[5][6] Spaans Lagoen stretches approximately 2 kilometres (1.2 mi) in length and ranges in width from 200 to 500 metres (660 to 1,640 ft) wide,[6] covering an area of 70 hectares (170 acres).

Evidence of human activity, including charcoal deposits, has been found in sediment layers at Frenchman's Pass (Spaans Lagoen) dating to around 1000 BC.

[3] The shores of Spaans Lagoen Bay, lined with mangroves, play a crucial role in preserving the region's biological diversity.

[3] The mudflats in the inland section of the Spaans Lagoen border the mangrove forest and experience daily tidal inundation.

Additionally, during the rainy season, land crabs can be observed crossing the mudflats in search of water to lay their eggs.

Roois often feature fertile soil and a high water table, making them ideal for fruit trees like Sweet Tamarind and Spanish Lime.

Shaded areas within roois can retain water for longer periods, serving as oasis for land animals like Eastern Cottontail Rabbits and supporting diverse aquatic life, including various species of Dragonflies and the Colombian Four-eyed Frog.

Similar habitats are found here, featuring various types of cacti and iconic endemic species like the Aruban Rattlesnake (Crotalus unicolor) and Brown-throated Parakeet (Eupsittula pertinax).
