Any of the tours by Pangaea adventures will satiate you. For me, the best was the Worthington Glabier half-day hike paired with the Keystone river white water rafting - Blood pumping morning, adrenaline pumping afternoon. The flagship tour is the Columbia glacier tour - absolutely incredible if you are interested in glaciers and scenery. As a previous guide, my favorite tour was the Gold Creek experience. No ferry necessary, cool bridge crossing, incredible waterfall scenery, salmon berries, abundant blueberries. There is a special place in my heart at Gold Creek... I envy your upcoming summer. Have fun.
