DejavoyBeen there, before you go.

HAWAIʻI · Oʻahu, Maui, Hawaiʻi Island, Kauaʻi

Rehearse your Hawaiʻi trip before you go

Each Hawaiian island has its own face: Waikīkī's city, volcanoes, canyons, and popular nature spots that now need reservations.

Dejavoy is a free game: plan a trip, then play it through day by day before you go, and catch closed days, missed bookings and tourist traps before they catch you.

Traps travellers fall into

In the game these hide among the recommendations. See if you can spot them.

  • The “free tour” booth Honolulu (Oʻahu)Waikīkī 'free' or 'half-price' booths usually require attending a timeshare sales presentation; it eats half a day
  • A photo with the parrots Honolulu (Oʻahu)Street photos with animals put on your shoulder come with a steep fee afterwards; say no up front
  • A swim at Waimea Bay in winter The North Shore (Oʻahu)November to March is big-wave season on the North Shore; check the lifeguard flags and stay out on red-flag days
  • The 'secret waterfall' on a map app MauiMany Road to Hāna waterfalls are on private land or dangerous; stick to the ones in parks with proper parking
  • The 'Kona blend' at a souvenir shop Kona (Hawaiʻi Island)'Kona blend' needs only 10% Kona beans; look for '100% Kona Coffee' on the label, or buy at a farm
  • A guide who'll 'take you right up to the lava' Hilo and Kīlauea (Hawaiʻi Island)'Tours' into Kīlauea's closed areas are illegal and life-threatening; watch the lava from the park's overlooks
  • Queen's Bath, the lava-rock pool KauaʻiQueen's Bath kills people every winter in high surf; avoid it October to April. The sign at the trail counts the dead
  • A turtle comes ashore Honolulu (Oʻahu)Hawaiʻi's turtles are protected by law: stay 3 m away and never touch. For monk seals, 15 m
  • At the trailhead parking lot Honolulu (Oʻahu)Car break-ins are common at Hawaiʻi trailheads and beaches: leave nothing valuable in the car, and stash things before you arrive, not in the lot
