Hiked 8/12/17. This was my third time to the trail. First was up to Lake Mason; second we crawled over and under large trees blown down by winter storm for 3 miles just to trailhead and another 1.5 on the trail (total obstacle course); this time we went past lake up Mt Defiance. Defiance was challenging and wooded for part of it before exiting into a meadow that was filled with beautiful wild flowers. To reach the summit, the last ~150ft of gain was very steep.

People swimming in lake as we descended; nice campgrounds around lake area for backpackers. I only gave this trail 4 stars due to the crowds, but an awesome hike nevertheless!

Hiked 7/23/17 - BRING BUG SPRAY. We were blown away by how many cars were parked, but most were going to mason lake. Pretty busy all the way to the lake, not super hard hiking but makes you sweat. The last few miles to mount defiance were so beautiful, and minimal people. The last half mile is killer but totally worth it. The bugs were SO bad at the top, we rushed to take a few pictures and get out of there, they were even driving the dog nuts. Bugs at the lake were annoying but nothing compared to the peak. Overall super fun!

Hiked at night with flashlight to summit to watch sunrise. Total fog at sunrise and millions of biting flies on the top. Pretty coming back down though! Way too many day hikers coming up to Mason Lake.

Amazing Trail to Mason Lake. With the exception of the gigantic swarm of mosquitos that won't stop bothering you (bring a repellant☺).

Made it to the top of Mount Defiance but had to tread through quite a bit of snow. Trail is unsteady in a lot of areas but it's doable if you take caution.

Didn't make it to mount defiance cuz the snow is pretty unstable and I fell in a few times. I did go to lake mason and then came back and up the other side of the lake - awesome view! I did not want to leave : )

This was a great hike! There were a lot of potholes getting to the entrance so drive slow. Once you get on the trail the beginning had lots of fallen branches and debris. Past that the trail goes straight up. Kicks your butt!! I didn't make it to the lake because it snowed a couple days ago and it was too thick. Hope to go back in a few weeks when everything has melted. Made it 2.5 miles before turning around. Went up twice just for cardio and it was 9.8 miles round trip.
