Butterfly trip

Journey to Mexico's butterfly sanctuaries and stand among hundreds of millions of monarchs as they complete their remarkable migration. (Astrid Frisch, Natural Habitat Adventures)

We're all used to seeing the occasional monarch butterfly flitting about in the summer. And maybe you've visited a butterfly garden and seen them in greater numbers. But that can't compare to the experience of visiting Mexico's central highlands, where millions of monarchs migrate each year. There they cover the trees and other foliage in a carpet of orange and black. Natural Habitat Adventures offers six- and seven-day trips from January through early March to enjoy the spectacle. Both trips include outings, generally by horseback, into butterfly sanctuaries in the vicinity of the mountain village of Angangueo, west of Mexico City. The longer trip is aimed at photographers and includes an additional sanctuary visit plus tips from photography experts. In addition to the butterflies, there also is the chance to experience the culture of the mountain villages. The photography-related trip is priced from $3,495 per person double occupancy, and the other trip is from $2,995. Info: 800-543-8917, tinyurl.com/mt5efyk

How rail outraces jets

The popularity of train travel in the U.S. in contemporary times lags far behind planes or cars, but not so in Europe and much of the rest of the world. The people at Rail Europe, not surprisingly, think trains are far superior to air or highway travel. They have put together an infographic that compares the amount of time eaten up by traveling between popular European destinations when using these three modes. For instance, they say that traveling from city center to city center, the trip from London to Paris takes 2 hours and 15 minutes by rail, plus another 10 to 30 minutes for check-in. Flying, they claim, would take 4 hours and 50 minutes, which includes the estimated transfer and check-in times. Their estimate for a car or motor coach comes in at 5 hours and 10 minutes.
