We had hiked to Dock Butte a few weeks ago on a "partly sunny" day that ended with heavy rain. Even then it was apparent that this trail offers
amazing rewards, and we vowed to return on a good, clear day. Last Sunday was just that, so back we went. With regard to finding the trailhead, after leaving Baker Lake Road, keep following signs to "Blue Lake." When you are getting fairly near the trailhead, perhaps a mile or so before it, there is an unmarked fork in the road -- be sure to keep to the right and soon you will reach the trailhead at the end of the road. Dock Butte offers fabulous 360-degree views, making it one of the best and most easily-reached vantage points in the North Cascades, in my opinion. As you approach the Butte, there is a fork in the trail; you can bear right and use the gradual switchbacks to get to the top, or head straight up the ridge to the top. This time I decided to go right up the ridge, and didn't have any problem (I had brought poles, which were a definite help.). The view of Mt. Baker in particular was superb, but Baker was just the cherry on top of the cake! There were lots of blueberries along the trail, which compensated for the numerous bugs (they were worst at the top, unfortunately, so after spending a few minutes drinking in the views at the very top, we descended a short ways and found a shady area where we ate lunch). On the descent, a quarter of a mile before reaching the trailhead we saw the turn-off to Blue Lake, and hiked the half-mile to reach it. It's a very beautiful lake, more green than blue, but very clean and after a sweaty hike, quite irresistible. We enjoyed a delightful swim in the chilly (but not frigid) waters, before returning refreshed to the trailhead. (The rangers were writing out warnings for those who did not have the required National Pass, so be sure to have either the National Senior Pass or a Day Pass on your dashboard or hanging from your rearview mirror. The WA State Parks Pass is not valid here -- you must have a National Pass.)
