I had a great time on this hike and would recommend it to others. The guide was knowledge about Seattle and gave some great survival tips while we were out in nature in addition to very interesting facts about the plants and fungi we saw on the trail. The two hikes are not long, about 2 miles total, but be prepared because the Twin Falls hike is flat until the end when you ascend a steady incline for a while. It's not too bad, but it's something to be aware of. If you have the chance to do this hike, I say go.
