Not only is Isla Isabela the largest Galápagos island, but its imposing skyline of grumbling volcanoes makes it the most striking. Volcán Wolf, at the northern tip of the island, is the highest point in the Galápagos, standing at 1707m (5600ft), and is one of the most active volcanoes in the archipelago – young lava covers the caldera floor. Ten eruptions have occurred between 1797 and 1982. The 1982 eruption saw fountains of lava emanating from vents before rising over the rim.
