What Key Locations Are Mapped In The Percy Jackson Series Books?

I still get a little giddy thinking of the places Rick Riordan scatters across the map in 'Percy Jackson & the Olympians'. If you want a quick list to pin on a fan map: Camp Half-Blood (Long Island) and Mount Olympus (above the Empire State Building) are the central hubs. The Underworld is placed under Los Angeles, while the Lotus Hotel and Casino is in Las Vegas — both memorable stops during Percy’s travels. The Sea of Monsters functions like the Bermuda Triangle, a dangerous stretch of ocean the heroes must cross in the second book.

Don’t forget the Labyrinth: it’s less a single spot and more a living network of tunnels and entrances that runs beneath much of the country, so I’d mark several entrance points rather than a single dot. For later crossovers you can add Camp Jupiter on the West Coast, plus smaller quest locations (islands, temples, and ruined landmarks) that spike the story at key beats. Pinning these on a real map turns the books into a road trip of mythic proportions — I always end up planning a fictional route and wishing I could visit them all.

I love geeking out with a map and a highlighter whenever I reread 'Percy Jackson & the Olympians' — the world feels built to be pinned. If I were drawing a fandom map, the absolute must-haves are Camp Half-Blood on Long Island (that whole camp, the cabin circle, Half-Blood Hill with Thalia’s pine tree), and Mount Olympus literally above the Empire State Building in Manhattan. Those two are the emotional and geographic anchors of the series: Olympus is the modern rooftop of the gods, and Camp Half-Blood is the hidden refuge on the East Coast where most of the series' training, drama, and cabin politics happen.

Then I’d mark the really cinematic travel spots. The Underworld sits beneath Los Angeles in 'The Lightning Thief' — that whole descent to Hades is tied to LA’s underbelly. The Lotus Hotel and Casino in Las Vegas (endless time trap — great place to pin for a moodier color) shows up as a weird, modern mythland. The Sea of Monsters is essentially the mythic version of the Bermuda Triangle — it’s where the quest in 'The Sea of Monsters' drifts into Polyphemus’s domain. And the Labyrinth deserves an entire layer on the map: it’s not one place but a shifting subterranean network that threads under huge swaths of the United States, with entrances popping up in unexpected real-world sites during 'The Battle of the Labyrinth'.

If I’m being generous with pins, I also add Camp Jupiter (the Roman camp from the later books — placed on the West Coast/Northern California area in the 'Heroes of Olympus' spin), various monster lairs and quest waypoints (Polyphemus's island, the Garden of the Hesperides moments, the St. Louis Arch cameo-type scenes), and several iconic one-off spots like the Gateway to the Underworld scenes, quest rendezvous (airports, dams, national parks), and local landmarks that become mythic in the narrative. When I map these I annotate chapters and mark cabin numbers and god-lines (who’s claiming what territory), because that’s where the story texture lives. Mapping the series is half nostalgia, half treasure hunt — every pin brings a line of dialogue or a chase sequence back to life on the page.
