It's so beautiful and amazing to stay there. Take dip in the holy lake and then visit holy Gururdwara. You can sit there and listen last Ardaas around 12 PM. After spending 2 hrs, we started trekking back to downwards. Depends upon the weather conditions and physical fitness, you can climb down directly till Phulna same day or one decide to stay in Ghangaria for night and start trek back to Phulna in next morning early. Other option is to take Helicopter ride from Ghangaria to GovindGhat which takes just 5 mins of air travel. We decided to trek back on foot till phulna, and reached there around 7 in evening.
Next Day We took Rishikesh Bus in early morning 5:00 am. It was raining from night. And due to this Bus has to Stop in Joshimath for sometime, as early rain started landslides in multiple places. This allowed us to witness a beautiful weather in Joshimath.
