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.

Engelberg: Start in a picture-perfect village, ride cable cars to a new hiking trail, see the reflection of the Alps in a crystal lake, follow an ice-cold river between stations, and celebrate the end of the day with a monastery beer, before the snow starts falling in Switzerland.

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.

Piggs Peak: Follow a footpath through the dry woodlands, meander around lowveld chestnut and fig trees, find a rushing stream with orchids growing alongside it, watch an African goshawk fly overhead, hear the whistling of a red forest duiker, and discover a beautiful waterfall in Swaziland.

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.
