't fancy retracing my ascent in the dark. The river below had swollen to the size of a lough with the tide now in with the lights of caravan parks as a backdrop. The wall descends steeply and more high ferns need to be negotiated. I followed the banks of the swollen river back to the storm beach at the foot of Binnion where i camped for the night. A windy one and there seemed to be a shower passing everytime i woke.
Next morning the tide was still in so was no chance of wading back across the river - i followed its banks to cross a small concrete bridge and reach a road (366479 G) which i had to follow back towards Clonmany before turning R and following this road to a more substancial bridge which brought the beach. A half hour diversion but pleasant walking with nice views across to Ragtin More. A great little adventure - not far in distance from civilisation but a million miles away in my mind!

I parked my car at the binnion caravan park. Then set of following the path towards the beach, as you walk along the beach you will come to a horse shoe bay surrounded by steep sand dunes. I climbed the sand dunes and headed to the back of the mountain ( north side ) along the secluded beach of portlackin, a hidden gem. Then i started my climb of binnion hill, steep and challenging. Once your about half way up you are met of old time sheep walls which have gaps at some points. A heather filled hill until your close to the top were you are met with more rocky ground . Once at the top you will see a beautiful cairn and the views are amazing. North east Glashedy rock, East slieve snatch, South Raghtin more starring straight at you and to the west Dunaff and leenan. A 250m hill with a punch,Well worth the walk!! Linkback: https://mountainviews.ie/summit/1003/comment/3853/
