Tucked away in Alaska's Mendenhall Valley, the Mendenhall Glacier and its almost absurdly gorgeous ice caves promise an experience that's equal parts "National Geographic" and psychedelic album cover-think Pink Floyd meets polar explorer. Sure, crawling beneath thousands of tons of shimmering, painfully-blue ice might inspire a fleeting reconsideration of your life choices, but hey, life's short-why not spend an afternoon tempting fate beneath a melting geological marvel? Aim for early morning, when the tourist buses haven't yet disgorged their selfie-stick-wielding masses-meaning book at least two weeks ahead to secure your spot. Budget around $100 if you're DIYing it, or closer to $250 if you're hiring a guide (which, honestly, is wise unless your resume includes Arctic survival and ice spelunking). Dress like you're auditioning for Shackleton's Antarctic crew-layers, waterproof everything, and sturdy boots-and pack snacks that'll make your companions jealous while you're creeping through tunnels tinted like Smurf real estate. And while climate change is single-handedly shrinking these glaciers into oblivion, making this a tragically time-sensitive adventure, there's poetic justice in bearing witness while you still can-even if it's just to regale friends back home with tales of your frigid escapades beneath Alaska's shrinking, glittering belly.

Here's the dirty little secret about whale watching: it's mostly waiting around, holding overpriced binoculars as your boat bobs and pitches, surrounded by passengers who seem incapable of holding down their breakfast. Yet the moment a forty-ton humpback whale decides to breach the Alaskan waters of Auke Bay, arching gracefully through the cold mist with surreal elegance, you realize you've hit nature's jackpot. Aim for the early-morning trips-not just for the golden-hour glow, but because whales apparently enjoy dawn's serenity before hordes of tourists flood their turf. Book at least a week or two ahead, especially if you're picky about seats; budget around $150 per person, plus a little extra for a guide who actually knows more about whale biology than your Netflix account does. Pack layers and waterproof gear, and consider sneaking in a flask of something warming-just discreetly enough to avoid judgmental glares from the birdwatching couple from Nebraska seated behind you. Whale watching, at its heart, is about seeing something enormous, ancient, and indifferent to humanity itself; there's something oddly comforting in the knowledge that these creatures were swimming here long before Columbus got confused or Starbucks invaded every street corner. Worth it? Absolutely. Because standing on a crowded boat, staring slack-jawed and humbled at a whale breaching the surface while tourists fumble frantically with their cameras is the exact kind of glorious absurdity travel stories are built upon.
