Dive Site Location & Key Facts
Dive Site Overview
A perfect natural harbor, Hideaway Bay often marks the first dive site for Similan Islands liveaboard trips, largely thanks to its reliably calm waters. Off the south of Island 5, this location elegantly combines two distinct dive experiences into a single outing.
Upon descent, divers are greeted by a bright white, steep sandy slope intricately covered with thriving hard corals. An expansive reef garden here provides ample opportunities for diverse marine creatures to find refuge and hunt. These shallower sections boast vibrant reef life, with numerous small fish darting among the coral heads.
Moving deeper, more experienced divers can explore the adjacent Tuna Wreck. This deliberate shipwreck, alongside the natural reef topography, creates a truly dynamic environment.
Divers navigate gentle reef slopes before transitioning into the deeper, more complex wreck structure, appealing to various skill levels. Its extensive coral growth on the surrounding reef offers a rich visual spectacle for all certification levels, while the deeper wreck presents specific challenges for advanced divers, requiring careful buoyancy control.
The site's varied topography, from the bright sandy bottom to the intricate coral formations and the dark recesses of the wreck, ensures a compelling dive for every visitor.

Dive Experience & Conditions
Entering the water at Hideaway Bay provides options tailored for different skill levels. Less experienced divers can readily orient themselves on the sheltered, calm reef, allowing comfortable acclimation to their gear amidst a vibrant hard coral garden. These calmer sections are ideal for building confidence. More experienced divers often choose to start their dive at the Tuna Wreck, a deeper, more demanding segment of the site. Water conditions generally remain calm within the bay, contributing to an overall relaxed dive atmosphere, though currents can vary near deeper structures or during specific tidal movements.
Dive Difficulty & Safety Guidelines
When planning a dive at Hideaway Bay, divers must always be mindful of depth and no-decompression limits (NDLs), especially when exploring the Tuna Wreck. This site offers distinct sections requiring different skill sets; the deep wreck dive, with its top around 28 m (92 ft) and bottoming out at 40 m, is suitable for Advanced Open Water divers or higher. Less experienced individuals should confine their dives to the shallower, gentle sloping reef.
Park regulations mandate the closure of the Similan Marine National Park from mid-May to mid-October, preventing access to Hideaway Bay during these months for conservation and safety reasons.
