, climbs into the hills and the valleys are settled and largely deforested.
The Arima Valley remains as the westernmost valley that is still primarily forested, in a large part due to the presence of the
Asa Wright Nature Centre in this valley.
The hills rise abruptly from the lowlands of northern Trinidad (the so-called
East–West Corridor), but only the two tallest peaks,
El Cerro del Aripo and
El Tucuche top 900 m. The south-facing valleys run deep into the hills and support major rivers, such as the Caroni River, while the north-facing valleys are generally short and are drained by smaller streams.
There are numerous streams and waterfalls in the Northern Range. The highest waterfall is Maracas waterfall, towering 91.5 metres (300 ft) high. Other waterfalls include the Rincon Falls, Rio Seco Falls and Marianne Falls.
Geology
The Northern Range consists mainly of

Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or de ...

The country's largest cave system, the
Aripo Cave, is located in the Northern Range. The caves feature stalagmite and stalactite formations. These caves are inhabited by nocturnal
oilbirds, and bats.
Numerous sulphur springs occur on the river beds of Rio Seco Falls, demonstrating the volcanic nature of the region.
Ecology
The biodiversity within the Northern Range, which represents a combination of species from the South American continent and from the Caribbean islands further north is high. The densely forested peaks are home to over 100 species of mammals and 430 species of birds. Animals such as
red howler monkeys,
capuchin monkeys,
neotropical river otters,
collared peccary,
ocelot

On the summits of El Cerro del Aripo and El Tucuche, the vegetation is quite different from the lower montane forests. Elfin woodland and cloud forests cover the summits, and are home to the near endemic
El Tucuche golden tree frog.
