Absolutely. Takes anywhere from 4 to 12 hours and isnt get technical especially during the summer months so basically anyone can do it assuming your are in reasonably decent shape.

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.
