You have to exercise caution when renting a car in Costa Rica; where it is not uncommon for rental companies to claim "damage" they insist you inflicted on the vehicle. It is by far the best policy to rent a car through a Costa Rican travel agent. If you are travelling on a package, your agent will sort this out. Otherwise, go into an ICT-accredited travel agent in San Jose and ask them to arrange rental for you. This should be no more expensive than renting on your own and will help guard against false claims of damage and other accusations; rental companies will be less willing to make trouble with an agent who regularly sends them clients than with individual customers who they may not see again.
Never participate in adventure sports alone. Always carry identification and let others know where you are at all times. Before kayaking and rafting, check river conditions and wear a life jacket and helmet. Even popular rafting locations such as the Rio Naranjo near Quepos can become extremely dangerous in flash flood conditions. When hiking, rappelling, or climbing, carry a first aid kit and know the location of the nearest rescue center. Observe all local or park regulations and exercise caution in unfamiliar surroundings.
What better way to learn Spanish than by spending time in a Latin American country?

The coasts of Costa Rica are known for strong currents and rip-tides in some areas but most of them are great to be with the family. Costa Rica has some of the best beaches in the world. The Atlantic coast is just five hours away from the Pacific one and both offer completely different views and landscapes. There are no signs indicating an unsafe beach due to riptides, so take precautions and listen to the locals on where it is safe to swim. The public beaches do not have life guards. A traveler should learn how to swim out of a rip tide and not swim alone. There are some active volcanoes in Costa Rica and they are dangerous, so follow the warning signs posted. The slopes of the Arenal volcano invite visitors to climb closer to the summit, but there have been fatalities in the past with unseen gas chambers. Also be wary of the climate of Costa Rica. It is very hot in the daytime, but in the morning and evening it becomes very cool, so you should bring a light weight jacket.
Many travelers who enjoy nature vacations have scuba-diving experiences at the top of their list. Among the coolest places to visit in Costa Rica there are lots of amazing spots to explore under the water. One of the top picks is Drake Bay.

He discovered it in the 16th century, during his voyage around the globe.
Crude oil - proved reserves: This entry is the stock of proved reserves of crude oil, in barrels (bbl).

Stone tools, the oldest evidence of human occupation in Costa Rica, are associated with the arrival of various groups of hunter-gatherers about 10,000 to 7,000 years BCE in the Turrialba Valley. The presence of Clovis culture type spearheads and arrows from South America opens the possibility that, in this area, two different cultures coexisted.
