Here’s a review summary of Pang Sida National Park in Sa Kaeo province (Thailand) — what people like, what to look out for, and some tips if you go.
✅ What’s great
• One of the standout features is the butterfly-watching. The park is often noted for having hundreds of species of butterflies gathering in certain seasons. For example, the park hosts a butterfly festival from May to July — and in that time you can see thousands of butterflies. 
• The scenery is lush: forested hills, streams, waterfalls, and relatively less crowded than some of the major parks. 
• For nature-lovers: plenty of flora & fauna. The park is part of the larger UNESCO forest complex. 
• Many reviewers mention friendly staff, good facilities at the HQ (visitor centre, camping, bungalow options) and a sense of being “away from it all”. For example: “Extremely helpful and friendly staff which I have never experienced before in a Thai National park…”

⚠️ What to be aware of / when it’s less ideal
• Seasonality matters. Visiting outside peak times means the waterfall may have low water, some trails may be less scenic and some highlights (butterflies) may be fewer. For instance: visiting Pang Sida when the water was low.” 
• The access road can be rough: many mentions of dirt tracks, need for decent clearance, rainy season making things harder. For example: “Most of the road is not good for private cars.” 
• Entry fees are steeper for foreigners: some travellers noted this disparity. 
• Facilities beyond the main areas may be basic. If you go deep into the park (for viewpoints, trails) be prepared (bring water, supplies).
• Wildlife warnings: some trails have wild animals (elephants, etc) so you need to follow park guidance.

🕒 Best time & what to do
• Best time for butterflies: May to July (or around the rainy onset) when many species congregate. 
• For waterfalls at good flow: rainy or shortly‐after rainy seasons are better. Dry season may mean less water.
• Trails and viewpoints: If you enjoy hiking, forest views, less‐trodden tracks – allow extra time, perhaps stay overnight.
• Arrive early in the day if you want to catch the butterfly activity (they are more active in the morning).

🔍 My overall rating & recommendation
If you love nature, butterflies, forest trails and don’t mind a little adventure (rougher roads, maybe fewer amenities), it’s very much worth a visit.
If you prefer perfectly paved roads, large facilities, and guaranteed waterfall flow year-round, you might find it less comfortable during certain seasons.

🎒 Tips for your visit
• Bring sturdy shoes/trail shoes (some slippery or uneven trails).
• If driving, use a higher clearance car, consider conditions (especially in rainy season).
• Check weather & water level conditions ahead of time if you want waterfall view.
• Bring water, snacks – if you go deeper, facilities are limited.
• Respect rules: wildlife is real (elephants, etc), follow guidance.
• If you want butterflies, aim for early morning and the good season.
• Plan for transport: own transport...
