The first 1.8 km takes you through a dense forest of evergreens which climbs gradually for 117 m before it reaches the first of the Geraldine Lakes. The trail sticks close to the west shoreline, creating damp feet and frustration during high water, so try to veer slightly inland to stay dry. At the end of the first lake the path fades, becoming less and less conspicuous as the journey continues. From here on in, follow yellow markers and cairns and the bits and pieces of trail as it materializes.
Here at the end of the first lake is the first of two wonderful waterfalls encountered on this hike. Stay to the right and clamber up the side of the falls for 81 m, reaching a short valley. There is a second lake here, but it is not the second lake. Follow cairns and trail to the left side of this pond before walking alongside it through the trees. At the far left reach, the path scrambles up what feels like a perpendicular wall for another 202 m. This is a test for boot traction, as there is nothing to grasp and the hillside is loose pebbles and scree.
While creeping your way toward the next level you will undoubtedly stop to rest lungs and legs. Enjoy the moment by turning around and glancing north. Sit down and take a break; take as long as you want to take it all in.
On top of the waterfall the second lake comes into full view. There is much rock hopping and the trail is sparse. Stay low, avoiding the trails to the viewpoint up the right bank at the near end of the lake. The way to the campground is on the left (west) shoreline. The route is mainly rocks and boulders with some bits of trail through bush. As much as rock hopping is fun, it is dangerous. There is more than a kilometre of this to the campground at the distal inlet stream, so fatigue is also a consideration while playing on the rocks. The campground is primitive, with four or five pads, a bear pole and a privy.
Day hiking from this point is obvious but dangerous. There is no trail to the third and fourth lakes, and minor navigational skills may be required.
It seems hard to believe that with all the early exploration going on all around the Geraldine Lakes chain, it was not until the 1930s that someone set foot in this remarkable series of hanging valleys. Athabasca Pass and Whirlpool Campground are a measly 5 km over the next northern range, and the Fryatt Valley is only 8 km south of the lakes over Mount Fryatt. The outlet stream from the Geraldine Lakes entering the Athabasca River is so close to the Whirlpool and the Fryatt that it is difficult to understand how all of this was ignored or not found.
Regardless, the valley was first entered by Frank Wells sometime during his tenure as park warden for the Sunwapta district. He was given the position in 1924 and held it until at least 1936. It was in 1936 that he and his 12-year-old daughter, Geraldine, stocked the fishless lakes with fish.
