Shimla Experience: Please avoid going in peak summer as this summer capital is as hot as India capital. Should be renamed as 'Winter capital'. Avoid train ride in after noon in May-Jun. Nothing much to enjoy including Mall {felt like Mumbai galli bazar} as the best is still Gangtok Mall.
Food, sight-seeing and shopping: Kufri - Treacherous horse ride{no other option to promote locals} to top with nothing much to do. Must be good in winters if it snows.
Nalderah - Asia's natural Golf course still operational also needs a horse ride to reach the top but better than Kufri as one can find less crowd and few shades to hide in scorching heat of May.
Activities & things to do: Could not find of interest
Travel tips, How to reach, travel warnings etc: Avoid in Summer May & June as all the greens of mountain slopes now converted into white concrete
