10 Best Day Trips from Koh Samui 2026: Islands, Temples & Jungle
Key Takeaways: The best day trips from Koh Samui are Ang Thong Marine Park (~$40, the island’s #1 activity), Koh Tao (~$45 including snorkeling), and Koh Pha Ngan (~$25). Most tours depart 7:30-8:30am from Maenam or Nathon pier and return by 5-6pm. Book at least 2-3 days ahead in peak season (December-April). Ang Thong can close in rough weather (October-December) — always confirm conditions before booking.
Koh Samui works exceptionally well as a base for Gulf of Thailand day trips. The island is 30-50 minutes by speedboat from a cluster of world-class marine parks and neighboring islands. See our 5-Day Koh Samui Itinerary for how to slot these into a week’s visit, and the Koh Samui Travel Guide for full planning context.

3. Koh Pha Ngan — Temples & Beaches Without the Party
Distance: ~15km north of Koh Samui
Travel time: 30-35 minutes by ferry or speedboat
Cost: 700-1,000 THB (~$20-30) for transport + activities
Best months: Year-round
[ORIGINAL DATA] While Koh Pha Ngan is best known for the monthly Full Moon Party, 90% of the island is jungle, temple-dotted hills, and quiet beaches that most visitors never see. Haad Rin (Full Moon Beach) is just one of 30+ beaches on the island. A self-guided day on Koh Pha Ngan can be done for 800-1,200 THB total including ferry.
How to spend the day:
– Ferry from Nathon or Maenam pier (6+ daily departures)
– Rent a scooter at the pier (~150 THB/day) for independent exploration
– Thong Nai Pan Noi beach (30-min drive) — arguably prettier than anything on Koh Samui
– Wat Khao Tham temple with hilltop views
– Return on late-afternoon ferry
4. Na Muang Waterfall — Easiest Inland Day Trip
Distance: ~10km from Chaweng
Travel time: 20-25 minutes by scooter
Cost: Free (parking ~20 THB)
Best months: Year-round; best October-March after rains
Koh Samui’s most accessible waterfall requires no guide and no boat. Na Muang Waterfall 1 is a 10-minute easy walk to a natural pool — good for swimming and photos. Na Muang Waterfall 2 is 30-40 minutes uphill and significantly more impressive.
See Best Things to Do in Koh Samui for the full Na Muang hiking guide.
5. Secret Buddha Garden (Magic Garden)
Distance: ~12km from Chaweng, in the island’s interior
Travel time: 30-40 minutes by scooter (steep mountain road)
Cost: Free
Best months: Year-round
A hillside sculpture garden created by a local farmer over several decades, tucked in the jungle at 500m elevation. Dozens of Buddhist and Hindu statues among tropical trees. The mountain road getting there is half the attraction — sweeping views over the south coast.
6. Koh Madsum (Pig Island) — Quickest Beach Escape
Distance: ~5km south of Koh Samui
Travel time: 20-25 minutes by longtail boat
Cost: 700-900 THB (~$20-25) for boat + fees
Best months: December-September
A small, uninhabited island with a single beach, clear water, and the famous “pigs that swim.” The island’s resident pigs swim out to meet arriving boats. Good snorkeling directly from the beach. Full-day tours include Koh Madsum and nearby Koh Tan (slightly larger, with a small village).
7. Koh Nang Yuan — Most Photogenic Day Trip
Distance: ~80km north, adjacent to Koh Tao
Travel time: 2-2.5 hours
Cost: 1,700-2,200 THB (~$50-65) including entry fee
Best months: March-October
Three rocky islets connected by two sandbars create what is consistently voted one of Southeast Asia’s most photographed island views. Usually combined with the Koh Tao trip. The entry fee to Koh Nang Yuan (~200 THB) restricts crowds and no plastic bottles are allowed on the island.
8. Koh Samui Elephant Sanctuary (Half-Day)
Distance: ~12km inland
Travel time: 20-30 minutes (hotel pickup included)
Cost: 1,500-2,000 THB (~$42-55)
Best months: Year-round
Not a traditional “day trip” since it’s on Koh Samui itself, but pairs well with Na Muang Waterfall for a full jungle day. Spend the morning at the ethical elephant sanctuary (no riding, free-roaming herd), then drive to the waterfall for lunch and swimming.

9. Nathon Town Walking Tour — Local Culture
Distance: 15km from Chaweng
Travel time: 20 minutes by scooter
Cost: Free
Best months: Year-round
Koh Samui’s administrative capital is almost entirely local. A 1-2 hour walk through the old town reveals Chinese shophouses, local markets, temples, and the ferry pier. The Sunday night market (4pm-9pm) has the island’s cheapest street food.
10. Koh Phangan Full Moon Party (Night Trip)
Distance: 15km north
Travel time: 35 minutes by speedboat
Cost: 800-1,500 THB (~$22-42) including transport
Best months: Year-round (monthly)
Party boats run from Koh Samui to Haad Rin beach for the monthly Full Moon Party (capacity 20,000-30,000 people at peak). Early return boats leave at 4am, late boats at 6am. Check exact dates as the party moves to avoid Buddhist holidays.
