Forest bathing — shinrin-yoku in the Japanese it comes from — is not a hike. There is no summit, no distance to cover and no photo you are supposed to get. A guide takes a small group a short way into the trees and then slows everything down: what you can hear, what the air is doing on your skin, how the light changes when a cloud crosses. Sessions run 90 minutes and rarely cover more than a kilometre.
Costa Rica turns out to be an unusually good place to do it, because you can do it in three completely different forests inside one trip. You start in the humid lowland rainforest at the foot of Arenal, at about 400 m: loud, warm, full of things moving. You cross Lake Arenal and climb to the Monteverde cloud forest at 1,400 m, where the trees are shorter, hung with moss and bromeliads, and the forest is inside a cloud most mornings. Then you drop to the Pacific and stop walking altogether.
The pacing is the point. Four nights in one lodge, three in the next, three on the coast — no single-night stops, no 6 a.m. departures except the one for yoga. Everything is guided by naturalists from La Fortuna who have been walking these trails for years, and the whole thing is run by us directly, not resold.
