The San Rafael Swell is Utah's least-known canyon system — 75 miles of slot canyons, hoodoo fields and reef trails between Castle Dale and Goblin Valley State Park. Side TRAX Rentals supplies four-seat Polaris RZR XP 1000s; the Behind the Reef Trail and Wedge Overlook are the picks. Goblin Valley night hike under International Dark Sky stars on day two. Decompression: a soak at Crystal Geyser cold-water tower and a rim drive at Capitol Reef NP before flying out of Salt Lake or Grand Junction.
Five quick questions, then we build the full itinerary — lodging, daily schedule, dining, bars, the group-chat message — and drop you into a Trip Room you can share with the crew.
