One of Bastimentos' most fascinating natural wonders, Nivida is a massive cavern with swarms of nectar bats and a subterranean lake. The cave lies within the borders of the Parque Nacional Marino Isla Bastimentos and half the fun is getting here. But it's next to impossible to do it on your own. An organised tour from Old Bank costs US$35 per person.
The tour involves a 25-minute boat ride from Old Bank to the channel entrance. You'll then spend a similar amount of time gliding though mangroves and lush vegetation. From the dock it's then a half-hour hike to the cave. Wear sturdy shoes or boots; you will be provided with headlamps at the cave entrance.
