Short answer: The three 2027 projects worth planning around are Thrill Glider at Six Flags Magic Mountain, the Indiana Jones adventure in the Tropical Americas area at Disney's Animal Kingdom, and Monstropolis at Disney's Hollywood Studios. A family land at Six Flags Great America offers another option for anyone traveling with young children.
New coasters announced for 2027
Six Flags Magic Mountain has announced Thrill Glider, billed as the world's first "thrillglider" coaster, for 2027 (source). The park already has one of the densest coaster lineups anywhere — see the full Six Flags Magic Mountain guide for its current offerings.
Six Flags Great America has revealed Camp Timber Trail, a family area anchored by the suspended coaster Sky Hawk, also for 2027 (source). Six Flags Great America (United States) is not in our ranked Top 50 — we rank parks only once we have a full season of visitor ratings, wait-time data and pricing data.
New theme park lands under construction
At Disney's Animal Kingdom, the Tropical Americas area, including an Indiana Jones attraction, is taking shape ahead of a likely 2027 debut (source).
Monstropolis, with its "door coaster," is targeting a phased 2027 opening at Disney's Hollywood Studios (United States) — a park we do not rank (source).
Six Flags Qiddiya City: A recent park opening
Six Flags Qiddiya City (Saudi Arabia) opened on 31 December 2025 with 28 rides, including Falcons Flight (source). It is not yet ranked because it is too new for our methodology, so treat its opening as news rather than a ranked recommendation.
Opening-year visits: When to plan your trip
Opening seasons bring the longest lines of a ride's life. If the new attraction is the reason for your trip, go; if it is a bonus, the second season usually offers a far better visit.
