Water Depth
The quarry is deep in places, but depth can vary by ledge, line, visibility, and underwater shelves. No jump should be considered without current site permission and direct landing-zone inspection.

NO DIVING / SWIM AT OWN RISK*
Dorset Quarry is a seasonal managed quarry at 1848 Vermont Route 30. Check the official hours, waiver, signage, and no-diving rule before entering, and do not assume any ledge is approved for jumping.
The site is known, but the rules are explicit: cold quarry water, slick marble, no lifeguard, and posted no-diving language make this a rule-check-first listing.
Overview
Dorset Quarry is one of Vermonts best-known quarry swimming locations, but it is not an unmanaged free-for-all. The official site lists the address on Vermont Route 30, a Memorial Day to Columbus Day operating window, waiver flow, no lifeguard, and no-diving language. The public guidance keeps the 40-foot jump reference for context while shifting the public page toward current access rules, cold-water risk, slick marble, crowding, and careful use of permitted areas only.

Conditions and planning notes
The quarry is deep in places, but depth can vary by ledge, line, visibility, and underwater shelves. No jump should be considered without current site permission and direct landing-zone inspection.
Use the official Dorset Quarry address, hours, waiver process, parking details, and closure updates. Access is seasonal and managed, so older community descriptions are not enough.
Enter from the designated quarry access and parking flow only. Keep the page focused on official entry, swim areas, and neighborhood-respect expectations rather than informal ledge directions.
Cold quarry water, slick marble, abrupt underwater shelves, crowding, parking pressure, no lifeguard, seasonal closures, and no-diving rules.
Earlier jump reports reference quarry ledges, but the operator currently posts no-diving language. Treat every ledge as off-limits unless current on-site rules clearly say otherwise.
Cold water, slick marble, abrupt ledges, crowding, no lifeguard coverage, and posted no-diving language are the core safety concerns. Follow current operator rules and leave if conditions or signage are unclear.

Dorset Quarry sits around Dorset, Vermont, United States, putting this quarry-water spot in the orbit of Dorset and the broader Vermont area of United States. Use the saved coordinates and current map view as a starting point, then confirm the exact approach locally because cliff-jumping access can change around parks, private land, roads, shorelines, and water-management areas.
The best-season note is memorial day-columbus day, but that should still be checked against recent weather and water levels. Conditions are not static: rain, snowmelt, drought, changing water levels, current, and weekend crowding can all change what looks like the same jump from one visit to the next. Treat saved route notes as background, not as a present-day clearance to jump.
The main assumed risks include moving saltwater, hard exits, changing swell, hidden rocks, and delayed rescue access. Access may be seasonal, so parking, gates, trails, and enforcement should be checked close to the visit date. Before anyone climbs to a ledge, inspect the landing zone from the water, identify the exit, look for submerged rocks or debris, and be willing to walk away if the depth, footing, legality, or rescue options are uncertain.
