Mega ships going green

Carnival Corp. is going green in a big way with three new mega ships slated for delivery in 2020 and 2022. The Miami-based cruise company said Tuesday that the vessels will be powered by liquefied natural gas, considered to be the cleanest-burning fossil fuel. LNG-powered ships have become increasingly popular among cruise lines that have adopted a more eco-friendly strategy, partly because they satisfy stricter maritime rules that seek to limit harmful emissions.

Two of the new ships will be built for Carnival Cruise Line, making them the first LNG-powered ships in North America. The third ship will be for P&O Cruises UK.

Lose your phone

In a backlash against digital dependency, a number of tour operators are championing unplugged vacations. Intrepid Travel has announced Digital Detox Trips, in which participants pledge to swear off all devices including cellphones and cameras. They will receive a notebook in which to record impressions, and the trip leader will send daily e-mail updates to loved ones back home on request. The new eight- to 10-day trips visit Ecuador, India, Morocco and Thailand (from $630 a person). Meanwhile, much of rural Alaska is unconnected, a feature that Un-Cruise Adventures celebrates in its off-grid Alaska sailings (seven nights from $2,295) and Natural Habitat Adventures highlights in its eight-day Alaska’s Coastal Grizzlies: Kodiak to Katmai trip (from $8,995).

Big Sky cabin

At the 320 Guest Ranch in Big Sky, Mont., wake to the wide Montana sky and prepare for a day of hiking, horseback riding and fly fishing on a private stretch of the Gallatin River, made famous in the film “A River Runs Through It.” Don’t miss the weekly pig roast, or consider the wagon or horseback ride, culminating in a riverside barbecue. When the snow falls, cozy up in front of your riverfront cabin’s fireplace, snuggle on a sleigh ride or slap on the skis. Nearby Yellowstone National Park provides day trip options. Info:

The iPhone app “Sky Tripping” offers a collection of aerial videos that begin on the California coast and, for subscribers, take you to the Rocky Mountains; the red rocks of Sedona, Ariz.; the Sonoran desert and more. The aerial videos of sunset ocean views are indeed peaceful, and to hear the waves of the Pacific lapping at the shore is downright dreamy.
