Why it works

The Santa Cruz Mountains' network of state parks and open space preserves offers extensive hiking and mountain biking accessible from the San Francisco Bay Area and Silicon Valley — a map covering the full range from the Skyline ridge to the coast is essential for planning point-to-point trips like the Skyline-to-the-Sea Trail. Big Basin's old-growth redwood groves and the trail network connecting multiple parks require detailed mapping to navigate efficiently. Waterproof construction survives the coastal fog and rain common in the Santa Cruz Mountains year-round.
