I have to agree with all the previous reports of this trail, in that it is extremely well-maintained and has amazing views of Mount Baker and the surrounding area. This was our first hike in the Baker area and we thoroughly enjoyed it.
We drove the night before and slept at the trail head so we could get an early start as we were going to head down to the Oregon coast after this hike. Road up to the trail head was in pretty decent shape, any vehicle can do it although it does take half hour or so from the highway as you have to take it relatively slow.
Got a start on the trail at about 6 am, it was a perfect blue-bird morning, and the early start allowed us to have the trail and the view to ourselves. Took us about 2 hours to get to the glacier, the creek crossings took a little bit of navigating but were definitely manageable with not too much effort. Safest option may be just to go barefoot or with water shoes right through but we managed to rock hop without falling in.
We scrambled up about 100 m elevation or so past the end of the well-maintained trail, still a pretty obvious route though. We got as close to the Coleman glacier as we figured was safe, but there was quite a bit of melt going on. The water from the melt streams were definitely delicious. Saw a couple marmots and a hummingbird at the top, wildflowers were also amazing near the glacier.
I would highly recommend this hike to anybody and it is a short drive from the border so manageable for anyone in the lower mainland area as a day trip.
