About this spot
Bijoutier Pass cuts through Alphonse Island as a dramatic underwater channel descending 15 to 40 meters. This is serious diving for experienced divers only. The pass is a natural funnel where larger pelagic fish congregate, drawn by upwelling nutrients and natural prey. You'll encounter strong currents here—sometimes your only option is to ride them and plan your ascent carefully. The geological setup creates constant motion and energy that makes every dive different. The pass works year-round, though exact seasonal patterns for this specific site are not well documented. Local knowledge and real-time conditions matter more than a calendar. Most operators at Alphonse plan dives based on tidal flow and daily reports. Visibility and water temperature data for Bijoutier are not widely published, so ask your guide before descent. This is not a beginner's playground. You need solid buoyancy control, current experience, and comfort with deeper water. The reward is genuine pelagic action and the chance to see Alphonse's open-water inhabitants in their element. Single divers or small groups work best here; guides who know the pass intimately make the difference between a great dive and a difficult one.

FAQ
›When is the best time to dive Bijoutier Pass?
Year-round diving is possible at Alphonse, but exact seasonal conditions for Bijoutier Pass are not widely documented. Tidal flow and current strength vary daily and influence dive planning more than the month. Check with local operators for current conditions and recent dives before you arrive.
›What depth and difficulty level should I expect?
Bijoutier Pass descends 15 to 40 meters and is rated advanced. Strong currents are common. You must have solid buoyancy control, previous deep-dive experience, and comfort handling current. This is not suitable for newly certified divers.
›What marine life will I see?
Pelagic fish are the main draw—the pass acts as a feeding corridor where larger open-water species hunt. Exact species composition varies by tide and season. Local guides can tell you what's been active recently.
›How do I access Bijoutier Pass and are permits needed?
Alphonse Island is not inside a marine protected area, so standard Seychelles diving rules apply. Most divers reach the pass via boat from island lodges or liveaboards. Confirm access and any local requirements with your operator when booking.
