The Simian Sounds zone is one of my favorite zones in the Narrows. There is clean granite for the areas that combines sport moves above bolts with bomber trade placements. The approach is a little complex and steep so take your time. A few newly installed fixed lines will help guide you. The Simian Sounds zones has many hanging belays and tight belay stances so I recommended a team of two.
Proto Language 5.9
Check out the new lower pitch called Proto Language that will take you directly to the Spunk Monkey belay. (You can also exit the pitch early to the right and get to the Mechanical Doll Fight belay.) Proto Language starts on a slab for a few bolts before steepening into a left facing corners with several trad placements. There is a final cruxy bolted headwall in white rock before the Spunk Monkey belay. The pitch is brand new so expect to have to blow off a few holds and as always wear a helmet. The following picture shows Proto Language and Spunk Monkey. There are several other routes in the picture not depicted. Check out page 250 in the Wester Sloper for the full details.
Spunk Monkey 5.10
Ascend a fantastic right facing corner with bolts.
