The nearby waters teem with sailfish, marlin and wahoo, making Quepos one of the best spots along the Pacific for sports-fishing. Several operators run tours, including Luna Tours, in the lobby of Hotel Kamuk (from $380; t 2777-0725, w http://www.lunatours.net), and the pricier Bluefin, on the south side of the football field (from $575; t 2777-0000, w http://www.bluefinsportfishing.com). If you’d rather see the fish than catch them, Oceans Unlimited (t 2777-3171, w http://www.oceansunlimitedcr.com) runs half-day scuba-diving excursions ($139) and multi-day PADI courses (from $350), while MASS (t 2777-4842, w http://www.masurfschool.com) offers three-hour surfing lessons ($65) on Playa Espadilla in Manuel Antonio.
Inland options include white-water rafting tours with operator Amigos del Río (t 2777-0082, w http://www.amigosdelrio.net), who run tours to the Class II–III Río Savegre and Class III–IV Río Naranjo ($95 for the full day). There’s no shortage of canopy tours: Dreamforest Canopy ($60; t 2777-4567, w http://www.dreamforestcanopy.com) is the company of choice for adrenaline junkies, while the ride with Titi Canopy Tour ($55, $65 for their night canopy tour; t 2777-3130, w http://www.titicanopytour.com) is slower and more suitable for families.
The biggest operator in town is the friendly and reputable Lynch Travel (t 2777-1170, w http://www.lynchtravel.com). You can book white-water rafting and canopy tours through them, and their many local tours include horse rides to a waterfall ($65) and perennially popular daytime or sunset cruises, some specifically to see dolphins (both $75). They also run trips to Dominical, Corcovado and Bahía Drake, and can organize transfers to Panamá.
Iguana Tours (t 2777-2052, w http://www.iguanatours.com) can also arrange horseriding and white-water rafting, as well as hiking in Parque Nacional Manuel Antonio ($48, includes entrance fee) and boat and kayak trips around Isla Damas, a wildlife-rich mangrove estuary just north of Quepos (both $65).
