Located just thirty miles from Denver, Golden Gate Canyon State Park is an oasis of Rocky Mountain nature porn: aspen-rimmed meadows, verdant forests, jagged peaks, all crisscrossed by a well-maintained network of hiking trails. Also inside the park are two large campgrounds — Reverend's Ridge and Aspen Meadows — with scores of tent sites (and even a handful of yurts and cabins), allowing for multi-day escapes from Denver's concrete jungle. While you won't reach the level of isolation you'd find by backpacking farther out, Golden Gate Canyon is still a great option for car campers who want a break from the bustle of the city without having to drive too far. Reservations get snapped up quickly here, so book early.
