Follow the approach to Ha Fa Shan until the shelter at the top of the hill. From here turn left and follow a dirt path around a small knoll. Continue along a concreted path up the gently sloping hillside. Approximately 40m past the remains of an old shelter (steel framework remaining) break right along a vague dirt track up a small hill to join the ridge above. Follow the path up the ridge a short way until several other vague dirt paths join it. Follow the right most of these paths up and over the next ridge line towards a grazed piece of hillside containing several grave sites. From beneath the graves either:

a) follow a dirt path down the hillside towards a densely vegetated stream valley. Find a path through the vegetation to the other side of the stream (hint: lower down is better) and then continue back up the hill to the Supersonic Boulder / Lonr Ranger Boulder, or:

b) head up the hill above directly to the Graveyard Boulders and, from approximately twenty metres below these, contour rightwards around the hill to the Trackside Boulders.

(1) V1 ** Spike. Step off the large spike and reach into the hanging crack. Follow this to the top.

(2) V5 * Super Furry Animals. The steep scooped wall, exiting slightly left of the vertical seam

(3) V2 Quickstep. Tricky moves up the lefthand side of the boulder.

(4) V1 Bear Necessities. The thin wall on the left end of the tablet using the aretes on either side.

(5) V4 *** Tomb Raider. The lefthand arete of the main wall, on its right hand side.


(6) V1 Epitaph. The arete and crack on the right hand side of the tablet. The boulder on the right of the tablet is out of bounds.

(1) V0 – 4c Slanting Crack. The diagonal crack up the lefthand side of the slab.

(2) V1 ** Don’t Look Down. The centre of the slab, right of the slanting crack. It may be low in the grade but its definately scarey.

(3) V2 *** Supersonic. A fantastic problem up the steep side of the overhanging arete. From the good jug reach up to holds in the crack on the arete. Continue past the end of the crack and, using poor holds higher up (where the arete flatten out slightly) rock over onto the slab. Amble up the slabby arete above to the top. The sit down start from slopers low down is V3.


(4) V4 ** The Lip Trip (sds). Start as for Supersonic but instead of rocking onto the slab continue rightwards to the highest point of the overhanging wall. Finish up the crack above as for Crouching Tiger.

(5) V6 *** Crouching Tiger. Start with both hands in the fragile looking flake in the middle of the overhanging wall. Reach up to jam the crack in the lip and then go for the flat ledge left of this. Mantle the ledge at the lip using the crack to the right. A sitting start to this problem from the good crimp low down looks just about within the realms of reality!

(6) V1 ** Cocaine. The overhanging crack, rocking round onto the slab to finish.

(7) VB – 4c Descent Arete. The arete and wall at the back of the boulder. As the name suggests, this is also the easiest way down.

(8) V0 – 5a Scooped Arete. The arete on the righthand side of the scooped face of the boulder at the rear of Supersonic Boulder.

(9) VB – 4c Scooped Slab. The centre of the short concave slab.

(1) VB – 4c ** Scooped Wall. The scooped wall on the back face of the boulder.

(2) VB – 4c ** Into The Groove. The groove line just left of the big split.

(3) V0 – 5a Blunt Rib Wall. Somewhat of an eliminate, squeezed in between the adjacent two lines. The narrow wall between the groove and the rib.

(4) V0 – 5a ** Blunt Rib. The blunt rib on the lefthand side of the back face of the boulder.

(5) VB – 4c* Bloodsport. The crack just down the hill from Blunt Rib.

(6) V0 – 5a ** Scenic Wall. The wall just left of the crack.

(1) V2 ** Snap, Cackle and Pop. The thin crack on the righthand side of the face.

(2) V7 ** Angels Wall. Start at the short vertical crack and, using pebbles and pockets to the left, climb the middle of the gently overhanging wall.

(3) V6 *** High Silver. Pockets and crimps up the wall right of the arete, avoiding holds on the arete itself.

(3a) V8 *** Low Silver (sds). The sit start to High Silver is both fierce and excellent. Start directly beneath the arete and throw to pockets on this before joining, and finishing up, High Silver.

(4) V3 *** Phantom Pregnancy. A hard start is followed by a scarey finish. The righthand side of the arete.

(4a) V6*** Abortion (sds). The sit start to Phantom Pregnancy, using the same holds as Low Silver.

(5) V3 ** Ping Pong. The slabby wall just left of the arete.

(6) V1 *** Retribution Rib. Good but scarey! The rib just left of the big split.

(7) V1 * Hong Kong Phoey. The steep lefthand arete, on its righthand side.

(8) V3 ** Impending Doom. Straight up the centre of the blank looking face via an assortment of small crimps and sidepulls.


(9) V2 *** Pockets of Resistance. The steep wall on small pockets and pebbles is a contender for the best problem on the boulder. A classic.

(10) VB – 4b * Ramble On. Amble up the righthand arete of the wall, starting from the nearby boulder.

(1) VB – 4a * Diamond Slab. The centre of the gentle slab.

(2) V1 * Elemental (sds). The overhanging side of the slabs left arete.

(3) V0 – 4c * High Rise. The steep, intimidating arete, on its left side.

(4) V3 * Russian Roulette. From the right side of the wall follow a left tranding line, past a good undercut (beware – this is coming loose) to the top.

(5) V4 ** Mass Destruction (sds). The short overhanging arete provides fun moves low down and a somewhat challenging finish.

(6) VB – 4b * Zig-Zag. Follow the zig-zagging cracks up the short wall.

(7) VB – 4a. The lefthand arete.

Screenshot 2019-09-14 at 11.34.04 AM

(1) V1 * The right arete of the wall.

(2) V4 ** Diamond Eye. Step off the slab to reach a good crimp with the right and poor left hand hold. Finish directly above these.

(3) V6 ** Bamboo (low start). The centre of the gently overhanging wall yields via rough crimps and slopers.

(3a) V9 ** Bamboo (sds). As above but starting even lower down on worse holds and making a couple of desperate moves to get your butt off the floor and then move left to join the original line.

(4) V3 ** Squeeze (sds). The short overhanging corner.

(5) V2 * From good crimps, rock up to the gaping crack and finish up this.

(6) V4 ** Slap Happy. From a good sidepull and crimp, pull through the bulge and finish direct up the wall above.

(7) V3 * Jacobs Ladder (sds). Start sat in the low groove. Reach up and right to good holds in the right trending seam. Follow this till it peters out then finish direct.

(8) V3 * (sds). Start sat in the low groove. Reach up and right to good holds at the start of the right trending seam. Finish direct above these.

(9) VB – 4b. Pad up the slabby left hand end of the wall.

Screenshot 2019-09-14 at 11.42.09 AM

(1) V1 * There is no Spoon (sds). Start sat on the boulder and follow good holds up the arete to the top of the triangular face.

(2) V4 ** The Matrix (sds). Start matched on the low ledge on the right side of the face. Make technical moves left to the large ledge in the middle of the face before cranking directly to the top on small holds. A stand start from the jug in the middle of the problem can also be made at a reduced grade of V3.


(3) V2 ** Reloaded (sds). Sit start on the boulder at the left end of the face. Follow the arete rightwards until you reach the top of the triangular face, slightly trickier than it sounds due to the lack of footholds.

(1) V1 Under the Bridge. Climb the centre of the small slabby face.

(2) V0 ** Over the Hill. Follow the line of flaky jugs up the slightly overhanging arete.

(3) V6 *** The Portal (sds). From a sit start, follow crimps and slopers up the arete until dynamic moves lead to ‘the jug of justice’. From here continue up the tenuous and high arete above.

(1) VB – 4c * Lowball. Follow the crack to is end and then continue up the wall, trending slightly left to a large pocket. Finish directly above this.

(2) V0 – 5a *** Highball. An absolute gem of a problem, all be it a little on the scarey side. Start up the crack but quickly step right onto large pebbles. Continue up the wall on these, with some trepidation, to its top. Superb!

(3) V0 – 5a ** Lobshot. The right arete, staying on its lefthand side throughout.

Screenshot 2019-09-14 at 11.50.27 AM

(4) V0 – 5a * Smash. The righthand side of the arete.

(5) V0 – 5a ** Orange Tree Wall. The centre of the wall following an orange streak via a series of small ledges. Finish just left of the small sappling.

(6) VB – 4c * Green Crack. The crack at the right hand side of the wall.

(7) VB – 4c End Wall. The narrow wall on the opposite side of the boulder to the highball face
