The transitional seasons—those would be spring and autumn—are the best times of the year for epic hikes. Head to Europe for crisp autumn weather in Switzerland and Hungary. Travel to Africa, where everything is starting to bloom in Swaziland. Or find always-perfect temperatures off the coast in the Seychelles. Just be sure to bring plenty of water.

Somlóvásárhely: Continue heading east to hike a hill for views of a cliff and a chapel, visit the largest medieval castle in the country, explore a long cave, and return to your hotel for a cellar tour and a wine tasting overlooking the vineyards in Hungary.

Praslin Island: Trek through a nature reserve, find the world’s heaviest nut, see giant palm forests and vanilla trees, try to spot an elusive Seychelles black parrot, and swim off one of the most beautiful beaches in the world in the Seychelles.
