There’s quite a surplus of tour operators in La Serena. Most of them have tours of the same sites, including: Parque Fray Jorge’s cloud forest, penguin watching on Islas Damas, and the Elqui Valley and its observatories. Prices and trip availability vary according to the time of year. Some excursions are not offered at all during the winter, so check with individual agencies for schedules and pricing. For starters, Terremolinos Travel Agency offers bike rentals and diving excursions and it’s located right next door to Talinay Expediciones, which offers a variety of adventure excursions.
