Lago della Piazza at the Gotthard Hospiz is a high-altitude lake dive located in the Maggia Valley of Switzerland. This shore-entry site offers a controlled environment for divers, with depths ranging between 10 and 20 metres. The water conditions are generally calm with no significant currents, providing a suitable setting for beginner divers to practise buoyancy and navigation. Visibility at the site typically fluctuates between 5 and 10 metres. As facilities are not confirmed on-site, divers should arrive fully prepared with all necessary equipment and air supplies. It is recommended to check locally for current access requirements before planning a visit.

Lago del Naret-Damm is a high-altitude reservoir in the Maggia Valley offering shore access to a calm, current-free freshwater environment. The site features a dramatic depth profile, ranging from 20 metres down to a maximum of 104 metres. Visibility typically fluctuates between 5 and 10 metres. Due to the significant depth and cold water temperatures, divers must use adequate thermal protection and monitor their gauges closely to manage nitrogen narcosis risks. While the site is accessible to beginners, they should remain in shallower sections to gain experience in alpine lake conditions. Parking is available on-site, providing a convenient space to prepare equipment.

Laghetti Superiore is a freshwater shore-entry dive located in the Maggia Valley. The site features a reef structure reaching depths of 15 to 20 metres, with an average depth of 17 metres. Visibility is generally good, ranging from 10 to 30 metres, allowing for clear observation of the underwater terrain. Divers can expect a typical dive duration of 40 minutes. Due to the cold water temperatures, adequate thermal protection such as a drysuit or a thick wetsuit is essential for all divers. The site is suitable for beginners, though personal thermal tolerance should be carefully assessed before entering the water.

Laghetto Naret is a high-altitude freshwater lake in the Maggia Valley, offering a calm environment for intermediate divers. The site features depths ranging from 20 to 30 metres with visibility typically between 5 and 10 metres. Entry is performed from the shore. Divers should be prepared for cold water temperatures and a pronounced thermocline, which requires the use of a drysuit or a thick, well-sealed wetsuit for adequate thermal protection. As facilities are limited, visitors should plan to be self-sufficient. The lake has no current, allowing for a controlled dive experience in a remote mountain setting.

Engstlensee-Bootsplatz is a high-altitude freshwater dive site in the Maggia Valley, Switzerland, offering shore access to depths between 20 and 49 metres. The environment is characterised by extremely cold water, with temperatures often dropping below 10°C and requiring dry suits or thick wetsuits. Visibility typically ranges from 5 to 10 metres. The site features no current, though divers must manage risks associated with significant depth, nitrogen narcosis, and potential decompression obligations. The habitat supports various temperate freshwater fish and invertebrates. Divers should plan conservative profiles within their certification limits and maintain strict buoyancy control throughout the dive.

Tannensee-Seemitte is a freshwater shore dive located in the Weggis-Vitznau area of Switzerland. This site offers a calm, current-free environment suitable for divers looking to practice buoyancy control at depth. The topography features a reef structure with depths ranging from 20 to 35 metres. Visibility at the site typically measures between 5 and 10 metres. As an alpine lake location, amenities can be limited or seasonal, so it is advisable to check for local facilities before arrival. The site is accessible for diving throughout the year, allowing visitors to plan their trip based on personal weather tolerance.

Tannensee-Rechte Dammseite is a freshwater dive site located along the right-hand dam side of the lake in Central Switzerland. Divers access the water via a direct shore entry from the dam. The site features a depth range of 20 to 35 metres, making it suitable for those looking to build experience in deeper freshwater environments. Conditions are generally calm with no current, and visibility typically ranges between 5 and 10 metres. Parking is available on site for convenience. As this is a deeper site, divers should maintain good buoyancy control and are advised to carry a surface marker buoy when exploring the outer limits of the range.

Melchsee-Grillstelle is an Alpine lake dive site situated at an altitude of 1,950 metres. Divers access the water via a straightforward shore entry to explore a reef structure that ranges from 8 to 18 metres in depth. The site is characterised by a lack of current and visibility typically between 5 and 10 metres. Due to the high altitude, water temperatures remain consistently low, often falling below 5°C. Appropriate thermal protection, such as a drysuit or a thick wetsuit with hood, gloves, and boots, is essential to mitigate the risk of hypothermia. On-site facilities include parking, toilets, showers, changing rooms, air fills, and a dive shop.
