Big Pine Key & The National Key Deer Refuge
Big Pine Key anchors the Lower Florida Keys at Mile Marker 30, located just 30 miles (35 minutes) east of Key West. Vastly different in character from the festive bar strips of Duval Street, Big Pine is an eco-tourism sanctuary defined by rare pine rockland forests, freshwater lenses, and the endangered miniature Key deer (Odocoileus virginianus clavium). Spanning over 9,200 protected acres, the National Key Deer Refuge offers peaceful walking trails, alligator viewing at the Blue Hole freshwater sinkhole, and the legendary off-the-grid No Name Pub. The wider island directory and travel planner starts on the Key West City Guide homepage.
Quick answer Spotting Key deer, speed limit enforcement, and Blue Hole
Read on 10 September 2026: Big Pine Key is located 30 miles east of Key West along US-1 (35-minute drive). Entry to the National Key Deer Refuge and the Blue Hole is free. Miniature Key deer (standing only 24 to 32 inches tall) roam residential roads and pine rocklands at dawn and dusk. Strict speed limits of 45 mph daytime and 35 mph nighttime are aggressively enforced by radar.
Key takeaways
- Observe strict speed limits: US-1 through Big Pine Key drops to 45 mph by day and 35 mph at night; tickets are expensive to protect endangered deer.
- Never feed Key deer: feeding human food makes deer approach roadways, leading to fatal vehicle strikes. Feeding is a federal offense carrying up to $5,000 in fines.
- Visit the Blue Hole: an abandoned limestone rock quarry filled with fresh water, hosting resident American alligators, softshell turtles, and green herons.
- Dine at No Name Pub: historic 1931 saloon on neighboring No Name Key whose walls and ceilings are papered with over $90,000 in signed one-dollar bills.

Encountering the endangered miniature Key deer
The Key deer is the smallest subspecies of the North American white-tailed deer. Isolated on the Lower Florida Keys following the retreat of Wisconsin-era glaciers over 10,000 years ago, the deer adapted to harsh island conditions through 'island dwarfism'. Adult bucks stand just 28 to 32 inches tall at the shoulder and weigh 60 to 75 pounds, while does weigh only 45 to 55 pounds.
Hunted nearly to extinction by the 1950s when fewer than 50 animals survived, the establishment of the National Key Deer Refuge in 1957 sparked an extraordinary conservation comeback. Today, a stable population of roughly 800 to 1,000 deer thrives on Big Pine Key and neighboring islands. They are gentle, naturally curious animals often seen grazing on native silver palm berries, sea grape leaves, and garden shrubs in quiet residential neighborhoods along Key Deer Boulevard and Wilder Road.
The Blue Hole: alligators in a freshwater quarry
Located two miles north of US-1 on Key Deer Boulevard, the Blue Hole is the only significant body of fresh water in the Florida Keys. Originally excavated in the 1920s as a limestone borrow pit to supply roadbed ballast for the Overseas Highway, the quarry tapped deep into Big Pine Key's unique freshwater lens.
A flat wooden boardwalk and observation deck overlook the deep blue water, which is inhabited by two resident American alligators, Florida softshell turtles, green iguanas, and schools of invasive blue tilapia. In the surrounding hardwood forest, look for white-crowned pigeons, red-bellied woodpeckers, and seasonal migrating warblers.
Dining at No Name Pub: $90,000 in dollar bills
Hidden on neighboring No Name Key (accessed via a short wooden bridge off Watson Boulevard), the No Name Pub is one of the most eccentric drinking establishments in the United States. Founded in 1931 as a general store and bait shop, it evolved into a tavern where local fishermen began stapling signed dollar bills to the walls in the 1970s so they would always have money for beer when returning from multi-day trips.
Today, every square inch of the walls, ceiling beams, lamps, and doorframes is covered in overlapping, autographed one-dollar bills—estimated at well over $90,000 in physical legal tender. The pub serves outstanding stone-baked tavern pizzas, smoked fish dip, and ice-cold pitcher beers.

Why are speed limits on Big Pine Key so strictly enforced?
