Now that spring has sprung, it's become much more comfortable (and sensible) to head north on vacation. What better way to take in the blooming landscape than by traveling at ground level? You can with Amtrak's "Weekend Getaway Fare" on its scenic Adirondack train between New York City and Montreal for $89 round-trip.Regular fares are $134 so that presents a saving of $45. However, due to blackout dates and the fact that the special fare is only available Thursday through Sunday until April 24, this fare is only realistically possible if you want to leave on April 20 and return April 24. If you just happen to have those very specific dates free, lucky you: you get to spend 10 hours traveling through through the lush wine country of the Hudson Valley and Adirondack Mountains, arriving in Montreal just in time for dinner. But hurry, the fare needs to be booked by April 21.
