Filled with everything from glaciers and fjords to bears and whales, Alaska is, unsurprisingly, one of the most popular destinations for cruisers. The 49th state, often referred to as The Last Frontier (state motto: "North to the Future"), boasts millions of acres of untouched wilderness, and there's no better way to immerse yourself in the stunning scenery than to be surrounded by it on a ship.

With something for everyone to do on both land and sea, an Alaska cruise is the perfect multigenerational vacation. Twenty years ago, my husband and I took our kids on a cruise to Alaska, and it turned us into cruisers. Today, many cruises later, ships are better than ever, adding even more experiences, restaurants and stateroom options.

Almost every cruise line features dozens of onboard activities, including live entertainment, pools, spas, endless dining and kids' clubs, so you'll never be bored, whichever ship you choose. Many even offer guest lectures about the ports you'll be visiting, as well as serving up locally inspired dishes like fresh seafood chowder and crab cakes. On an Alaska cruise, specifically, it's worth splurging on a stateroom with a balcony if you can, because one of the best ways to spend an afternoon at sea is simply sitting outside and taking in the magical views. You may even spot an orca or a humpback whale!

Although you'll be tempted to never get off the ship, be sure to sign up for shore excursions to best experience Alaska's history, natural beauty and wildlife. Two must-do's on any Alaska cruise are dog-sledding and panning for gold. Because these family-friendly activities are available in numerous ports, though, I suggest first booking port-specific shore excursions that you can't do anywhere else and then filling in the rest of your schedule around them. Here are the ones you won't want to miss.
