Entering the body-sized tube, wriggle through for a few metres. It is easier to drag large tacklesacks. The passage soon widens, stay on the L wall, and quickly reaches a p4 (RIG11 - see rigging guide). This drops to a large ledge with a slot down. Keep on rope to protect the walk along the ledge then up a muddy slope to reach the ledge at the top of Mongol Rally (~p197, RIG12 - see rigging guide; named after George and Luke saw cars on their ferry out to Expo that were heading out to do the Mongol Rally).
-The upper part of Mongol Rally feels surprisingly friendly as it descends via numerous rebelays and 3 large ledges then 2 hanging rebelays to a rebelay at PT07. This is at an obvious, large window that leads to an extensive, largely horizontal level called Pitstop. PT07 is around 130m below the Mongol Rally pitch head and Pitstop is described in a separate section below.
+The upper part of Mongol Rally feels surprisingly friendly as it descends via numerous rebelays and 3 large ledges then 2 hanging rebelays to a rebelay at PT07. This requires a swing in to gain an obvious, large window that leads to an extensive, mostly horizontal level called Pitstop. PT07 is around 130m below the Mongol Rally pitch head and around 60m above the bottom of the pitch. Pitstop is described in a separate section below.
Below Pitstop, continue to descend around 50m further, past 2 rebelays, to a large ledge. From this ledge R leads W to a c3 down. At the base of the c3, R goes N to a wet pitch (with no QMs???) whilst L continues W into Floodland over fine mud banks in wide passage to a steeply descending mud slope down that needs protection (RIG12-01 - see rigging guide). Rigging from the R wall leads to an ongoing QMA maybe - this needs checking. A final short drop to the L (to the E) from the large ledge arrives at a huge, bouldery chamber. This is the bottom of Mongol Rally and the start of Grand Prix.
The Pitstop area begins at PT07, at a large ledge which you can swing into from the main Mongol Rally pitch. At this ledge, straight ahead, to the E, soon closes down. A traverse (RIG12-02 - see rigging guide) along the N wall leads to a large and obvious horizontal passage on the far side of the main Mongol Rally pitch, called Turnback Time. This goes up a c4 then bends left (ahead becomes too tight) and ends at two QMB 2018 undescended pits that are nearly above large, lower passages so they probably just drop in to them.

-The main way on from PT07 is the short, stooping passage to the S that soon opens up. Continuing ahead leads immediately to some deep, undescended pits, QMA 2018 and QMB 2018, that probably connect down to the large chamber at the base of Mongol Rally. Instead take the walking passage on the L. This ramps down steeply, zig zagging until it pops out at an obvious, important T-junction at PT20 with a significant stream entering from above. This is a good source of drinking water. At thisPT20 T-junction, L enters Southern Pitstop and R goes to Northern Pitstop.
+The main way on from PT07 is the short, stooping passage to the right (S) that soon opens up. Continuing ahead leads immediately to some deep, undescended pits, QMA 2018 and QMB 2018, that probably connect down to the large chamber at the base of Mongol Rally. Ignoring these, instead take the walking passage on the L. This ramps down steeply, zig zagging until it pops out at an obvious, important T-junction at PT20 with a significant stream entering from above. This is a good source of drinking water. At this PT20 T-junction, L enters Southern Pitstop and R goes to Northern Pitstop.
Southern Pitstop begins as wide, horizontal walking passage then, after a pool, it starts to slope steeply down. It reaches an obvious junction. Here, L slopes up a muddy ramp with hundreds of bat bones - care - this should have a path marked with conservation tape. This passage ends at a pitch with the sound of water (QM2018 XC) and a rift continuing above. This rift may just lead to the same pitch, QM2018 XB. R at the junction continues down to the Safe and Comfortable area. The passage initially descends steeply then enters a complex, open area with multiple interconnected streamways.
+Southern Pitstop begins as wide, horizontal, walking passage then, after a pool, it starts to slope steeply down. In 2024 a camp was set up on the left. It was muddy but reasonably comfortable for 4 people or 5 at a squash or with hammocks. The walking passage reaches an obvious junction. Here, L slopes up a muddy ramp with hundreds of bat bones - care - this should have a path marked with conservation tape. This passage ends at a pitch with the sound of water (QM2018 XC) and a rift continuing above. This rift may just lead to the same pitch, QM2018 XB. R at the junction continues down to the Safe and Comfortable area. The passage initially descends steeply then enters a complex, open area with multiple interconnected streamways.
At this complex area the first R leads up to an aven then goes R and descends a rift. This ends at a small pitch requiring a p8 down then a p6 up to a sloped area above the rift Covid Corner , (RIG12-03; is there a rigging guide?).
At Covid Corner the easiest way on is to the right where a small recessed area has a tricky and unobvious 4m climb up. Here there is a junction right leads to a passage ending in an undropped p7. Left follows sloping mud banks before the passage turns sharply right and eventually reaching Tampon Turnaround . This is a complex chamber with an interconnected higher and lower section. To the left of the lower section is a short wide crawl downwards which ends in a perpandicular passage. To the left is a QMB crawl. The right passage becomes walking hight and continues, joining first a dry rift then a wet rift which emerges from the left wall (QMB). The passage eventually leads to a junction where both routes on quickly become impassable.
