About 1 hour 20 minutes outside of San Jose is Crocodile Bridge; a basically undeveloped but well-known tourist attraction. If you don't know it's there, you might miss it. Well, you might wonder what the tourists are doing on the bridge as you drive by.
Crossing the Río Tárcoles, there is an unremarkable 2-lane cement bridge with narrow raised "sidewalks" on both sides and a not-incredibly-high railing.
What IS remarkable is that the Río Tárcoles is said to have the highest concentration of American crocodiles (25 crocodiles per square kilometer) in the world!On any given day you're likely to see at least a dozen and up to 30 massive crocodiles swimming or lounging in the sun on either side of the bridge. Thankfully the bridge is very high so not only are you safe from a potentially fatal encounter with these guys, but the photo-snapping tourists don't bother the crocodiles. That said, apparently some tours and tourist bait the crocs by throwing food to them. I hope it goes without saying that you shouldn't participate in such idiocy.
One big one I saw, my driver said looked to be about 4 meters long. He also said there's an even bigger one in that area that's 6 meters! And they can easily weigh over 1,000 pounds. Yikes!!
There's a place to park on the north side of the bridge. There are souvenir stands, snack shops and a restaurant that also has a view of the crocs.
You want to be very careful when you go out on the bridge. There's not a lot of room between you and the speeding buses so you don't want to wear a backpack and only bring your camera so you don't accidentally drop anything over the side. A German tourist recently lost his passport off the bridge. Consider that not-recoverable.
The highly polluted river is usually brown with rain runoff, sewage, and industrial waste. Even though it's considered the most polluted river in Costa Rica, my driver who has been driving this road multiple times a week for 8 years, says that other times of the year you can see straight to the bottom allowing you to see even more of the scaly reptiles.
Aqua 4-in-1 Monterey Hammock Pool Float
Best pool floatie you can bring traveling. It packs small and is great for anyone! You can use it as a seat, a hammock, a noodle, whatever. Trust me on this one.
