Flooded historic marble quarry pit with steep rock walls and green water in Dorset, Vermont.

First Time Here

The pin marks visitor parking on Vermont Route 30. Access is direct from the road with a short walk to the quarry. Entry is controlled on site—expect to show compliance with the operator’s registration or waiver process before you reach the water.

Complete the required visitor registration on the official Dorset Marble Quarry website (dorsetquarry.com) before you go when that is practical: it collects contact information and date of birth, and minors must be tied to a responsible adult’s entry. Always follow the current form, terms, and any on-site staff instructions—the site and social channels are the sources of truth when hours or closures change.

The pool is a flooded marble quarry: depth varies by location, water stays cold year-round, and rock ledges plus vertical walls mean real slipping and cold-shock risk. There are no lifeguards—swim at your own risk. Posted rules include no diving, no alcohol, no drugs, no motorized vehicles, and no unaccompanied minors.

Travel and social media often describe jumping from ledges here. The operator’s posted rules explicitly prohibit diving and do not read as permission to jump; treat ledge behavior as something you may see, not something this guide or posted rules guarantee is allowed. When in doubt, stay at the edge or skip the activity.

Should You Go

Good for

  • Swimmers who accept cold, deep quarry water and will follow waiver and on-site entry steps
  • Visitors planning around the posted Memorial Day–Columbus Day season and checking the official site for updates
  • Groups that include attentive adults for every minor, matching the no-unaccompanied-minors rule

Skip if

  • You need lifeguards, a shallow wading beach, or an unmanaged river bar
  • You cannot complete registration/waiver requirements or do not agree to operator terms
  • Cold water, heights, or crowded ledges are outside your comfort zone

Safety on site

This is private quarry recreation with on-site control, not a public pool. Cold water shock, slippery rock, and unknown depth underfoot are real hazards—enter slowly, test footing, and supervise minors within reach. Posted rules prohibit diving and unaccompanied minors; alcohol, drugs, and motorized vehicles are not allowed. Jumping from ledges is widely described by visitors and media but is not presented as permitted in the operator’s posted rule set—follow signage and staff. Hours and season can change; confirm on the official website before you drive. This guide is independent and not the operator or a legal source.
