There was a lot of pent-up demand for trying the brand new Guinn's Pass trail, thus the Ramblers were able to mount two large groups within a week for this trip. This time, we had perfect summer weather (except that, like the first trip, the wind was so strong on the pass that it was not feasible to stop there for lunch). Unlike the 32 degree day in Calgary, it was quite pleasant, (24 at the trailhead at the end of the trip) with a gentle, cooling breeze and even a light, refreshing sprinkle at one point. Ten of the 13 summitted.
We all appreciated our tax dollars at work on this new trail. They were thinking well outside of the box on this one. The old route, which was incredibly steep and eroded before 2013, was obliterated by the 2013 flood. Rather than trying to build a new trail up this hopelessly loose and steep slope, they cut a new, well-engineered trail across the slope of the mountain, starting just east of Lower Galatea Lake and contouring around to the summit of the pass. Besides providing a better and more even grade, it also opens up fabulous views.

Although the route is good, I would recommend that this trail, and also the trail to Galatea Lakes, be upgraded to TL4 because of the long stretches of loose scree on these trails.

The route is long (18 km return with over 1,000 m of ascent), so I should have called the trip for 7:30, rather than 8:30, but we were back to the cars by 5:30.
