Planning Your Visit

The optimal hiking season runs from April through October, when weather conditions are most favorable and daylight hours extended. Spring brings wildflower blooms and mild temperatures, while autumn offers stunning foliage colors. Coastal areas can be hiked year-round but require attention to tide schedules and weather conditions. Essential equipment includes waterproof gear, sturdy hiking boots for rocky coastal terrain, and layers for changeable maritime weather. Public transportation connects major towns, though a car provides greater flexibility for accessing remote trailheads.
