Tver Sand Quarry / Tverskoy / Konstantinovsky quarry is a flooded sand pit near Tver with a sheltered inland basin, shore access, and a bottom dotted with submerged objects that make it a training-friendly dive site. It is best known for clear freshwater, drysuit and ice practice, and steady drills rather than standout wildlife.

Safety Notes
Cold water and variable visibility are the main planning factors. Use appropriate thermal protection and keep close buddy spacing on training dives.
Access Restrictions
Shore access is the normal pattern, but the quarry is best treated as a cold-water training site.
Legal Notes
Follow quarry site rules and any club instructions on access days.
Community notes to help plan your visit.
Scuba Diving
The site is widely used for Try Scuba, Open Water, drysuit, and ice-diving practice.
Freediving
Not a first-choice freedive site; the quarry is better suited to scuba training and cold-water practice than casual breath-hold sessions.
Snorkeling
Snorkeling is of limited value except as a surface look around the basin; the site is mainly a scuba training quarry.
