Swimming Near Annapolis: Sandy Point, Mayo Beach and Lake Options

Annapolis-area swimming does not have to start with a search for an unnamed river pool. Sandy Point State Park and Mayo Beach Park both provide documented public beach access. They have different admission systems, staffing and schedules, so choose the beach first and check its rules before traveling.

If you specifically want a freshwater lake rather than Chesapeake Bay-area water, consider a separate trip to Cunningham Falls or Greenbrier. Do not use a reservoir, boat launch or waterfall as an automatic substitute.

Sandy Point State Park

Sandy Point State Park

Use 1100 East College Parkway, Annapolis, MD 21409. Swimming belongs in the designated beach areas, not at boat ramps or anywhere along the shoreline. The park publishes seasonal lifeguard coverage for part of South Beach; confirm coverage on arrival rather than assuming the whole beach is guarded.

Summer weekends and holidays require advance day-use reservations from Memorial Day through Labor Day. Admission is charged separately from any processing fee. Use the official park page for current rates and the state day-use booking system for your date. A fishing or boating access arrangement does not provide after-dark swimming permission.

Mayo Beach Park

Mayo Beach Park

Mayo Beach is at 4150 Honeysuckle Drive, Edgewater, MD 21037. The county identifies a public swimming beach, but there are no lifeguards. Check its beach rules and water-quality status before entering.

A free reservation pass is required on weekends and holidays between Memorial Day weekend and Labor Day weekend. Follow the reservation link on the county park page, rather than using the state-park booking system.

Weekday access changes during adaptive day camp. In the published 2026 schedule, June 22 through August 7 weekdays open to the public at 5:30 p.m. Check the current year's calendar before planning a daytime visit. The main beach approach includes a walk from parking, so pack gear you can carry and review the county's detailed accessibility information if needed.

Freshwater alternatives require a different trip

Cunningham Falls State Park offers designated swimming at Hunting Creek Lake during its Memorial Day weekend through Labor Day weekend season. Swimming at Cunningham Falls itself is prohibited, and the lake does not remain open for swimming simply because September weather is warm. Use the official Cunningham Falls rules.

Greenbrier State Park has a different season. Its swimming rules allow swimming only when swim ropes are installed, during the published first-weekend-of-May through last-weekend-of-September period. Check current conditions and reservation requirements.

These are alternatives for a planned lake trip, not promises of a quick drive from Annapolis. Check your route and traffic for the named entrance. A lake also has changing water conditions; freshwater does not mean risk-free.

Check water quality separately from admission

A reservation confirms an admission arrangement, not a clean-water result. Use the Anne Arundel County recreational water-quality page to reach current beach advisories and the swim guide. Check the location and sampling date instead of treating an old result as today's conditions.

County beach guidance calls for avoiding swimming and direct water contact for at least 48 hours after rainfall of half an inch or more. That is a minimum advisory period, not an automatic clearance after the clock runs out. Follow longer closures or site-specific instructions. The county also warns that jellyfish may occur at its swimming beaches.

If a beach is closed, choose a land-based outing or a separately checked swimming facility. Do not move to an unmonitored riverbank on the assumption that nearby water is unaffected.

Corrections to earlier river and waterfall advice

The previous guide described Mather Gorge as an option for experienced swimmers and unnamed Potomac pools as safer alternatives. Those recommendations were wrong. Great Falls Park prohibits swimming and wading, and Maryland-side Billy Goat Trail guidance warns of swimming penalties and dangerous river access. Plan views and trails, not a swim.

We have also withdrawn the old suggestions for unnamed Patuxent pools near Triadelphia and Rocky Gorge, broadly defined Patapsco river sections and unspecified Gunpowder entries. They lacked verified swimming access points. This is not a claim that every part of those rivers is closed; it means this guide does not establish permission at a particular entry. Consult the relevant land manager before relying on an old recommendation.

Swallow Falls is a separate western Maryland waterfall-viewing trip, not a verified family swimming recommendation. Maryland DNR's whitewater warning describes serious river hazards. Clear-looking water or a photo of someone swimming does not establish safe conditions.

Frequently asked questions

Is there a free beach option near Annapolis?

Mayo Beach publishes a free reservation pass for its summer weekends and holidays. Reserve through the county's linked system and check the date's operating schedule. Do not assume free access means no booking requirement.

Which option has lifeguards?

Sandy Point publishes seasonal coverage for part of South Beach. Mayo Beach has no lifeguards. For any site, verify staffing for the actual area and time you intend to use.

Can I use the same booking system for both beaches?

No. Sandy Point uses Maryland's state day-use reservation system. Mayo Beach directs visitors to its county-linked pass provider. Follow the official park page so you book the correct destination.

Are bay beaches freshwater swimming holes?

No. These are Chesapeake Bay-area beaches, not inland freshwater lakes. If a lake is important to your trip, compare the Cunningham Falls and Greenbrier options above, including their separate seasons.

Before you leave

Check opening hours, admission, any required pass and current water advisories. Bring sun protection, drinking water and a bag for your litter. Confirm the beach approach if accessibility matters to your group. Keep a non-swimming backup plan and follow posted closures even when older directory descriptions say otherwise.
