So we were a bit afraid of this hike. 10.5 miles and 2100 foot elevation gain. Took the boat from Waterton to the trailhead (15 minute ride). It took us 3 hours to get to the lake. I'm not going to lie, it was not easy. We are in our 50s and in decent shape, but we made it. Crawling through the tunnel and up the rock wall with the cable wasn't nearly as bad as all the rocky switchbacks getting there. The lake is beautiful. Spent about 45 minutes there then had to head back in order to catch the boat back. 2.5 hours back down. (there was only one shuttle time running this time of year, 10am with a pickup at 530pm.) Did get to see a helicopter dumping water on the fire across the lake, which was kind of cool. Definitely a rest day tomorrow, as we leave Waterton and head to St. Mary.
We love to day-hike. We have been to all of these wonderfully scenic national parks/areas: Yellowstone, Grand Tetons, Yosemite, Sequoia/Kings Canyon, Bryce, Zion, Grand Canyon, Olympic, White Mountains,Big Sur, Rocky Mountains, North Carolina. Glacier and Waterton are up next!... full info
