Kalymnos – Olympic Wall (Space Terrace) · Kalymnos & Telendos · Greece
Bail with caveatsBolting confidence: high
A mountain-style outing high above Masouri, with a delicate traversing 6a on P4 and a lovely final corner. Most pitches feel easy for their grade, but the route is loose in places, so wear a helmet.
The route
A recent seven-pitch route high above Masouri in the Olympic Wall area, starting from the Space Terrace just right of the fixed rope that gives access to it. It has a mountain feel: a long approach, ledges between pitches, a line that moves right, then left, then right again, and a walk-off down a gully. The climbing is mostly easy for the grade, with a delicate leftward traverse on pitch 4 and a good final corner as the two 6a pitches. Bolting is very generous, but the rock is loose in places.
The climbing
| Pitch | Grade | Length | Notes |
|---|---|---|---|
| P1 | 5b | 25 m | Up to a ledge, then move about 10 m right along it. |
| P2 | 5b+ | 20 m | Straight up over a few steps and a small slab. |
| P3 | 5c+ | 20 m | A little more technical. A UKC comment describes it as trending up and left and only about 15 m. |
| P4 | 6a | 20 m | Traverse left. Delicate and very good. |
| P5 | 5+ | 30 m | Back right. One harder move, then easy. The camptocamp grade is garbled ('5|+'); it is read here as 5c+. |
| P6 | 5b | 30 m | Right again to a ledge. |
| P7 | 6a | 25 m | The final corner, very good. There are chains at the top; a 2025 UKC comment suggests continuing past them to belay on single bolts in a safer position. |
Getting there
Base: Masouri. Walk or ride 1.5 km along the road towards Kastelli, then go up to the isolated house under the electricity pylons and follow the stone wall beside it to the scooter parking used for Odyssey. An hourly bus runs between Pothia and Kastelli.
From the scooter parking take the blue-marked path up to Odyssey. Level with Odyssey turn right and contour, cross the ravine, and at four large cairns (the Odyssey / Iliada / Olympic Wall junction) go uphill following red marks, cairns and big green dots. Traversing left brings you to the wall and a fixed rope. The route starts just right of that fixed rope; a 2024 UKC comment puts the first bolts 1 m right of it. About 45 min from Masouri, 30 min from the scooter parking.

Getting down
Walk off: go right from the top, then down the gully (cairns and a fixed rope) to return to the Space Terrace and the start. A 2024 party called it quick. Abseiling the route is not recommended because of loose stones.
Retreat
Bail with caveats
You can abseil off, but camptocamp advises against it because of loose stones. The line also moves right, then left, then right again, so abseils will not follow the pitches neatly. The intended way off is to finish and walk down the gully.

Safety
Sun and weather
The route itself is listed as south-west facing and was in shade until about 11:30 in early October 2024, then very hot in the sun. The main Olympic Wall nearby is described differently (sun from about 14:30, somewhat exposed to north-west wind), so do not rely on the wall's shade times for this route. Quiet because of the longer walk. Spring and autumn.

Greece · Kalymnos & Telendos
The first route on the wall (Odermatt and Keller, 2008), climbing a long, exposed line on sharp, grippy rock right of the huge roof. The lower pitches are easy for the grade. The two 6a cruxes are a short odd corner over a small roof and a traverse high up, and they come with big exposure. Pitches are short, so you can link them with long draws.
6a11 pitches250 m
Greece · Kalymnos & Telendos
A sustained, varied line on sculpted limestone. It starts with an easy slab and builds to slightly overhanging jugs with huge exposure on the top pitch. Mountain Project and camptocamp grade the crux 6a+ (Rockfax says 6a). With a 70 m rope you can link several pairs of pitches.
6a9 pitches265 m
Greece · Kalymnos & Telendos
Kalymnos's best-known introduction to multi-pitch: a series of steps and slabs, always with plenty of holds, finishing on top of the Grande Grotta. The upper pitches feel very exposed. Real pitch lengths are shorter than the guidebook says (20–25 m).

Committing
Greece · Kalymnos & Telendos
Thin moves over small bulges, stemming and big jugs on 'cauliflower' limestone. The crux is P6, which ends at a hanging belay. Mountain Project gives the pitches in YDS only (5.8–5.10b), so French pitch grades are not listed; the overall grade is 5.10b (6a+), and some listings give 6b. You can link P3–P4 and P5–P6.

Spain · Riglos & Agüero (Mallos)
This is the gentlest way to sample Riglos. Polished pockets and two bulging 'panzas' lead to a 6a crux that can be pulled through on the bolts (A0). The upper spur is easy, and the Pisón towers loom close by.

Italy · Aosta Valley
A pretty plaisir route on edgy, quartz-studded granite slabs beneath the Mont Blanc massif. The crux is a short bulge and steep juggy wall on P4. Camptocamp rates it 'great'.
6a7 pitches180 m
Italy · Monte Argentario
A long arête that seems to drop straight into the sea: a sustained 6a first pitch, then corners, slabs and short walls at 5a to 5b+ separated by easy scrambling, with an exposed traverse out on the open face near the top. The 6a can be aided.

Croatia · Omiš
Omiš's signature moderate: long, slabby pitches on knobbly grey limestone with big views over the Cetina mouth and the Adriatic. The crux is a short crack on the final pitch.
