Here’s a detailed look at group camping & adventure tours in Sri Lanka — what kinds are available, strengths & challenges, plus suggestions for designing or using these tours. If you like, I can map out some possible adventure‑camp routes around Anuradhapura.

What exists already: Camping & Adventure Tour Options

These are some of the tour operators and services that offer group camping, adventure treks, wildlife safaris etc in Sri Lanka:

What Makes These Tours Attractive for Groups

Here are some strengths / selling points:

• Immersive nature experience — staying in wild or semi‑wild places, seeing wildlife, stars at night, interactions with remote landscapes.

• Team bonding & group dynamics — group camping often leads to shared campfire meals, stories, collaborative activities.

• Variety of adventure: trekking, wildlife safari, bird watching, river walks, sometimes canoeing or kayaking.

• Flexibility for different levels — can offer easy/moderate vs challenging treks. Glamping for comfort, rustic camping for more adventurous.

• Eco & sustainable tourism appeal — many operators are using eco‑friendly camps, minimal impact, solar lighting, etc.

Challenges / What to Manage Well

To run or participate in great group camping / adventure tours you need to watch out for:

• Logistics & safety: transport to remote sites; ensuring guides are licensed; first aid, safety equipment.

• Group size vs environmental impact: big groups can damage trails, make noise, generate waste; must plan low‑impact camping.

• Weather / terrain variability: rain, slippery trails, river levels etc. can affect safety & comfort.

• Comfort vs authenticity trade‑off: more rustic means less comfort; glamping costs more. Need to match customer expectations.

• Permits / legal permissions: some areas (national parks, forest reserves) require permits. Camping might be restricted in sensitive zones.

• Seasonality: monsoon, dry seasons affect accessibility, trail conditions, wildlife visibility.

  Day 2: Trek through forest trails, visit waterfalls, overnight at a wild campsite
  Day 3: Peak hike + home stay in local village, learn cooking, sleep under stars
  Day 4: Return + optional spa / relaxation

• 5‑Day Wildlife + Jungle + Beach Combo
  Start in Udawalawe or Yala: safari + night camping in eco‑camp
  Jungle trek in Sinharaja or surrounding rainforest
  River or waterfall hikes
  Finish by the beach: camp on beach or near coastline

Potential in & around Anuradhapura Region

Since you’re based in Anuradhapura, here are thoughts on what adventure‑camping could work locally / regionally:

• Use ancient forest reserves or dry zone regions for night camping under stars with views of old ruins illuminated (dawn / dusk).

• Combine archaeology + camping: stay in tents near ruins (with permission) and do early morning guided walks.

• River / tank / lake camping: there are many tanks (“wewa”) and water bodies around; might be able to base camping near lakes, include birdwatching, fishing etc.

• Trekking in nearby hills or small escarpments (depending on geography) for moderate adventure.

• Connecting to wildlife areas: Wilpattu is not too far; combining a safari + camping package could work.
