If you're looking for a quick hike to some great views this is it! The hike is 2.4 miles round-trip and the views are just superb. You can see Rainier, Granite Mtn, Red Mnt, Tinkham Peak, Lake Keechelus, and much more. The autumn colors are just stunning at this time of year. This Trail 1348, now published on Green Trails Map 207 revised 2002. If you want a longer hike you can start at Snoqualmie Pass on the PCT 2000, adding 12 miles to this hike, or you can detour to Twin Lakes, adding two miles. The hike up Mt. Catherine starts out on an old logging road and then quickly turns into a fairly well maintained trail. There are a few minor logs to cross and one of my humans got stung by a wasp, so watch out! There is a nice resting area where you can stop for a snack shortly before you reach the summit, but go on, the extra time to reach the summit is well worth it. The last 25 feet up to the summit are a bit treacherous, very steep; some mud but there is a cable to assist you. On the way down we found a side trail, about 20 feet south from where we came up, which avoided the steep, muddy ascent and joins back up with the main trail 50 feet down. We wanted to get a bit more of a hike in, so when we got back to the trailhead we walked about 50 feet east, down the logging road to rejoin Trail 1348 to Twin Lakes. We hiked about a quarter mile but then the trail started to get pretty wet and muddy and unfortunately we only brought our trail runners. I guess Twin Lakes is better left for another time. Twin Lakes also can be accessed from a second trail, 1303, which can be reached if you go further east back down the logging road for about a mile and a half. Possibly this trail may be in better shape, however we didn’t get a chance to try it. To get to the Mt. Catherine trailhead take exit 54 off I-90 to the Hyak ski-area. Go past the parking lots and continue along the logging road for almost five miles, the trailhead will be on your right.
