Book an island tour right away - most popular half and full-day trips fill up fast, especially during peak season. The islands around Praslin (Curieuse, St Pierre, Coco, Félicité) are what draw people here, and you'll want a spot on a boat sooner rather than later. Check what's available the day you arrive or book ahead.

Most travellers use Praslin as a base for 2-4 days, taking daily excursions to nearby islands rather than staying put. The island itself has a beach, but the real action is the snorkeling, fishing, and island-hopping tours departing from here.

Half-day trips (Curieuse and St Pierre, or sister-Coco-Félicité snorkeling) work if you're short on time or prefer a lighter schedule. Full-day tours let you hit 3-5 islands and spend proper time snorkeling at each spot - worth it if you're an active traveller. Check what's included (lunch, snacks, equipment) before you book.

A guide really adds value here - they know the best snorkeling spots, can spot wildlife on Curieuse, and handle all the boat logistics. Most tours are guided, and private charters with a skipper are available if you want more control over your itinerary.

April to May and September to October offer calmer seas and fewer crowds. The southeast trade winds (May-September) can make the water choppier, and December-January is wet and hot. Check sea conditions before booking water-based tours, as they can be cancelled or rescheduled.

Chauffeur-driven options are bookable if you want transport around the island. Taxis are available but can be pricey - many visitors stick to their hotel and book tours that pick them up. Check what pickup/dropoff is included with your tour.

Half-day tours are gentler on stamina and sea-legs. Full-day trips involve a lot of boat time and water activity - fine for fit families, but ask about accessibility and comfort before booking. Private charters give you more control over pace and can be tailored to your group's needs.
