It is a 2.5 hour drive from either Antigua or Guatemala City. The beaches are full of interesting but awkward steep angles due to the strength of the pounding surf. The ocean floor here drops off very steeply after only 20- 40 feet, making the undertow here very strong; only strong swimmers should venture out very far. This topography also provides some nice waves for surfing. There are lifeguards on duty during the weekend. Don't forget to bring some sandals as the sand is of the black volcanic variety. It is a stunning feature for the beauty of it, but it is too hot to walk on after 10am. The beach is 50 - 80 feet wide and stretches for miles. It is busiest(not crowded by any measure) on Sunday with mostly Guatemalans.
By public bus:
Or you can take the Carretera al Pacífico from Escuintla - Taxisco - La Avellana and a ferry to Monterrico.

The turtle release is daily at 5:30pm during turtle season and is Q10 per baby turtle. This money goes to the Turtle Hatchery, to help buy eggs from locals in order to rebury them and conserve them until they can be hatched.
Tours are given by local guides, ask your hotel to recommend a good guide. Prices between Q50-100 depending on number of people and times of day, feel free to bargain with the guide. Tours are normally at 5:30am to catch the beautiful sunrise. On clear mornings, it is possible to see the volcanoes in the distance.
If coming from Antigua or Guatemala by car, head towards Carretera a Puerto Quetzal, and just after Super 24 (on your right) take a left turn towards "Taxisco" or the border with El Salvador. You will see a sign with animals on it on your right, just in front of the turn. Continue on this road until you reach Km 87.5. Just before this there will be a second bridge crossing the Maria Linda river, a wide right curve, a huge hydroelectric turbine mounted in a concrete base on your left (this is the road to the Aguacapa hydroelectric facility) and at the end of this portion, a sign will show that Auto Safari is near. This is the last curve before reaching the park.They accept all major forms of payment, including US$ and major credit cards. The park has over 105 different species, local and international, and its collection includes up to 1200 animals.

You should know that Monterrico is for relaxing, meeting people, having a meal or some drinks, and then relaxing some more. To put it plainly, there isn't much going on in Monterrico yet. The weekends-only night-life, internet cafe (2 as of June 2013) and mangrove swamp is pretty much it. At times there is a lot of litter along the main street, but as the town grows more tourist-aware, the local businesses have a campaign of cleanliness, including new garbage cans in public. The beaches are mostly clean, and the hotels between the Dulce y Salado and the Eco Beach place generally keep it the best. You can take a 2 hour boat tour of the mangrove swamp for $5. The main road leads from the beach to the mangrove swamp dock and is a pleasant little 10 minute walk. There are a few mosquitos at night and you will get bitten so bring repellent. Some hotel rooms have mosquito netting covering the bed, but not all. The waves at the beach have a short and dangerous break.
There are 2 internet cafes as of June 2013, and they charge Q12 an hour.
There is a Spanish language school.
Horses are available to ride on the beach.
Baby turtle release is one of the most fun activities. There are several places along the beach that collect eggs laid by sea turtles and when hatched, they will mass release all the turtles. Ask your hotel manager or locals for more information. Generally the laying and release season runs from June through March.
Affluent Guatemalans drive their ATVs up and down the beach. So do the police. Be aware.
More affluent folk fly their single or twin propeller plane in for the weekend and often fly low along the beach. There is a grassy landing strip along the main road, owned by the Aeroclub de Guatemala. Helicopters also fly along the beach once in a while, usually the affluent folk touring around before landing at their beach houses. If possible take an ATV ride along the beach, (west or east for about 10 Km) you will see some fascinating houses.
Not much here in the way of local textiles as in other regions of Guatemala, but there are some local specialties worth noting; this region grows and dries massive loofas (they can be found drying hanging from most any surface in early November). There is also a profusion of coconuts here, so plentiful in fact that they sit in big piles at the base of trees scattered all over town, and local merchants gather them and put them in big coolers. For 2Q you can have a freshly opened coconut with cool natural coconut milk inside, and then you can pour other drinks into it or smash it open and eat the coconut meat, which is delicious.
You may want to bring all the cash you need for your stay. There is one bank in town, a Banrural which are located on the road heading to Hawaii, where you can exchange US dollars (With your passport) cash traveler's checks and other banking needs like change. There is one ATM in Monterrico at the Banrural Bank and when it runs out of cash or is shut down it can be days before it's in service again. Some of the more expensive hotels have been known to exchange American Express travelers checks e.g. Johnnys Place, but they will not give you the best of exchange rates. Be warned VISA traveler's checks are not accepted anywhere in town. Many hotels now accept credit cards, with a 5% surcharge. Some hotels such as Hotel el Delfin and Johnny's Place exchange dollars, but the banks have better exchange rates.
Many of the hotels along the beach have restaurants. Some of the best are at the Hotels " El Delfin" (http://hotel-el-delfin.com), "Cafe del Sol", "Pez de Oro", "Johnnys" http://johnnysplacehotel.com/restaurant.php).
El Pelicano is the best high-end restaurant, run by a Swiss-German Chef/Owner. It is located behidn Johhny's Place. Note they are closed on Monday and Tuesday.
Food in most of the beach restaurants is more expensive, but dependable and you might feel much more comfortable depending on your level of travel exposure. The best part is, you get a great sunset almost everynight. Budget-food you get along Calle Principal. Here you will find a place selling chow mein tostadas for a bargain price. But be careful you can also get stomach problems. Vegetarian food is particularly hard to come by here with seafood being predominant on most menus.
On the main road from the beach to the mangrove dock street vendors sell chicken sandwiches for Q5 and fried chicken with fries for Q6. You can get a small slice of cake for Q2 at some of the local stores (tienda in Spanish). "'
The beach hotels usually operate with different prices for weekends-weekdays. On the weekends it can be difficult to get a room at your hotel of choice. Book ahead, or be prepared to walk along the beach asking for available rooms. Children often will greet you as you arrive by bus and show you the way to a hotel but they do not know about the availability of the rooms and will expect a small tip of some kind.
Monterrico is not safe for foreign tourists. The tourist police were withdrawn in recent years as they were unable to carry out their work effectively due to interference from local residents. There have been instances of rape and murder committed against foreign nationals in the town, occurring in broad daylight as well as at night. Foreign nationals should be aware of the alarmingly high rate of crime, and reconsider visiting the town.
Shuttles leave daily for Antigua at 4pm, tickets can be purchased on the Calle Principal at Calle Real Restaurant, or at Hotel el Delfin or Johnny's Place. Prices start at Q70 per person, and it is better to reserve the day ahead. Private shuttles to Guatemala City cost about Q800 or $100, depending on number of people and time of day. To head to Guatemala City, there are direct chicken busses at 5am, no ticket required. To head to El Salvador, it is easy to take the ferry to La Avellana and then a quick bus to Taxisco where there are frequent busses to the border. No tickets required. It is also possible to catch the shuttles in Taxisco that are going from Antigua to El Salvador Beaches, if your hotel will contact Global Surf in Antigua.  To head to Lake Atitlan, you can take a bus to Escuintla, then to Cocales and onto San Lucas Toliman.
