Wannabe botanists likely will enjoy a visit to Gunung Gading National Park where the world’s largest flower grows. Rafflesia blooms can grow up to three feet in diameter, and have a nasty smell. The blooms die after a few days; the good news is they can bloom anytime of the year, though the best time is November through January. But there’s more to see than just one flower. The Sarawak park has nice beaches, rugged mountains and jungles just made for hiking.
