Rain is possible all year round in the mountainous centre of the country and along the Caribbean coast but Costa Rica as a whole is usually less wet between December and April and most birds can be seen during this time, especially in the driest months of February and March which also fall within the periods when Resplendent Quetzal (Jan-Jul) and Three-wattled Bellbird (Mar-Jun) usually nest, although the peak time to see Bare-necked Umbrellabird at the lek is mid-April to mid-May. The main breeding season of the quetzal is March to June and this is the peak time to look for this extraordinary bird. Many other resident birds also nest in June and despite this period falling in the wetter season this is arguably a better time to look for species such as Snowcap. Quetzals usually migrate down the Pacific slope at Monteverde in June and Three-wattled Bellbirds normally congregate on the same slope in July. Bare-necked Umbrellabirds usually spend their non-breeding season (Jun-Mar) below 500 m on the Caribbean slope.
The best times to see turtles are July to December on the Pacific coast (when huge numbers of Olive Ridley Turtles usually come ashore around the last quarter of the moon each month, especially in September, October and November) and April to September on the Caribbean coast. The best time for whales is December and January.

Many trip reports, some for Costa Rica, are posted on the websites listed here. On some of these websites some reports are independent and some are posted by tour companies who organize tours to Costa Rica. These tour companies and others also post their own reports on their websites, which are listed under 'Some Organized Tours to Costa Rica' below.
The costs of organized tours partly reflect the quality of the tour leaders. Some leaders are certainly better than others and many companies claim their leaders are the best but even the best rely at least to some extent on the exceptional skills of the local guides they employ. If you are travelling independently, employing such local guides will greatly increase your chances of seeing the wildlife you wish to see.
There are many tour companies who organize tours to see mammals, birds, other wildlife and other natural wonders. The cost of these tours vary considerably according to such variables as the airlines used, the number of days the tours last, the number of sites visited, the number of people in the group (an important consideration if you wish to see such wildlife as rainforest mammals and birds), the number of tour leaders, the standard of accommodation and transport, and the percentage profit the company hopes to make. Generally, where the number of days tours last and the number of sites visited are similar, the cheapest tours are those that use the cheapest airlines, accommodation and local transport, that have the largest groups with the least number of leaders, and that make the least amount of profit. The most expensive tours tend to be those which are exceptionally long, use the most expensive accommodation (ridiculously lavish in some cases, even for single nights) and which make the most profit. Some tour costs partly reflect the quality of the tour leaders. Some leaders are certainly better than others and many companies claim their leaders are the best but even the best rely at least to some extent on the exceptional skills of the local guides they employ.
While tour companies organize tours with set itineraries many also organize custom tours for individuals and private groups who instead of taking a tour with a set itinerary want to follow their own itinerary to suit their own personal tastes, whether it be mammals, birds, other wildlife, other natural wonders or even man-made attractions, or a mixture of them all. Many organized tours with set itineraries are also fast-paced and target as many species as possible, whether they are mammals, birds or other wildlife or everything, which usually leaves little time to enjoy the best sites and individual species, but on a custom tour those taking part can specify the pace and the sites and species they wish to concentrate on. Custom tours also suit people who like to travel with people they already know, rather than with a group of strangers, and people with partners with different interests. Individuals and small groups will almost certainly have to pay more than the price of an organized tour with a set itinerary but a large group of friends may be able to travel for less than the price quoted for a set tour.
Tour companies who run organized tours or can arrange custom tours to Costa Rica include the following.
