Very beautiful pink granite stone built trig. Met Neil Fraser from Lerwick who'd intimately documented and walked the precise N/S watershed.

Stone built pillar (pink granite) - some top screed missing - in mist, 100m or so visibility - very atmospheric.

From Collafirth Hill, plenty of parking near the masts. Easy, gently sloping ground. Across to Mid Field first. Lovely stone-built pillar using local red stone sited in a shelter cairn. Top has some superficial damage to the screed; original centre cap retained, raised lettering; rear sight hole open. Superb views over much of Shetland. Geocache at rear of pillar.

Set off from Collafirth hill in the mist and rain. Forecast for the day was supposed to be dry and cloudy! Navigated my way to the summit with the rain going off and some clear spells, but still thick at the top as I could barely see the burial chamber from the trig.

Levelled for height in 1961. Last maintained by the OS in May 1980. SITE VISIT: Overall approach from east. Parked at top of road on Collafirth Hill by masts at HU334835. This road can be driven by car and seems to be open to public, information board at top. Route is WNW via Mid Field, west onto bealach and beeline southwest up Ronas Hill to its summit. Highest point on the Shetland Islands. Rocky plateau but easy underfoot. Stone built pillar within wind shelter in fair condition. Spider has replacement OS centre cap with raised small narrow letters. Flush bracket faces ENE, ~59°. Vented through SW sight hole. Full 360° panoramic view includes Foula.

Metal cap, small raised letters. Top slightly damaged. Built of local granite, inside shelter cairn. Wet and windy day but last of trip and my final Shetland trig pillar. Burial chamber is impressive, and a handy place to shelter while writing log! 65m SE of trig.

I parked at the masts on Collafirth Hill and set out walking at about 12:30 to the north of Roga Field and Mid Field to avoid too much of an ascent before Ronas Hill itself. The landscape - if ignoring the greenery - could easily be Martian! Red stones and boulders abound - and are very handy for crossing the odd wet patch. Although I had started in bright sun, as I reached the top the cloud level dropped and I was unable to see very much for a few minutes. The pillar is stone-built from local red stone; FB faces ENE; WSW sighthole open, all others appear plugged; metal cap with unusual-looking thick raised letters. I signed the guest book and ate a sausage roll from my supplies before the cloud lifted and I could admire the view of almost the entire Shetland archipelago - all the way from Muckle Flugga (29 miles) and Saxa Vord in the north-east, round to Foula (35 miles) in the south-west, to Fair Isle (69 miles) and Fitful Head (43 miles) in the south. This is a good place to collect Intersected Stations too: Esha Ness Lighthouse (TP9643), Ungam Beacon (TP8865), North Unst Lighthouse (TP9642) and the replacement for Ness of Sound Lighthouse (TP9647) are all visible from here, and others may well be too. Very impressive indeed and well worth the 2.2 mile walk. However after spending about 35 minutes at the top I carried on further to see if I could find the Valla Kames bolt (TP10485).

Arrived 3 minutes to midnight. A local man told me he took the chance to hike here tonight as it could be the last time he manages it due to arthritis. He pointed out and named all the far off lights, he also said this was the best mid summer for about 20+ years. A story that I was to hear numerous times over the following weeks. I signed the visitor book, took some photos then carried on over the hill to the cairn at Abram's Ward then back around the hill to Collafirth hill where my bike was parked. No torch was needed until I was taking a compass bearing at the cairn to get me back around the hill to the masts. What a way to spend Mid Summer WOW

Very cold, very windy, only top of trig pillar visible above drifted snow so no condition or confirmation of flush bracket nor book in metal box available, see photos, but amazing weather features as sun, just one day from its winter zenith, shone through curtains of hail showers. A special day and well worth the effort.

reason why there was no flush bracket confirmation
Not a usual position to check trig point details.

An unusual trig point, having been skillfully clad with local red granite. It is enclosed by a wall shelter and there is a visitor’s book in a wooden box. 40m S of the top, and at the same altitude is a chambered cairn.

Park at Collafirth Hill HU335835. An easy moorland walk of about an hour to the top of Ronas Hill.Could be difficult to find in hill fog as there are few features.
