Neptune

Neptune is a popular linkup on the Venus wall, so popular that the routes that comprise its start and finish rarely get done. Start on the far left side of the wall and climb the first two bolts of Mercury (12d). Then, cut right and climb two bolts on Venus. Cut right again and finish on Shame on a Chippa (13c).

Endurance is the name of the game, as the crimps just keep coming. The similarities to Venus are striking, as Neptune has a hard start that leads to a sustained middle. Finally, a low percentage, redpoint crux awaits at the top. If you've ticked Venus and are looking for more of the same, then Neptune's the route for you.

Bolts. It's tough to clean because of its traversing nature.
