La Posada del Tope Tours
There is no bus service to Rincón de la Vieja, but La Posada del Tope Tours arranges shuttle-van transportation to the Las Pailas park entrance for $20 round-trip per person, leaving Liberia at 7 am and returning from the park at 4 pm. This guesthouse is also the only place where you can buy tickets for the Tica bus heading north to Nicaragua. Their transportation services are recommended, but the hostel is not.
