Early departure along the Pan-American Highway towards the city of Alajuela, stopping en route at the Doka coffee mill and plantation for an introduction to the traditional techniques used to produce Costa Rica's most celebrated export. Continuing up through the humid cloud forest that surrounds Poás volcano, you'll notice a change in the temperature and vegetation as the lush tropical foliage gives way to a more forbidding highland landscape.
Eventually you'll reach the impressive volcanic crater, spouting its potent sulphur fumes - it's an awe-inspiring panorama, and one of Costa Rica's most iconic vistas.
From the viewing platform overlooking the crater, begin the hike down to Botos lagoon, before continuing on to La Paz Waterfall Gardens to follow trails through the forest past a succession of waterfalls plunging through tropical greenery. Within these gardens there is also a butterfly observatory, a serpentarium, a bird house and a series of hummingbird feeders where you can photograph the tiny birds at close range.
