Fish Pass Jetties, located within Mustang Island State Park, consist of artificial reef structures accessible from the shore. These jetties offer a quieter alternative to nearby locations, though conditions vary significantly. Snorkellers should be prepared for moderate currents and potential hazards including jellyfish, rip currents, sharks, and surf. Visibility can be low, so the site is best explored on calm days when sediment has settled. Facilities at the park include parking, showers, and toilets. Due to the variable conditions and environmental factors, this site is rated 2/5 for snorkelling and is suitable for beginners who exercise caution regarding water safety.

Packery Channel North Jetty is a marine reef and artificial reef site located in the United States. This shore-entry location is suitable for beginners, with an average depth of 4 metres and a range of 2 to 5 metres. Divers should be aware of variable conditions, including moderate currents, surf, and visibility ranging from 3 to 9 metres. Hazards at this site include boat traffic, entanglement, jellyfish, rip currents, sharks, sharp coral, and strong currents. Facilities available at the site include parking, toilets, and showers. A typical dive lasts approximately 30 minutes. The site is rated 2 out of 5 for snorkelling.

Offshore Oil-Rig Platforms in the United States function as large-scale artificial reefs. These submerged steel structures span depths from 4 to 61 metres, with an average depth of 25 metres. Divers access these sites by boat, navigating structures that offer consistent 30-metre visibility. While mild currents are typical, strong currents can occur around legs and cross-members. Due to the depth, divers must manage decompression requirements and the risk of nitrogen narcosis. Hazards include boat traffic, entanglement in cables or debris, and the presence of sharks. Always confirm current access permissions for specific platforms before planning a dive.
