Clear freshwater spring with shore entry and cave access
Clear freshwater spring with shore entry and cave access
Blue Springs is a clear freshwater spring head in Merritt's Mill Pond with park-side shore access, a concrete dive platform, and an overhead cave system beneath the recreational basin. The open water is calm and highly transparent, but the site rewards careful buoyancy, strict overhead discipline, and planning around park rules and mixed swim traffic.

Depth range, seasonality, and planning context.
Best Season
Year-round, with cooler shoulder seasons usually more comfortable and summer the busiest.
Typical Conditions
Cold, highly transparent freshwater with gentle spring outflow near the head and calmer water away from the vent.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Do not enter overhead sections without cave training. Cold spring water, mixed swim traffic, and managed access make conservative planning important.
Access Restrictions
Park admission and county rules apply; cave access is restricted to properly certified divers, and pets are limited to service animals.
Legal Notes
Check current permit, hours, and access rules before arrival. The cave environment is restricted overhead space, not casual open-water terrain.
Community notes to help plan your visit.
Scuba Diving
Scuba is the main draw, but the overhead cave makes this an advanced site that demands cave-level discipline and access checks.
Freediving
Only the open basin is appropriate for freediving; overhead cave areas are off-limits without the right training and support.
Snorkeling
Snorkeling works best in the open spring basin and along the edge of the clear pool, away from overhead cave zones.
