I went to Sandakphu and Phalut trek, it was my first trek and the experience was delightful and well-managed by Thrillophila. The support from the Thrillophila before starting the trek could have been better but after reaching the base camp, everything was well-planned and sorted. The homestays and tea houses were clean and comfortable, and the food was delicious and nutritious throughout the trek. The trek guide was resourceful and knowledgeable and always motivated everyone throughout the trek. I can recommend using Thrillophila for Sandakphu and Phalut trek. A short summary of the trek-: 1.
