This 29-hectare reserve was designed to preserve endangered flora and fauna of the Amazon, and functions as a center for environmental education. The extensive botanical gardens boast some 700 species of flora that can be visited on four differently themed tours (the botanical garden, sustainable processes, cultural scenarios and the aquarium), each lasting between 30 and 45 minutes.
You can combine as many tours as you like, and they'll even serve lunch for COP20,000 per person if you'd like to make a day of it. Only two guides speak English though, so it's a good idea to call ahead and book. To get here from Leticia take any bus to Km7.7 and then follow the sign off the main road down the track for 10 minutes.
