Table Mountain - Sacagawea and Papoose Rocks Loop (Heartbreak Ridge) via Pacific Crest Trail
This is a moderate loop trail to Sacagawea and Papoose Rocks in Gifford Pinchot National Forest.
This trail goes by Carpenters Lake. There are a number of excellent camping spots a few miles into the hike which will break up the in/out distance required to start the ascent of table mountain.
Please be sure to pack a lot of water and start early if you do this on a summer day, the top half of this hike is exposed south facing and heats up quickly.
Park at the Bonneville trailhead in Stevenson, WA and start the hike along the Tamanous trailhead towards the PCT. Make sure you have the proper passes or carry cash/check for the trailhead fee.
This would be a long and tough hike to complete in full with children, but would be a good hike to one of the lakes about 2-3 miles in.
