This rather steep universal access trail is a must
do walk while visiting the Johnston Ridge Observatory.
The trail is kinda steep, but paved and an excellent
way to view and learn about the Mt. St. Helens
phenomena. There are guided walks along this part
of the Boundary Trail, which begins at the observatory
and heads east to Mt. Adams.
