First-Time Visit to Topslip & Parambikulam – 1 day trip

My wife and I are planning to visit Topslip and Parambikulam either this weekend or next weekend. This will be our first time visiting these places, so we’d really appreciate any advice from those who have been there before. We’ll be traveling by car since two-wheelers are not allowed. We are not sure about the entry process or how tickets work. Questions: 1. Entry Tickets: Where and how do we buy tickets for Topslip and Parambikulam? What’s the cost for entry and any safaris or other activities? 2. Best Timing: When should we reach the locations to make the most of our visit? Are there specific time slots for safaris or activities? 3. Recommendations: Which location is better to spend more time at: Topslip or Parambikulam? 4. Food: How about the food options there? Should we bring own food? Looking forward to your tips and advice! Thanks in advance!
