We're heading to Alaska's most popular and accessible national park. Along the way, we solve the mystery of the missing memory card, meet the cutest national park employees in the world, and take on the challenge of joining Denali’s 30% club.

We’ve reached our final park, but celebrations are subdued as we can’t take our eyes off the view outside. Lake Clark's coastal mountain scenery is one of the most beautiful things I've ever seen. On the ground, we watch brown bears digging for clams and grazing in meadows—at one point, we spot 27 bears at once!
