From Greg Tos via the TABVAR Facebook page:

Here is a nice topo from Gery Unterasinger who has done most of the work there.
The wall is just past Atlantis wall in Echo Canyon. The trail will need some work this spring but for now you can manage to get there and the climbing is well worth the effort.
Gery is a great photographer and story teller. Read more about Bellavista here: http://vertical-unlimited.smugmug.com/Rock-climbing/Bellavista/i-wvZttJG/A
