Boulder Islands

Overview

The Boulder Islands are a cluster of small, undeveloped isles in the Boulder Basin—places you reach by kayak or boat and then have largely to yourself. Think primitive shorelines, stark desert rock, and big-sky views. There are no services here, so plan like a backcountry day on the water.

Getting There & Facilities

You access the islands by water only. Use onshore facilities at Boulder Beach or Hemenway before you launch, then treat the islands as primitive stops. There are no restrooms and no potable water. Pack out all trash and, where required along the shoreline, use a waste‑containment system.

Safety Essentials

The lake has no lifeguards. Conditions can turn dangerous quickly due to high winds, cold‑shock pockets of water, and hazards exposed by receding water levels. Inflatable pool toys are banned because they can deflate or blow away. Avoid water with bright green or blue‑green algae. In hot months, any hiking or scrambling you do on the islands should be limited to early or late in the day, with plenty of water.

What You Can Do

• Paddle or boat to quiet coves and enjoy low‑key shoreline time.
• Fish from shore or boat—with the appropriate state license for the waters you’re on.
• Rent kayaks or small boats from private concessions in the area if you don’t have your own.

Regulations to Know

Motorized vessels require proper passes and compliance with state rules. Fishing and hunting each require the correct state licenses and tags where applicable. Follow Leave No Trace principles and pack out human waste where required.

Best Time to Visit

Cooler seasons are the sweet spot for comfort and safety. In late spring through early fall, plan any on‑island walking for early morning or evening to avoid extreme heat. Always check the wind forecast before committing to a paddle, and skip the pool toys—bring proper flotation instead.
