Looking for an easy rainy-season hiking trail for beginners? The Kong Kaeo Nature Trail in Khao Yai National Park is a great choice. This short and scenic loop trail is perfect for first-time hikers. It’s relatively easy to walk, taking about 30–45 minutes to complete the 1.2-kilometer route, including stops for photos and nature observation. No guide is required, and the path is clearly marked.

The 200th Anniversary Thai–U.S. Friendship Trail in Khao Yai National Park is a newly established route created to celebrate the longstanding relationship between Thailand and the United States. In addition to marking the historical ties between the two nations, the trail follows standards and guidance developed by the U.S. National Park Service. Along the way, hikers will experience a rich ecosystem, including dry evergreen forests, secondary forests, and open grasslands. Common wildlife sightings include Siamese fireback pheasants, silver pheasants, gibbons, and hornbills. Please note that this trail requires a park guide to accompany all visitors.

3. Erawan Waterfall Trail, Erawan National Park

If you're a beginner looking to experience hiking during the rainy season, the Erawan Waterfall Trail in Erawan National Park, Kanchanaburi, is a fantastic choice. This is one of Thailand’s most famous and majestic waterfalls, attracting both local and international tourists. The trail spans approximately 2,200 meters and features seven distinct tiers, each with its own unique beauty and charm.

Along the way, hikers can cool off and swim at certain tiers to rest and refresh.

4. Phu Soi Dao Hiking Trail, Uttaradit

When it comes to rainy season hiking destinations in Thailand, Phu Soi Dao is always at the top of the list for many avid hikers. This is the most beautiful time to visit the area, thanks to the seasonal blooming of the “Naka crest flowers” (Murdannia giganteum), which transform the pine forest meadow into the largest wildflower field of its kind in Thailand. These purple-blue flowers bloom alongside other species like the golden-hued “Soi Suwannaa” and the fragrant “Rak Hom” grass, all set against a misty backdrop and cool mountain air. The trail features a variety of landscapes — from hills and pine forests to flower fields — and includes five main slopes: "Goodbye Hill", "Challenge Hill", "Bamboo Hill", "Tiger Hill", and the intimidatingly named "Death Hill." While the hike isn't extremely technical and is accessible for beginners, it does require endurance due to the length and steady incline.

• Pros: You’ll experience the breathtaking beauty of wildflower meadows in full bloom, including Naka crest flowers, Soi Suwannaa, and more — especially vivid during the rainy season.

The Phu Wua hiking trail is particularly famous for its large and scenic waterfalls. During the rainy season, the forest comes alive with wildflowers that bloom only at this time of year.

6. Phu Kradueng National Park Hiking Trail, Loei Province

Phu Kradueng is one of the most iconic hiking trails in Thailand — a bucket-list destination for many beginner trekkers looking to conquer a serious challenge. While it combines both easy and difficult sections, we’ve placed it among the more adventurous trails for thrill-seekers. If you love forest trekking, this is one trail you can’t miss. As the saying goes, “If you want to prove true love, hike up Phu Kradueng together.” The trek to the summit is about 9 kilometers long and is divided into distinct segments: “Sam Haek” is a steep uphill climb, followed by “Sam Bon,” a mix of slopes and flat sections. Then comes “Sam Kok Kok,” a mildly undulating route, and “Sam Moey,” a blend of flat terrain and gentle climbs. After that, you'll reach “Lang Pae,” one of the steepest parts of the hike, before arriving at the flat plateau of “Wang Kwang.” It’s definitely exhausting — but luckily, porter services are available to carry your bags if needed!

The Pitu Kro – Thi Lo Su Waterfall trail in Tak Province is a true test of endurance — both for your legs and your spirit. This demanding trail takes you through humid, muddy, and slippery terrain, especially during the rainy season when heavy downpours can turn paths into rivers of mud. At certain points, you’ll even need to cross strong-flowing streams to reach the waterfalls. Located within the Umphang Wildlife Sanctuary near Doi Mamuang Sam Muen and the Thai–Myanmar border, this area is a hidden gem in the deep forest. The highlight of the trek is the magnificent Pitu Kro Waterfall, shaped like a heart and surrounded by pristine nature. During the rainy season, it becomes even more spectacular as water gushes powerfully from springs atop the mountain.
