Definitely. It's a fun and "easy" (as in non technical) climb. The winter route is a bit longer (12mi round trip, 5000' elevation gain) than the summer route (about 10mi RT, 4000 EG iirc). Depending in the time of the year, you may need a permit. It's a favorite of the locals.

The inside of the crater is off limits. You can climb to the summit using the south route and some people ski down back to the trailhead.
