Things to Do in Xiloá Lagoon

Sunrise kayak circuit

Paddling the eastern rim at dawn, you'll hear first truck gears grinding on the highway above while below the lake surface shows a perfect upside-down volcano. Flocks of black-necked stilts start piping overhead and the water, thick with minerals, feels almost syrupy against the paddle blade.

Sunday dock barbecue

Families claim floating wooden platforms and set up portable grills, sending threads of charcoal smoke across the water. You'll taste vinegary curtido on fried fish while tuba music echoes off the crater walls and kids leap, dripping, back into the turquoise.

Inner-tube stargazing drift

Night tubing here means lying back in a truck-inner-tube, ears half-submerged so every paddle stroke becomes a liquid drum beat. The Milky Way spills across the sky, and when a meteor cuts through the silence you'll hear distant cheers from other floaters scattered across the lagoon.

Cliff-jump at Las Cuevas

A fifteen-minute trail from the parking pull-off leads to a ten-meter ledge where the basalt drops straight into bottle-green water. Your bare feet grip warm volcanic grit, heart hammering louder than the distant motorbikes while turquoise swirls wait below.

Mud-pot foot mask

On the western shore a handful of geothermal vents burble gray clay that smells faintly of hard-boiled eggs. Smearing the cool mud on your calves and rinsing in the mineral lake leaves skin tingling, the same metallic taste coating your lips that you get from licking a battery - oddly satisfying.

Crater-rim hostel in the southern hamlet - hammock deck overhangs the water and someone's usually strumming a guitar at dusk

Weekend-only guesthouse on the eastern slope where you'll wake to the smell of nixtamal corn drifting from the neighbor's kitchen

Family cabin operation near Las Cuevas jump spot, solar showers and blackout nights when the inverter battery dies

Camping under the guanacastes by the scientific station - basic toilets, cold-water taps, and howler monkeys that start yelling at 4 a.m.

Budget hotel strip along the highway junction - concrete rooms facing the truck headlights. But the Wi-Fi reaches the balcony

Mid-range ecolodge hidden in the northern forest track where breakfast tastes of wood-fired beans and the lake view is filtered through banana leaves
