Geikie Inlet is a saltwater inlet within Glacier Bay National Park in Alaska, forming part of the park's West Arm. The paddling environment here is profoundly remote and wilderness-focused, with no cell phone service and no quick rescue available, requiring paddlers to be self-sufficient and well-equipped. Access is typically by boat drop-off, with one noted kayaker drop-off location, and there are no roadside launches. The inlet features significant tidal dynamics, with a tide range of up to 20 feet, making careful planning around tidal currents and landings essential. The shoreline includes coves like Shag Cove, which is a fair-weather anchorage and offers some protection. The area is exposed to the larger forces of Glacier Bay, and paddlers should be prepared for wind and the wakes from larger vessels, including cruise ships that transit the main channels.

The scenery is dominated by a rugged, glacially-carved landscape with snow-capped peaks, streams running into the inlet, and views of the Carroll Glacier. Wildlife encounters are common and can be significant; humpback whales and sea otters are frequently seen, and the area is also used by bears. A specific temporary closure to foot traffic and camping was enacted along a shoreline north of the inlet's mouth due to a beached whale carcass attracting bears, highlighting the need to check for current National Park Service regulations and closures before any trip. The water is cold year-round, and the presence of icebergs is noted, indicating proximity to glacial features. There are no facilities or amenities for paddlers within the inlet itself. The overall experience is one of a true, undeveloped wilderness, best suited for experienced, prepared kayakers seeking solitude and dramatic natural encounters.
