The whole way up is packed with great challenges, up up up you go, and once you get to the lake, take it in, then get on the next trail to loop around boulder lake, I went counter clockwise, so make sure you keep a close eye on the trail, finding the right trail can be a little tricky , once I got to the other side of the lake I ended up just sticking as close to the lake as I could, much easier to see where I was going, then before I knew it I was back at the beginning of the loop, boulder lake is beautiful!
