Río Celeste and Tenorio Volcano National Park
NatureOpen

Places 1 to 2 hours away by road that you can visit and return from in a day, on your own or with a tour
This is for anyone based in La Fortuna for several days who wants a day out of town. Most trips take their own day, so choose by what interests you and by the day of the week. For turquoise water, Río Celeste and Tenorio Volcano National Park, about 73 km away: the trail is about 6 km round trip, around 3 hours, and entry is only from 8:00 to 14:00, so leave early. For birds, caimans and monkeys, Caño Negro Wildlife Refuge, about 91 km away, is toured by boat and takes the full day.
If you prefer something shorter, Proyecto Asís wildlife rescue is about 26 km away and its tours start at 8:30, 10:30 and 13:30; keep the other half of the day for Lake Arenal, which has no single entry point and is enjoyed with boat, kayak or paddleboard operators. Catarata del Toro waterfall, at Bajos del Toro, drops about 90 m inside an old crater, and the visit takes about 90 minutes including the descent.
Mind Sundays: Catarata del Toro and Proyecto Asís are closed, and Río Celeste or Caño Negro are the best option. The Jeep-boat-jeep to Monteverde is a one-way transfer: it only fits if you are moving on to Monteverde. Windsurfing and kitesurfing on Lake Arenal depend on the wind, from November to April; outside those months, switch to kayak or SUP. On a tight budget, Río Celeste costs $13.56, against about $76 for the full-day tour to Caño Negro.
