CHIANG RAI – As the cool season arrives, Northern Thailand gets ready for an exciting 2025-2026 adventure season. From the mist-covered heights of Doi Inthanon to calm, ethical elephant sanctuaries, the Golden Triangle area has something for every kind of traveller. A memorable trip depends on thoughtful planning and a strong focus on responsible tourism.
This guide, shaped with insight from Chiang Rai, helps travellers plan an unforgettable Northern Thailand adventure.
When to Visit: 2025-2026 Season Overview
The time of year makes a big difference to the experience.
- Cool/dry season (November to February): Best for trekking. This is high season, with cool temperatures, especially at night in the mountains, often dropping to around 10°C to 15°C. Trails are dry and easy to walk. Prices go up, and popular spots get crowded, especially from mid-December to mid-January.
- Green/rainy season (June to October): Ideal for lush scenery and good value. There are fewer visitors and prices are lower. Rice fields glow bright green, and waterfalls are at their strongest. Rain tends to fall in heavy afternoon showers that are fairly predictable, but trails can be muddy and slippery.
- Hot season (March to May): Least suitable for outdoor activities. Temperatures can reach 37°C, and the annual smoke from the “burning season” in March and April often causes poor air quality and hazy views. Long treks during this period are not recommended.
Chiang Rai Times tip: For cooler weather, green views, and fewer crowds, target mid-October to early December 2025.
Trekking Routes & Safety Tips
Northern Thailand is famous for its trekking routes and forest trails. Many paths run through national parks where a licensed guide is required, so booking with a trusted local operator is important.
1. Chiang Mai Jungle Trek (2-3 days)
- Route highlight: A classic mix of jungle walking, village stays, and bamboo rafting.
- Route details: Most treks start in the Mae Wang area, southwest of Chiang Mai, or follow routes in the direction of Pai. Travellers usually walk 3 to 5 hours a day, crossing streams, waterfalls, and steep, humid climbs. On a 3-day trek, the final day often finishes with a slow bamboo raft ride along a river.
- Safety tips:
- Footwear: Good hiking shoes with a strong grip are essential for muddy, slippery paths.
- Homestays: Stays are simple and rustic, with fans instead of air-con, and sometimes no hot water or toilet paper. A quick-dry towel and earplugs are very useful, as roosters start early.
- Hydration: A reusable water bottle and electrolyte sachets help with long, humid walks.
2. Doi Langka Luang, Chiang Rai (2-3 days)
- Route highlight: A tougher, quieter option in Khun Chae National Park, known for its remote feel, evergreen forest, and deep valleys.
- Route details: The main trail is around 17 kilometres and classed as challenging. The area is remote and better suited to travellers with moderate to high fitness. The reward is a sense of wilderness and rich plant and animal life.
- Safety tips:
- Guide needed: A local guide is essential due to the remote location, unmarked sections, and steep paths.
- Wildlife: An experienced guide helps spot birds and other wildlife, and also keeps the group away from snakes and other hazards.
- Preparation: This hike is demanding. Travellers should be in good shape and share any medical conditions with the guide before setting off.
3. Phu Chi Fa, Chiang Rai (day trip or overnight)
- Route highlight: A dramatic peak with a famous “sea of fog” view at sunrise, looking across to Laos.
- Route details: The walk to the top takes about 30 minutes, and the summit sits at 1,628 metres above sea level. To enjoy the sunrise, most people start walking around 40 minutes before first light.
- Safety tips:
- Timing: The path is short and clear, but very dark before dawn. A headlamp or good torch is important.
- Temperature: Early mornings can be bitterly cold, even in the cool season. Warm layers, a fleece, and a light jacket keep the chill away.
Ethical Travel: Elephants & Hill Tribes
Responsible tourism plays a key role in Northern Thailand. Choosing ethical tours helps protect wildlife and supports local communities.
Ethical elephant experiences
Travellers should avoid any camp that offers elephant riding, tricks, shows, or uses hooks and chains. Look for “Saddle Off” projects that allow elephants to live more naturally.
- Recommended ethical sanctuaries (mainly near Chiang Mai and Chiang Rai):
- Elephant Nature Park (ENP): A well-known rescue and rehabilitation centre. Visitors usually watch from platforms or walk near the herd, without climbing on or forcing contact with the elephants.
- Elephant Jungle Sanctuary (EJS): A long-running project that works with Karen hill tribe communities. Programmes focus on feeding and gentle bathing, with respect for the elephants’ comfort and space.
- What to expect: Visitors often help prepare food, feed the elephants, and watch them wander, play, and socialise. Some visits include a relaxed walk to the river for a mud bath or swim.
- Why it matters: Entry fees and bookings help fund food, vet care, and land for the elephants, giving them a safer and more dignified life.
Visiting hill tribe communities
The mountains around Chiang Mai and Chiang Rai are home to many ethnic groups, including Karen, Akha, and Lahu communities.
- Ethical approach: Look for tours that work directly with villagers or community groups, often the same tours that run ethical elephant visits. This way, money goes to the people who live there, and the experience is based on respect, not on staged displays. Avoid trips that treat locals as a “spectacle” for photos.
- What the experience is like: Visits may include learning about traditional farming, herbal medicine, weaving, or cooking. Some tours offer simple homestays in wooden houses, with shared spaces and local food.
- How to be respectful:
- Dress modestly: Shoulders and knees should be covered in temples and villages. Light, loose clothing works well in the heat.
- Ask before taking photos: Always ask for permission, especially when photographing children or elders.
- Shop with kindness: When buying handmade textiles or crafts, avoid bargaining so hard that it feels unfair. A small extra cost to a visitor can make a real difference to the seller.

Smart packing makes a big difference to comfort, safety, and flexibility.
