Atlantis is a nice little area near the southern end of Lost Horse. It's a short wall that sits in a narrow canyon that's pretty well sealed off from the West, so you have to loop around and come in from the east. This means that it doesn't get much in the way of a breeze, so it can be pretty sweltering on a hot day, but it's nice when the weather's a bit cooler.

Atlantis is often overrun with classes and large groups of TRs, due to the easy walk off (down the gully on the far side of the formation from the climbs). TRs are easy to set along the entire length of the formation, and the 20-30 short but steep climbs run from 5.5 to 5.9 and up. None of the routes stand out especially, but it's another nice JT spot that's good for taking it easy or for pushing your grade on TR.

Due to the nature of the wall it has been split into two -

Atlantis Wall - Left
Atlantis Wall - Right

Getting There

Head south on the Lost Horse Road -- as you near the gate (where you can't drive any further) there are a few dirt parking areas. The further down the road you can park, the shorter approach.

Head east from the road -- from here, pretty much all of the main Lost Horse formations will be on your left. After a few hundred yards, you should come to a low spot in the rocks on your immediate left. Here, turn left and head back into the rocks. Almost immediately, you'll pass the Atlantis descent gully, and then a low scramble over the toe of the Atlantis buttress. Once you're into the next, wide gully, turn left again. A little more scrambling, and Atlantis will be up on your left. Climb on.

Beware of the crowds on the weekends. Went there last weekend (11/07) and there were at least 20 people on this wall. One group had empty beer cans scatter at the base of the climb and were listening to heavy metal rock on their stereo which could have been heard from Indian Cove. (I have nothing against beer or music, just in moderation and in consideration to others). We left the wall to these wankers and headed to Lost Horse Wall... Nov 4, 2007

This crag gets good afternoons shade and morning sun.The enjoyment of many of the routes on the left side of Atantis is decreased by the fact that they are broken 1/2 way up by a big huge ledge and are either less protectable and less continuous, or done as two pitches of only 10-15 meters in length.
