Lago di Tomé is a freshwater dive site in the Maggia Valley, Switzerland, offering shore access with on-site parking. The topography features a reef structure that descends from 20 to 40 metres, with an average depth of 30 metres. Visibility typically ranges between 5 and 10 metres and can fluctuate, making it advisable to stay near the reef line for orientation. While there is no current, the water is cold, remaining at 5-6°C below 20 metres year-round. Divers should use a dry suit or thick thermal protection. The site supports a variety of temperate freshwater fish and invertebrates typical of the region.

Pozzo del Diavolo is a freshwater river dive in the Maggia Valley, Switzerland. This shore-entry site features a reef structure reaching depths between 5 and 14 metres, with an average depth of 10 metres. Divers encounter moderate currents that require solid buoyancy control and awareness to avoid entanglement. Visibility is variable, ranging from 5 to 15 metres. Due to the cold water temperatures typical of mountain rivers, divers should monitor air consumption closely and carry a cutting tool. Conditions can shift rapidly, making it essential to check the current and visibility immediately before entering the water. This site is suited for intermediate divers.

Rio Salot-Wasserfall in the Verzasca Valley offers a shallow river dive with depths ranging from 5 to 10 metres. Divers access the water directly from the shore, encountering mild currents throughout the dive. Visibility at this location typically spans 5 to 15 metres. The site is suitable for intermediate divers who are comfortable navigating river environments. As facilities are not confirmed at the site, visitors should arrive self-sufficient with all necessary equipment and refreshments. The topography provides a straightforward navigation experience for those exploring this section of the Ticino rivers.

Lago del Sambuco-Sassello in the Maggia Valley offers a challenging deep freshwater dive. The site features a significant depth range from 20 to 110 metres, requiring advanced technical diving skills and careful gas management. Visibility typically ranges between 5 and 10 metres. The environment is characterised by extremely cold water, with temperatures between 3°C and 10°C year-round, making drysuit use essential. Divers can expect to encounter typical temperate freshwater fish and invertebrates within the habitat. Shore entry is available, and a cafe is located at the site. Due to the extreme depths and cold, divers must monitor bottom time and ascent rates closely to mitigate the risk of hypothermia and decompression issues.

Sassello is a freshwater reef site located in the Maggia Valley, Switzerland. The reef structure extends from the surface to a depth of 15 metres. Due to the presence of strong currents and rip currents, boat access is required to reach the site safely. Divers must be prepared for variable visibility and cold water conditions, which necessitate advanced buoyancy control and careful navigation. The site presents potential hazards including entanglement risks and overhead environments, requiring thorough pre-dive planning. Given the challenging nature of the currents and the need for precise depth management, this site is suitable for advanced divers only.

Verzasca-Pozzo San Rocco is a freshwater drift dive located in the Maggia Valley. This shallow site ranges from 3 to 5 metres in depth with visibility between 5 and 10 metres. Divers experience strong currents throughout the dive, requiring an intermediate skill level. Entry is via the shore, where divers must navigate a shore break and sharp rocks. The site features reef structures along the riverbed. Water temperatures remain cold, fluctuating from 5-10°C in winter to 15-20°C in summer. On-site facilities include parking, air fills, and equipment rental. Divers should confirm their exit point before entering the water due to the constant current.
