One word describes Alaska and that is "BIG!" This not only describes the state but the climbs that are in it. From the single-pitch climbs along the Seward Highway and trad climbing and bouldering in Hatcher Pass, to Denali, the tallest mountain in North America, Alaska has something to offer everyone from committing alpine mixed lines to 3000ft granite walls. One thing remains common in all of these areas, the climbing is wild, the approaches are often long and the best climbs are remote, and usually without cell coverage. On top of that, the season for climbing is short, and dedicated Alaskan climbers learn to embrace all disciplines from bouldering, to trad and bouldering to ice and alpine climbing. Even then when maximizing your opportunity  Weather in Alaska can change very quickly and temps can fluctuate 30 to 40 degrees in a day, especially in the mountains. Alaska receives warm weather currents from Japan as well as cold weather currents from the Arctic Circle. When the two collide it tends to get nasty, wet, and cold. 

Most outsiders will choose to fly to Alaska. If you're coming for the Alaskan experience you'll need to rent a car. If you are climbing exclusively in the Alaska range there are shuttle services to Talkeetna, where most trips will launch. Touch base with your guiding service if you're using one, or touch base with your flight service if you're not and they can probably point you in the right direction. 

One can also drive the Alcan highway, which is an adventure itself, but this isn't an option unless you plan to stay for several months, or you're doing the drive for the drive itself. 

The Alaska Marine Highway system is also another option for the adventurous, but even more so than the Alcan, this is an adventure itself and it can be cost prohibitive, especially if you want to bring your car.
