  • Great place to come visit for cool photo opportunities, pick-nicks, and learn about history. Amazing that there is a signature from 1806 in sandstone still readable today.
  • The views from the top are worth every step of the climb. The steps are many but not too steep. You can see for miles and see lots of wildlife. If you're lucky the marmots will entertain you. We went in May and it was beautiful.
  • A great overview of the Corps of Discovery in a very nicely done interpretative center. Even William Clark's carved name can be seen on the monument which is located in a beautiful natural setting.
  • Regular ranger guided walks or take a self guided tour anytime. They had a ranger stationed at Clark's signature to answer questions. Very easily accessible from the highway and worth a stop to stretch your legs on the steps.
  • Nice stop if you are in the area and want see a nice view and learn a bit about Lewis and Clark.
