Best national parks for coast and islands
Some of the most striking national parks are defined by water: wild islands off California, the rainforest coast of the Pacific Northwest, the rocky shore of Maine, the coral reefs of Florida and the Caribbean, and a volcanic island in Hawaii. This guide ranks the best parks for coast and islands.
Short answer
Channel Islands ranks first for its wild, undeveloped islands off California, followed by Olympic for its rainforest coast, Redwood for its tall-tree shoreline, and Acadia for its classic rocky Maine coast. Biscayne, Dry Tortugas, Virgin Islands, and Haleakala round out the list with reefs, remote islands, and a volcanic Hawaiian coast. Most are best in their region's mild season.
How these coast and island parks were ranked
- Scenic payoff and how distinctive each shoreline or island is.
- Ease of access, since several require a boat, ferry, or flight.
- Range of activities, from hiking and tide pools to snorkeling and paddling.
- Season, since each region has its own mild and stormy windows.

- Best for
- Rialto and Ruby Beach, sea stacks, and tide pools

The classic rocky coastAcadia

The underwater parkBiscayne
- Best for
- Snorkeling, reefs, and boat tours off Miami
- Watch
- The park is mostly water, so you need a boat tour or your own vessel to see the best of it, and summer brings heat and storm risk.
Biscayne is almost entirely underwater, protecting coral reefs, mangrove shoreline, and the northern Florida Keys, best experienced on snorkeling and boat tours out of the Miami area.

The volcanic Hawaiian coastHaleakala
- Best for

Plan around the boats and ferries
Channel Islands, Biscayne, Dry Tortugas, and Virgin Islands all require a boat, ferry, or flight, and several book out far ahead, so reserve transport before anything else.
Match each park to its region's mild season
The Pacific coast parks are best in summer, Acadia shines in late summer and fall, and the Florida and Caribbean parks are most pleasant in the cooler, drier winter months.
Treat them as separate trips
These parks are scattered across the country and the Caribbean, so they are not a single loop. Group them by region and build a trip around one shoreline at a time.
