Things get more active than a geothermal field at this huge hostel that's ever popular with partying backpackers, especially when nights get flowing at the trashy Lava Bar. Dorms can be tight (up to 10 beds) and the lounges are concrete boxes, but extras such as female-only dorms, en suites attached to most rooms and a thermally heated pool compensate.
