Quick Answer: Where to go scuba diving and snorkeling in Paraty?: Paraty's top marine spots for snorkeling and beginner scuba diving are Ilha Comprida (the bay's natural aquarium), Ilha dos Ratos, and Lagoa Azul. For first-time scuba divers, no prior experience or swimming certification is required—every participant is paired one-on-one with a certified PADI divemaster for a discovery dive down to 5 meters. Expert tip: water visibility is at its peak on sunny days from spring to summer, and boat tours with snorkeling gear included can be booked online with free cancellation up to 24 hours prior.
The protected bay of Paraty is one of southeastern Brazil's richest marine sanctuaries. Sheltered by the dramatic mountains of Serra da Bocaina, its tranquil, current-free waters offer ideal conditions for snorkeling and scuba diving for beginners and certified divers alike.
1. Paraty's Best Snorkeling and Diving Spots
Cruising through the bay takes you to rocky reefs brimming with vibrant starfish, sea turtles, and colorful schools of tropical fish:
- Ilha Comprida (The Natural Aquarium): The quintessential stop on schooner and speedboat tours. Simply floating on the surface with a snorkel mask, hundreds of yellow-and-black sergeant major fish will surround you. Average depth ranges from 2 to 5 meters with calm, emerald water.
- Ilha dos Ratos & Ilha dos Meros: Regarded as Paraty's premier scuba diving havens. Submerged boulder fields shelter groupers, octopuses, rays, and green sea turtles. There is even an underwater statue of Neptune submerged near Ilha dos Ratos, a favorite landmark for underwater photography.
- Lagoa Azul (Ilha Grande border): A shallow, turquoise natural pool framed by granite rocks and white sand where the water is so clear you can spot marine life right from the boat deck.
- Praia Vermelha & Praia da Lula: Shallow, gentle shorelines ideal for families and younger swimmers putting on a snorkel mask for the very first time.

2. How Discovery Scuba Diving Works for Beginners
Many travelers hesitate to dive because they assume an internationally recognized PADI or NAUI certificate is required. In Paraty, Discovery Scuba Diving (Batismo) is specifically crafted for first-timers:
- On-Board Briefing: During the boat cruise to the dive site, your instructor explains mask clearing, regulator breathing, and hand signals.
- Surface Adaptation: You put on the BCD vest, tank, and mask, floating peacefully next to the boat until you feel completely at ease.
- Guided 1-on-1 Descent: The instructor holds your buoyancy vest throughout the dive, managing depth and air balance. You only need to relax, breathe, and enjoy the marine life.
- Duration: Underwater bottom time typically spans 30 to 45 minutes at safe depths of 4 to 6 meters.
3. Water Visibility and the Best Time to Dive
Water visibility in Paraty's bay ranges between 4 and 15 meters, depending on tides, winds, and recent rainfall:
- Spring and Summer (October to March): Warmer ocean temperatures (around 24°C to 27°C / 75°F to 80°F) make diving comfortable in light rashguards or thin 3mm wetsuits, with exceptionally active marine ecosystems.
- Fall and Winter (April to September): Lower rainfall often yields glass-like water clarity at outer islands. Operators supply full wetsuits for complete thermal comfort.
