The closest major city is Liberia (Costa Rica).
It is 30 minutes by taxi from Liberia International Airport.
5 hours from San José (Costa Rica), 3 buses per day leaving San José at 8am, 2pm and 4pm and returning from Playas del Coco at 4am, 8am and 2pm. 1 hour from Liberia, buses every hour until 11am and then every 2.5 hours until 6:30pm. The bus company is called Pulmitan 2222-1650. It is possible to get to San José via Liberia if the direct services are full.
Every Tuesday and Friday there is a shuttle service that picks up from Tamarindo and brings riders to Playas del Coco for $20. This service is hosted by Pure Vibes (+506 2670 0273) that is based in Playas del Coco. They also offer $5 off accommodation at their resort () if you ride the shuttle.
It is a 4 hour drive from the Capital, San_José_(Costa_Rica).
Bus: There are buses that travel the roads between Coco and nearby beaches, but they are often crowded and uncomfortable.
Taxi: Depending on the season, from a handful to far too many to count local taxis will take you around Coco, as well as to nearby beaches, for anywhere from $2-10 dollars per trip. If you're only in Coco for a few days and don't want to invest in a rental car, this is your best option.
Rental Car: This is the best way to tour Coco and surrounding areas, and essential if you plan on staying more than a few days. It's recommended that you rent a 4x4, but a 4x4 is not necessary if you're a careful and competent off-road driver who understands the limitations of a car.
If you rent a car, you should be aware that all rental cars are easily identifiable by locals (rental cars use a different type of license plate). Therefore, you should NEVER leave any valuables unattended in your rental car, as they are constantly targeted by thieves. Also, local police can instantly identify a rental car and will not hesitate to pull over a tourist for speeding, so follow the speed limit closely.
This area of Costa Rica is short on historical attractions, museums, art galleries, etc. If you're in Coco, you're going to see beaches, wildlife, and enjoy the sun.
Popular beaches near Coco include Hermosa, Ocotal, Flamingo (incredibly popular with the locals on weekends), Panama, and a handful of remote beaches on the Papagayo peninsula (including the beach at the Four Season Papagayo). Further away, Tamarindo is an excellent surf beach for beginners, as well as a more commercialized beach town. If you're looking for something and can't find it in Coco, it's probably in Tamarindo (a little more than an hour away).
Downtown Coco beach is worth a look, especially after nightfall. You'll find drinking, dancing, and dining options, and even a couple of casinos.
Coco is also a great place to stay while exploring nearby natural wonders like the dormant volcano Rincon de la Vieja (about 1.5 hours driving time), Lllano de Cortes waterfall (about 2 hours drive time), and dozens of beaches within 1-2 hours drive (too many to mention, in fact). Jungle tours are also popular, and most of the local tour providers include a "zip line" tour as the main attraction.
Coco is fairly far away from Arenal, a recently active Volcano that is a must-see of any Costa Rica visit. Therefore, if you plan on staying in Coco, you might want to set aside two days of your trip to visit and stay at a resort near the Arenal volcano.
The main beach in Coco is under renovation with a new boardwalk but it is still not the best looking beach. However, it's a great place to rent a boat for an excursion to nearby "Gorilla rock" (also known as "monkey's head rock") as well as some mangrove swamps up the coast. A boat can also take you to some very good quality snorkeling just off-shore. If you decide to rent a boat, be sure to negotiate hard. Often times you will be asked to pay twice as much when you first ask for a price.
If you have a rental car, you can drive to either Ocotal or Hermosa beach. Both of these beaches are much cleaner and only 5-10 minutes drive away. If you're looking for a nicer beach and/or a longer trip, you can drive over to the Four Seasons Papagayo, park just outside the front gate, and then walk to the beach (in Costa Rica, all beaches are public, so they can't stop you from hanging out on their "private" beach).
There is company called Native's Way Guanacastethat based in Playas del Coco that has grouped all of the best tours of Guanacaste together and offer some of the lowest rates. Their National Park tours are amazing, they use guides that grew up on the volcano that know the land like the back of their hand. They can show you secret trails and point out wildlife you wouldn't have otherwise seen. But they also offer great canopy ziplining, sailing, tubing, stand up paddle boarding, you name it. They offer transportation and often a drink at the end of your tour. Definitely check them out if you want to know what is offered in the area
A local resident named Dr. Will  offers an early-morning wildlife tour that will introduce you to Costa Rica wildlife right under your nose. Will is a retired veterinarian who lives in nearby Ocotal and offers individual tours for $30-40 per person, depending on the group size.
Deep sea fishing excursions are definitely available as well - be sure to ask around on the beach in the late afternoon to find the best deal for the following day. You can also hire a boat to take you surfing off-shore near world famous Witch's Rock just up the coast from Coco. However, if you're new to surfing or not willing to invest in an all-day boat tour, you might consider driving about an hour to nearby Tamarindo. The surfing there is very good for beginners and kids.
There are many reputable dive companies in town including Summer-Salt, Deep Blue Diving , as well as the a new shop located in nearby Playa Ocotal called Rocket Frog Divers . All employ people who have great depth of knowledge of not only what is in the ocean but what you can find on land. This area is where tours often depart to visit the Bat Islands (Isla Murciealago) as well as the Catalinas. If you want to go sailing the Kuna Vela 
and Marlin Negro both are large charter sailboats with experienced and knowledgeble crews.
Finally, much like any tourist-oriented community in Costa Rica, you will find organized jungle tours that include zip-line rides. While there are half-a-dozen local tour operators and zip-line operations, you might consider visiting the Hacidenda Gauchipelin  for an all day package that includes a good quality zip line tour, and then your choice of a waterfall visit, a horseback ride, a soak in a mud bath, etc. Hacienda Guachipelin is about an hour away from Coco, but it's reasonable value and offers nice views of the dormant volcano Rincon de la Vieja.
Downtown Coco is the best place to find deals on clothes, souvenirs, and trinkets. While you can definitely negotiate prices, you may find that shop keepers are unwilling to work with you. Bare in mind that prices are different for tourists, so it never hurts to ask for the "Tico price" when buying any goods.
You can check out the local Coco classifieds site for used stuff and services here, 
Downtown Coco has some night life and quite a few restaurants. The Coconutz Sports Bar right on main street offers a wide selection of local and familiar foods.
A small cafe on the western edge of Coco called Pato Loco is a good place for breakfast or lunch, and there's a hamburger stand very close to Pato Loco that serves excellent yet inexpensive hamburgers.
You can expect above par service at this establishment and a very relaxed atmosphere while being here. We encourage that you plan to stay a little longer, as you will immediately feel at home when you enter our gates.
