Quick practical tips

• Best season: the dry season (roughly February–July, with excellent leopard chances around May–June) is generally best for wildlife viewing; Yala sometimes closes for park rejuvenation (commonly in September–October), so check dates before you book. (yalalk.com)
• Book safaris through reputable lodges (they coordinate trained rangers and park permits) rather than unvetted operators. (atlasandboots.com)
• If low-impact credentials matter to you, look for specific features when comparing: on-site renewable energy (solar), wastewater/greywater recycling, no-single-use-plastics policy, support for local conservation/community programs, and recognized certifications (e.g., Travelife). (Several properties above list those practices in their sustainability statements.) (jetwinghotels.com)

If you want, I can:

• narrow this to your preferred style (budget / luxury / in-park camp vs. park-edge lodge), or
• check current availability/rates for specific dates at any of these properties.

(If you’d like those follow-ups, tell me which property/properties or the dates you have in mind and I’ll look them up.)
