Castle Mountain Lookout is a short but steep hike that provides sweeping views across the valley. It is a Stairmaster grind at the top but worth the effort.
Arnica Lake is a challenging winter stroll due to the elevation gain including a km long climb out of the valley at the end, but the sweeping views are amazing.
Despite doing this trail a number of times in the summer and winter we ended up taking a wrong turn at the start which added a half hour to the journey.
Fullerton Loop is a relatively short and easy trail that is close to Calgary and offers some nice vistas of the Kananaskis Range and along the Elbow River.
Lillian Lake is mostly in a treed valley, but it does offer picturesque views of Galatea Creek, numerous small waterfalls, and several majestic peaks, especially on the bluebird day that we had.
Rummel is always a fun jaunt that provides a decent workout without ripping the lungs out. On this overcast day, we weren't able to enjoy the usual mountain views.
