Map — The Cornfield Swimming Hole | New England Swimming Holes

Informal shoulder parking on a busy corridor. Route 30 and I-91 carry heavy traffic—never block lanes or the underpass.

Start here

Coordinates point to the roadside pull-off at the end of the guardrail after the I-91 underpass (northbound). Cross-check satellite imagery and what you see before you stop—this is not official parking.

Parking

Use only the informal pull-off along Route 30 described in intake: end of guardrail, immediately after the I-91 underpass when northbound. There is no designated lot. If the shoulder is full, unsafe, or posted against stopping, choose another day or site.

Rock River Swimming HolesSwim: allowed. Neighbor-run guide (rockrivervt.com) points to signed recreation pull-offs on Vermont Route 30 near Depot Road on the Dummerston side; short rocky trail (~5–10 minutes) to pools along Rock River. Parking is limited on warm weekends—use only marked pull-offs and respect driveways between the road and the river. Mountain-fed pools with slick ledges; flow can rise fast after rain. Mixed-use and clothing-optional customs exist upstream—read the site guidelines before you go. No lifeguards; cold water year-round.View guide →
Salmon Hole (West River)Swim: allowed. Salmon Hole is a developed swimming beach on the West River inside **Jamaica State Park** (commonly listed near **48 Salmon Hole Lane**, Jamaica). Pay park day-use fees and follow **Vermont State Parks** hours, parking, and posted swim rules. Coordinates match the published **48 Salmon Hole Lane** park entrance—match the entrance gate and signage in the field. Cold moving river water; current and depth shift after rain. Wet rock and cobble stay slippery. Lifeguards are **not** guaranteed—treat as open river. Stay inside posted swim areas, supervise children within reach, and follow all park signage.View guide →
Brockways Mills GorgeSwim: not recommended. Regional trip reports describe a **circular parking area on Brockways Mills Road** at the Williams River dam and cascade complex in **Rockingham** (Windham County), with a short steep path to mid- and lower-pool views. Stay clear of dam infrastructure, penstocks, and any posted utility zones. **Primary map coordinates** use the published trailhead / parking GPS from regional waterfall references (not the USGS streamgage pin). Cold water; slick rock on steep banks. Current increases after rain; keep distance from dam works. No lifeguards—supervise children closely and do not assume calm surface water means safe depth.View guide →
Cavendish GorgeSwim: not recommended. Recreation summaries for **Cavendish Gorge** on the **Black River** describe short foot access near the historic hydropower corridor off **VT Route 131** (parking and posting change—read **Cavendish Connects** and any DEC or utility signage the day you visit). Coordinates match the USGS monitoring point on the Black River in Cavendish as a defensible river pin; adjust after field verification if a trailhead lot is preferred. Cold moving water; slippery bedrock and moss common. Current and debris increase after storms. No lifeguards—supervise children within reach and avoid dam infrastructure and posted hazard zones.View guide →
Dorset QuarrySwim: allowed. Flooded marble quarry off Vermont Route 30 near Dorset: managed summer season, waiver required, short walk from parking to deep cold water, rock ledges and vertical walls—no lifeguards, posted rules include no diving and no unaccompanied minors; jumping is often described in travel coverage but is not framed as permitted in the operator’s posted rules.View guide →
Clarendon GorgeSwim: not recommended. **Lower Clarendon Gorge** on the Mill River is Vermont **FPR** public land (listed as Lower Clarendon Gorge State Park / State Forest depending on the official page). Vermont River Conservancy summaries describe parking along **Gorge Road** and a foot approach on an old roadbed toward the river—confirm the current **fpr.vermont.gov** trail map, gate status, and any seasonal closures before you go. Coordinates center **Gorge Road** in East Clarendon as a road reference—parking may be spread along the shoulder, so read each sign before you stop. Cold water and powerful hydraulics are possible after rain; wet schist and ledges stay slippery. There are no lifeguards. Cliff jumping is a personal risk choice—verify depth and hazards yourself. Supervise children closely and stay within your group’s skill level.View guide →
