Nestled in Pentagon Lagoon with postcard views of the monuments, Columbia Island Marina is DC’s only full-service marina just minutes from the National Mall. Managed by the Adventures Unbound team, it offers secure year-round slip...
This marina has built a genuinely loyal following, and it's easy to see why. Long-term boat owners rave about the staff's attentiveness and care, with one family crediting them as the reason they've kept their boat here for five years. The docks are well-maintained, the grounds are clean, and the boat launch ramp gets solid marks too. Beyond the boating side, it doubles as a surprisingly enjoyable destination on its own. Visitors stop by to walk around, grab a cold drink or slush, watch the boats, and even hike out to the Jefferson Memorial. The setting along the water gives it a relaxed, scenic vibe that keeps people coming back. The parking lot could use some attention, but that's a minor footnote in an otherwise consistently positive picture. With a beautiful location, solid amenities, and staff that people genuinely appreciate, this place earns its reputation as a hidden gem worth knowing about.
Rented kayaks here for two hours and did the full loop of Columbia Island. Great contrast between the peaceful nature of the first half, then popping out onto the Potomac to see the monuments and all the activity. Very friendly and helpful staff. Also excellent place to have lunch afterwards - really enjoyed our crab cakes and shrimp. Highly recommend this location if you want to experience kayaking in DC
