Surprise Lake is a hidden gem that hikers can reach by trekking along the Amphitheater Lake Trail. The trail offers stunning views of the Jackson Hole valley, wildflowers, and two beautiful alpine lakes: Surprise Lake and Amphitheater Lake. Hikers might even spot some wildlife like deer and bears along the way. It's a great spot to take a breather, have lunch, and soak in the beauty of the Tetons before heading back down the same trail. And if you're up for a little extra adventure, you can climb up Disappointment Peak (advanced.)
