The site is rated 1/5 for snorkelling, and sessions typically last up to 120 minutes.

Grenada Landing is an artificial reef site located within Grenada Lake. The area features a long sandy shoreline and designated buoy lines for swimmers. Access is via a shore entry.

Facilities available at the site include parking and toilets. Given the limited visibility, this location is primarily used for swimming rather than underwater observation.
